Changed rear brakes on 2004 kia spectra put new caliper on passenger side and pads on both sides now driver rear looked up and passenger side wont do anything


You may need to adjust the cable for your hand brake. The driver's side is too tight and the passenger side is too loose. Best thing to do is drop the hand brake (e-brake) down, loosen the adjuster on the drum, then lift the hand brake until you hear 5 clicks. Then adjust the handbrake cable on both sides until the disk just stops.

I put new brakes in my saturn. i put new front calipers,rotors and pads and power bleed front only. i also put new brake pads in rear but did not replace drums.after all that i can't get a hard brake...


try adjusting the rear brake shoes but.....spin the rear wheels first is u get the feeling of the shoes grabbing then releasing ( the tire gets loose then tight as u rotate it) u will need to have the drums cut on a brake lathe or replaced...when u have this done , then adjust the rear shoes until u get a slight drag on the rear wheels..go pump the brake pedal to seat the shoes if the wheel spins free adjust the shoes more an repeat until they have a slight drag after pumping the brake pedal

Can i adjust e brake @ handle, or do i need to pull rotors and off to do it?


They should be self adjusting. Why are you trying to adjust them...too tight ? Too loose ?...you may just need new pads as the e-brake uses diff brakes than the hydraulic system brakes. Hope this helps !

Emergency brake adjustment


There are 2 ways. It has rear drum in hat style brakes, meaning it has pads and rotors for basic brakes, but incorporated in the rotor is a drum with park brake shoes inside. Remove rear pads and rotors, check the condition of the park brake shoes. Tighten the star wheel adjuster while installing the rotor, keep repeating until rotor feels snug pushing on. Repeat other side reassemble. If still doesn't feel tight, there is an adjustment nut on the left rear side on the cable. The nut is where the 2 rear cables meet, it can be tightened. Do not tighten first, if you ever need park brake shoes later they will not allow the rotors to go back on.

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

I just did a rear brake service with new brake shoes and now my e brake lever in the drivers side goes all the way to the floor before getting tight


If you put it all together correctly your problem may be that you did not adjust the brakes after you installed them. You need to turn the adjusting wheel till the brakes shoes just start to drag against the drum.Usually using a brake tool with the wheel on.
