  1. Remove rear wheel and brake drum.
  2.  
  3. Remove the lower pressed metal spring clip, the shoe return spring (the large one piece spring between the two shoes), and the two shoe hold-down springs.
  4.  
  5. Remove the shoes and adjuster as an assembly. Disconnect the parking brake cable from the lever, remove the spring between the shoes and the lever from the rear (trailing) shoe. Disconnect the adjuster retaining spring and remove the adjuster, turn the star wheel in to the adjuster body after cleaning and lubricating the threads.
  6.  
  7. The wheel cylinder may be removed for service or replacement, if necessary.
  8.  
  9. Clean the backing plate. Install the wheel cylinder if it was removed. Lubricate all contact points on the backing plate, anchor plate, wheel cylinder to shoe contact and parking brake strut joints and contacts. Install the brake shoes after attaching the parking brake, lever and adjuster assemblies. Install the holddown and return springs.
  10.  
  11. Pre-adjustment of the brake shoe can be made by turning the adjuster star wheel out until the drum will just slide on over the brake shoes. Before installing the drum make sure the parking brake is not adjusted too tightly, if it is-loosen, or the adjustment of the rear brakes will not be correct.
  12.  
  13. If the wheel cylinders were serviced, bleed the brake system. The brake shoes are then adjusted by pumping the brake pedal and applying and releasing the parking brake, Adjust the parking brake stroke. Road test the car.

Fig. Fig. 9: Installing upper return spring - 1992 Colt

  1. Using brake spring pliers, remove the spring connecting the two shoes and the spring connecting the right side shoe to the adjuster strut.
  2.  
  3. Remove the shoe hold-down spring on either side by first depressing slightly and then twisting the retaining cap. (There is a common brake tool that is designed to make this almost effortless.) The tangs on the retaining post must line up with the notches in the cap; release the cap in this way and then remove the cap, spring, and spring seat. Remove shoe retaining spring with the pliers.
  4.  
  5. Remove the leading (right side) shoe.
  6.  
  7. Remove the other shoe then disconnect the parking brake cable at the shoe. It's easier to disconnect the cable with the shoe removed from the backing plate but can be done otherwise if you wish.
  8.  
  9. If the parking brake cable is to be removed entirely, you can now remove the snapring at the backing plate and pull the end of the cable through.
  10.  
  11. To install, first grease the surfaces of the shoe that will contact the backing plate (this means the side edge of the shoe, NOT the friction surface), the backing plate contact points, and the working surfaces of the anchor plate and wheel cylinder pistons. Use a silicone based grease; not all lubricants are appropriate.
  12.  
  13. Assemble hold down pins and springs and install the parking brake cable to the shoe. Install the shoe and secure the spring pin with the push-and-twist motion. (This can become a three-handed job; an assistant may be required.).
  14.  
  15. Install the other shoe and secure it.
  16.  
  17. Install the adjusting mechanism and springs, making sure the springs are in the correct position. It is quite possible to install the springs backwards; this will cause impaired function and noise.When installing the shoe-to-shoe and shoe-to-strut springs, set the adjuster lever so the ratchet is locked in the fully released direction.
  18.  
  19. Double check the placement and installation of all components. Everything must be accurately placed and securely fastened.
  20.  
  21. Use the adjuster to set the brakes to the correct diameter. Use an accurate measuring device to measure the outer diameter of the brake shoes. This measurement must be set correctly; otherwise either the drum will not go over the shoes or the adjustment will be too loose. Correct measurement is 179.0-179.5mm.
  22.  
  23. Install the brake drum as described above.
  24.  
  25. Install the wheels. Make sure you depress the brake pedal repeatedly to fully adjust the self-adjusters before operating the vehicle. Operate the vehicle at very low speed in both forward and reverse gears, pumping the brake pedal repeatedly. Bring the car to a full stop and operate the parking brake several times. Pedal feel should be normal, but the car should roll freely (with no drag) when the pedal is released. If any condition is abnormal, the brake adjustment and/or components must be investigated and corrected.

  21. Remove the brake cable snapring and remove the cable.
  22.  
  23. Inspect all parts for wear or damage. Heat damage is a problem common to brake systems. Sign of heat damage are bluing and cracking. It's a good idea, when replacing brake shoes, to replace all the brake hardware, i.e., springs and clips.
  24.  

Never replace shoes on one side only! Replace both sets of shoes at the same time.

  1. Assembly the parking brake and adjuster assemblies on the brake shoes. Install the brake shoes and hold-downs. Connect the return springs. Apply a small amount of silicone based grease to the contact pads of the backing plate before installing the shoes. When installing the shoe-to-shoe spring and shoe-to-strut spring, set the adjuster lever all the way back against the shoe. When everything is assembled, pump the pedal several times and adjust the brakes.
