Question about 1989 Dodge Dynasty

1 Answer

Can't turn rear drum freely after replacing brake shoes, backed them off with self adjuster, still no freedom, do you think the inside bearing is at fault?

Self-adjuster postion is by the book, shoes are properly installed w/ new springs, the outside bearing nut is only hand tightened, wonder if the wheel hub is out of round ? or did the inside or inboard bearing not get seated properly !

    Look i may old and decrepit with creaky joints ,and years out of date with all this fancy nerdy software on modern cars but brakes ? well they havent changed much since the model T ,whatever your problem is then its physical now if was around the corner i would call in demand my cup of tea before i started ,have a ciggy which includes a good cough and see what the problem is straight away .Now when setting up rear brakes the first thing you must do is to slacken off the handbrake cable as many a dealer quick fix fitter on bonus will just adjust the handbrake cable ,So slacken it then clean the rusty lip ,here i use a small angle grinder then making sure all the springs are on correctly ECT ECT i then adjust the automatic adjusters manually ,tip on this vary according to brake manufacturer.Then when they are just catching the drum i tap around the drum with a fairly heavy hammer then remove the drum and adjust up a bit more and repeat the tapping procedure only then when iam happy with the adjustment will i adjust the cable up to three clicks on the handbrake ,yes the brakes will drag a bit but? they soon bed in.If its a bearing problem then you will feel a grounchy feeling in the bearing but watch out as some vehicles use a collapsable spacer inside the bearing between the inner and outer bearing and if you havent noticed it fall out and roll away ?? YES happens to the best of us and with my luck they always roll down a drain

    thanks colin, the bottom line on this problem was found during the state inspection, my mechanic, determined the right rear parking brake cable was at fault , most rear parking brake cables freeze up after time ,a common problem , I knew they would need addressed sooner or later tryed to get away with it but my luck wasn't having it. I needed a winter car, it was sitting for a while, caused my own problems, it bit me with every tooth it had, thanks colin, I was getting shell shock after spending so much time repairing practically every thing this vehicle had to throw at me. been working on all my vehicles for 42 years, sometimes things go good, some not so good, nature of the beast, thanks again colin , lets keep helping people, they need us

SOURCE: passenger side rear brake locked up.

It's probably the emergency brake cable that is stuck. Check that first. When I get a drum brake that is totally frozen up (like been sitting for 40 yrs) I often use 2 or 3 pry bars, WD40 and short handle sledge hammer to pry a little on both sides, liberally keep penetrating oil squirted on the shoes and tap on all sides. Eventually drum will come off, but sometimes it takes like maybe 1/2 hour. Shoes will have to be replaced, but they are probably shot anyway. The drums for the caravans are cheap, so I would not only get them, but the spring kit from the parts house as well.

There is an access hole in the back side of the dust cover at the bottom. You can get a screw driver in there, and move the adjuster. If you can't seem to get it, then open the bleeder screw on the wheel cylinder, and move the drum side to side to push the shoes back together.

SOURCE: Are the rear drum brakes on 1997 stratus self adjusting or manual

It should be self adjusting (when u back up and apply the brakes, it adjusts ), and can also be manually adjusted (thru removal of the rubber plug on the backing plate). The adjuster (star wheel) can seize due to rusting and it won't adjust automatically or manually. Whenever u do a brake job, spray it w/ wd-40 and turn it back and forth several times to make sure it is free, then I put a dab of high temp. brake grease on the threads (only a small amount, as u don't want it dropping off and getting on the brake shoes).

Cant get drum back on how do I adjust the brake pads


The brake shoes can be adjusted inward by the self-adjusting mechanism at the bottom of the shoes. Turn the adjuster wheel so the shoes will just fit inside the drum. After you get the drum on, use a screwdriver through the slot on back of brake plate to turn the adjuster wheel enough clicks outward to where the shoes are just away from the drum. Turn the drum by hand. When shoes are out enough without stopping the drum, you have it right. When all done and testing out, the self-adjusters will set adjustment by backing in reverse and hitting the brakes. Do this two or three times-you may hear the self-adjusting wheel click with each time- it is adjusting the shoes to the proper distance from the drum.

Your description sounds like the brakes are WAY out of adjustment. The brake cylinders need the shoes to hit the drum or they will do exactly what you describe. I always adjust the shoes until they lock the wheel, then back off until the wheel spins freely, usually 8 to 20 clicks.

PROBLEM WITH REAR BRAKES GRABBING AND LOCKING WAS PRESENT PRIOR TO ME REPLACING ALL PARTS AS A PROCESS OF ELIMINATION. REAR DRUMS SPIN FREELY SO THERE IS PLENTY OF CLEARANCE. I'M OPEN FOR IDEAS


Hi, it is possible there is too much clearance. Some things that can cause grabbing are hydraulic oil leaking from wheel brake cylinder, excessive brake lining dust, or shoes not adjusted up to the drum. Your self-adjusters should be pulling the shoes up to the drum whenever you backup, but one or both may not be adjusting. You can manually adjust them if that is the case. Please inspect and check these items, and let me know if you have any questions.

Replacing rear brakes



REMOVAL & INSTALLATION
It is a good idea to only disassemble and assemble one side at a time, leaving the other side intact as a reference.

  1. Raise and support the vehicle safely.
  2. Remove the brake drum.
  3. Disconnect the parking brake rear cable and conduit.
  4. Remove the brake shoe hold-down springs and brake shoe hold-down pins.
  5. Remove the brake shoe adjusting screw spring.
  6. Remove the brake shoe adjusting lever and adjuster screw.
  7. Remove the brake shoe retracting spring.
  8. Remove the brake shoes from the backing plate.
  9. Remove and discard the parking brake lever clip. Remove the washer.
  10. Remove the parking brake lever from the rear brake shoe.

To install:
  1. Thoroughly clean the backing plate with brake cleaning solvent and dry completely.
  2. Use silicone grease to lubricate the brake backing plate-to-brake shoe contact areas.
  3. Apply a light coating of premium grease to the threaded areas of the adjuster. Turn the adjuster in and out to spread the lubricant. Turn the adjuster all the way down on the screw and loosen one-half turn.
  4. Install the parking brake lever to the rear (secondary) brake shoe with a new clip.
  5. Position the brake shoes on the backing plate and install the brake shoe hold-down springs.
  6. Attach the parking brake rear cable and conduit to the parking brake lever.
  7. Attach the brake shoe retracting spring.

The socket end of the brake adjuster screw is stamped with "R" or "L" to indicate that it is to be installed either on the right (passenger's side) or left (driver's side) of the vehicle. The adjuster nuts can be distinguished by the number of grooves machined around the body of the nut. Two grooves indicate a right-hand adjuster nut and one groove indicates a left-hand adjuster nut. Another way to identify brake adjuster assemblies is to check thread pitch. The right side adjuster assembly has right-hand threads and the left side has left-hand threads. If installed correctly, the brake adjuster assembly will increase in length when the brake shoe adjusting lever is operated.
  1. Install brake adjuster screw in the slots on the brake shoes. The wider slot on the socket end must fit in the slot on the front (primary) brake shoe.
  2. Install the brake shoe adjusting lever on the lever pin.
  3. Install the brake adjusting screw in the slot on the secondary brake shoe and in the slot on the brake shoe lever. The brake shoe adjusting lever should contact the brake adjuster screw.
  4. Adjust the brake shoes.
  5. Install the drums.


ADJUSTMENTS

The drum brakes are self-adjusting and require a manual adjustment only after the brake shoes have been replaced, or when the length of the adjusting screw has been changed while performing some other service operation.
Drum Installed

  1. Raise and support the vehicle safely.
  2. Remove the rubber plug from the adjusting slot on the backing plate.
  3. Insert a Brake Adjustment Tool (D81L-1103-C) or equivalent into the slot and engage the lowest possible tooth on the starwheel. Move the end of the brake spoon downward to move the starwheel upward and expand the adjusting screw. Repeat this operation until the brakes lock the wheels.
  4. Insert a small screwdriver or piece of firm wire (coat hanger wire) into the adjusting slot and push the automatic adjusting lever out and free of the starwheel on the adjusting screw and hold it there.
  5. Engage the topmost tooth possible on the starwheel with the brake adjusting spoon. Move the end of the adjusting spoon upward to move the adjusting screw starwheel downward and contract the adjusting screw. Back off the adjusting screw starwheel until the wheel spins freely with a minimum of drag. Keep track of the number of turns that the starwheel is backed off, or the number of strokes taken with the brake adjusting spoon.
  6. Repeat this operation for the other side. When backing off the brakes on the other side, the starwheel adjuster must be backed off the same number of turns to prevent side-to-side brake pull.
  7. When the brakes are adjusted, make several stops while backing the vehicle to equalize the brakes on both of the wheels.
  8. Lower the vehicle.

Drum Removed
See Figure 2

Fig. Fig. 2: When using a brake adjustment gauge, first measure the inside diameter of the drum (top) and then adjust the brakes shoes to the proper outside diameter (bottom)

  1. Remove the brake drum.
  2. Make sure that the shoe-to-contact pad areas are clean and properly lubricated.
  3. Using a Brake Adjustment Gauge (D81L-1103-A) or equivalent, check the inside diameter of the drum.
  4. Measure across the diameter of the assembled brake shoes, at their widest point.
  5. Turn the adjusting screw so that the diameter of the shoes is 0.030 in. (0.76mm) less than the brake drum inner diameter.
  6. Install the drum.


INSPECTION

See Figure 3


0900c152800ae433.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: Measure brake shoe thickness in several places around the shoe
Inspect the brake shoes for wear using a ruler or Vernier caliper. Compare measurements to the brake specifications chart. If the lining is thinner than specification or there is evidence of the lining being contaminated by brake fluid or oil, replace all brake pad assemblies (a complete axle set).

How to remove brake rotors on a 1996 ford explorer


How to replace the rear brake pads on a 1995 through 2001 Ford Explorer The system utilizes a drum-in-hat type rear brake rotor. The integral drum allows the use of a drum-and-shoe type parking brake system. All other components are similar to their front disc brake components Remove the two bolts on either side of the brake hose with the rubber boots. Do not remove the four bolts where the axle ties in. The two bolts to be removed require a 10mm socket/wrench. Loosen the pads from the caliper Rotor Removal In order to take the rotors off (replace with new or have them machined), it is best to loosen the emergency brake shoes. To do this, behind the rotors, in the back there is a rubber plug, remove that and you can use a screw driver to engage the teeth of the adjusting screw, turn it clockwise to loosen, usually 10-20 teeth. Usually this means turn it downward. After this, it may still be difficult to get the rotors off without tapping them. Use a rubber mallet and hit them from behind. Before really whacking the rotor, make sure you have loosened the adjusting screw enough. It may take heavy swings of the rubber hammer to do this. It will eventually break loose. Parking Brake You might want to check the parking brake while you are here. To remove:
  • Remove the rear disc brake rotor.
  • Remove the outboard return spring.
  • Remove the adjusting screw spring.
  • Remove the rear brake shoe hold-down spring and pin.
  • Remove the brake shoe adjusting screw and nut.
  • Remove the front brake shoe hold-down spring and pin.
  • Remove both parking brake shoes and the inboard return spring.
  • Check the parking brake lever for excessive wear and replace as necessary.
To install:
  • Position the front parking brake shoe to the backing plate and install the hold-down pin and spring.
  • Install the rear parking brake shoe with the inboard return spring.
  • Position the brake shoe adjuster screw and nut on the shoes and install the rear shoe hold-down pin and spring.
  • Install the brake shoe adjuster spring.
  • Install the outboard return spring.
  • Adjust the parking brake shoes and install the rotor, caliper and wheel.
  • Lower the vehicle and tighten the wheel lug nuts to 100 ft. lbs. (135 Nm).
ADJUSTMENT
  • Measure the inside of the drum portion of the rear brake rotor
  • Remove the rear disc brake rotor.
  • Using Brake Adjustment Gauge D81L-1103-A or equivalent, measure the inside diameter of the drum portion of the rear disc brake rotor.
  • Subtract 0.020 in. (0.508mm) from the first measurement, adjust the brake shoes to that size
  • Adjust the parking brake adjuster screw until the outside diameter of the parking brake shoes measures 0.020 in. (0.508mm) less than the drum measurement.
  • Install the rear disc brake rotor.
Reassembly Reassembly is easy. Put new or machined rotors back on by sliding them over the lugs (they should slide on easily.) Loosen bleeder valve (having a catch bottle handy is good). Push calipers in slowly (using a c-clamp or large channel lock pliers), close bleeder valve. Put on pads. Lubricate metal clips with small amount of anti-seize. Re-adjust the emergency brake by turning the opposite direction from loosening. Refill the brake master cylinder

Wanting to check brakes on rear of my 2001 Mercury Sable but can't back the shoes away from the drums?


The drums have a "ridge" on the inside of the metal NOT worn off by the shoes.The shoes have expanded to their clearance to the worn drum The self adjuster wheel will need to be turned back to make the diameter of the shoes smaller. I don't remember a "window" at the rear of the drum (where in the old days we put in a flat "screwdriver" adjuster and rotated the wheel to adjust the shoes). You may have to force the drum off (and replace it).

Rear wheel bearing (1999) very loud, how do i fix it??


Before changing the real wheel bearings, you should thoroughly inspect your rear brakes. You would disassemble the back brakes anyway to change the bearings, and changing the brakes is easier. Remember to block the wheels up front, yes - safety first. As you pull off the rear drums, if you have to struggle to get them off, then that is a definite sign of wear and you'll need to do a rear brake job. As rear drum brakes are used, they have an auto adjust screw that tests and resets your brakes to ensure they are at proper distance to the drum surface. As brake shoes wear into the drums, they can create a groove or lip on the inside of the drum that the brakes will get caught upon when you try to remove worn brake drums. There should be a little hole on the interior side of the brake drum assembly and where you can fit a brake adjustment tool into. After you get the tool in there, it will touch against a star shaped wheel which is actually an adjusting nut. If you have a very small phillips screwdriver, place it inside this same hole and push the little arm that is touching this little star shaped nut. Everytime you back up and hit the brakes, this automatic adjustment lever pushes down on the little star shaped nut making sure that the brakes are not loose (keeps them snug). After you have this lever pushed away from the star shaped nut, use the brake tool to begin turning the star shaped nut until you have moved the screw back together, and the brake shoes have moved back towards each other, and you should then be able to easilly slide the brake drum off.

Once you get the rear drums off, you should try to turn the rear hub on each side and listen for noise and the feel of metal grinding (it should turn freely and smoothly). If the brake pads and drums are in good shape (plenty of brake padding left and no signs of metal wear upon the drums) AND you can feel and or hear the grinding as you turn the wheel hub assembly, then proceed with continuing to replace the rear wheel bearings. However, the more likely scenario is that you need a rear brake job, and doing a brake job is still easier than continuing to tear your brakes apart to replace the hub bearings.

You can check out a copy of Chilton's Auto Repair Manual Hyundai Excel 1986 - 1993 from your local public library. You can also buy this manual on the internet by using your favorite search engine (yahoo, google, etc) to locate a book seller.
