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.

Emergency brake not working after changing rear brake shoes on a 1990 gmc pickup 1500 series? And how do I release the emergency pedal from the floor? It won't release when you step on it?


Was the brake shoes replacement a DIY or professional job. If DIY, are you certain that you reassembled the brakes properly? Does the truck move at all? Does it feel as though the e-brake is applied? With the e-brake pedal to the floor, the truck should not move freely when the accelerator pedal is depressed. The emergency brake assemblies on both rear wheels are connected to a cable assembly that ultimately leads to the e-brake pedal. The cable has an adjustment point and a spring tensioner to prevent slack in the cable. First, crawl under and physically check the cable tension. If it's loose, either the cables are not connected to the rear wheels' brake assemblies, not connected properly, or the cable and/or pedal is damaged/broken. If the cable is tight - overly tight, but the e-brake is not holding the truck from moving, the e-brake levers attached to the shoes inside the brake drums are likely not installed correctly. Double check your installation and consider replacing the e-brake cable (as a precaution). As for the pedal, you may have to remove it in order to get the ratchet-locking mechanism to release.
Of course, if this was a professional job, call the shop and have them make it right. Good luck.

Why would my emergency brake not hold? I have installed new drums, dealer replaced cable three yrs ago and has not been tight since. I have gone back several times, and had adjustments, what else can be...


Make sure you have lots of "meat" on your brake shoes.
Emergency brakes only apply rear brakes by using shoes against the drum, that are pulled by the cable, that's attached to the emergency brake lever / pedal....and actuated by the driver.

It has to be one of those three components...may have to pull the drum and actuate the pedal / lever to see if the cable spreads the shoes and make adjustments from there.

If your back brakes don't hold...it can also cause the ABS light to illuminate...

Hope this helps...

Had no auto matic adjusting lever can I put new brake shoes without replacing adjusting lever on 1994 Hyundia excel rear brake driver side


The rear brake drums are drum brakes on the 94 excel. The Excel uses the front brakes the most, so are you sure you need to replace the rear brakes?

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 rear brake shoes


How to Replace Brake Shoes
(DIY Complexity: Moderate / DIY Time: 3.2 hours)

Parts:
1. Brake Shoe Set

Tools:
1. Combination Wrench Set
2. Floor Jack
3. Jack Stand Set
4. Mallet Hammer
5. Brake Spring Tool
6. Flat Head Screwdriver
7. Needle Nose Pliers
8. Tire Iron
9. Brake Resetting Gauge

Supplies:
1. Brake Cleaner

Steps:
Step 1 * Secure your vehicle on a level surface, making sure your car will not roll or lean when jacked up.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 * Break the lug nuts loose but do not remove. Lift up your vehicle using a floor jack.
o Tip: Using an aftermarket floor jack, instead of the original equipment (OE) jack, can make the job easier and safer. Verify the condition of the floor jack before use.

o Tip: Lug nuts fasten the wheel to the hub and may be on very tight. To gain more leverage, use a breaker bar to loosen the nuts.

Step 3 * Secure the vehicle with jack stands on both sides for safety before starting any work. Do not rely on the jack to hold the vehicle up while working.

Step 4 * Remove the lug nuts. Remove the wheels.
o Tip: Make sure the parking brake is released before removing the brake drum.

Step 5 * Remove the brake drum. If necessary, back off the star wheel adjuster.
o Tip: Hit the brake drum with a rubber mallet to break it loose from a rusted hub.

Step 6 * Clean the brake assembly using a“wet wipe method”. This method uses a spray bottle with water and detergent. Do not use compressed air to clean the brakes. Inspect the brake shoes for wear or damage.
o Tip: It is a good idea to leave one side assembled to use as a reference while you work on the other side.

Step 7 * Remove the primary and secondary brake shoe return springs from the anchor pin and brake shoes.
o Tip: The primary spring is connected to the front (primary) brake shoe and the secondary spring is connected to the rear (secondary) brake shoe.

Step 8 * Remove the adjuster cable and spring assembly. Remove the star adjusting screw and thread the adjuster all the way in.

Step 9 * Remove the front brake shoe retainer. Remove the front brake shoe and parking brake link.

Step 10 * Remove the parking brake lever from the rear brake shoe. Remove the rear brake shoe retainer and remove the rear brake shoe.
o Tip: Specialty brake tools are available to make brake shoe removal easier; but it is possible to remove the brake components with pliers.
o Tip: While you have the drum brake assembly apart, pry the outer seal away from the wheel cylinder and check for leaking brake fluid. If any brake fluid is leaking, replace or rebuild the wheel cylinder

Step 11 * Apply white lithium grease to the backing plate contact points.

Step 12 * Install the new brake shoes in the reverse order of removal. Be careful to keep the new brake shoes clean.

Step 13 * Inspect the brake drum and resurface or replace if necessary. Install the brake drum and adjust the brake shoes.
o Tip: There is a slot on the back of the backing plate usually blocked with a rubber grommet. To adjust the brakes, insert a screw driver into the slot and turn the star wheel adjuster. Spin the brake drum and stop adjusting when you feel a slight drag.

Step 14 * Install the wheels. Torque lug nuts to manufacturer’s specifications.

Step 15 * Lower vehicle and test drive to verify repairs.

Hope help with this (remember rated and comment this help).

The rear drum brakes:
  • Have internal shoes that expand against the brake drum (1126).
  • Are a single-anchor type.
  • Are actuated by one rear wheel cylinder (2262).
  • Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
  • Adjust rear brake shoes and linings (2200) automatically.
  • Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.
When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .

REAR BRAKES


i think your aware of how to change the brakes if im right and your problem is the rusted drum doesnt want to come off the only way to get the old drum off is to remove adjuster plug from behind drum dustshield and adjust the shoes so that there not even close to the braking area of the drum then try and wiggle the drum off of the assembly if it is not coming off then you need to use the old nylon hammer on the drum and i mean you must hit the drum from side to side trying by hand to wiggle the drum off its a tight fit and you need to strike the drum on the face not on the fins not wanting to damage with persistance and care and patience you will eventually be able to remove the drum to service brakes take care and good luck with it
