Installation of the parking brake shoes can be tricky, so we provide the factory procedure, and an alternate procedure. Read through both procedures, then decide which procedure may work the best for you. If the first procedure you use doesnt work, try the other one.

  1. To install the parking brake shoe assemblies using the "factory procedure", perform the following:
    1. Fit the shoe and linings to the mounting plate. The primary and secondary shoes are identical. Make sure the operating lever and strut assembly is position on the wear shims, not down in the hole.
    2.  
    3. Use a suitable pair of pliers to install the shoe return spring.
    4.  
    5. Install the pins and hold-down springs by fitting to the spring to extend the pin head through the hole in the backing plate, then down into the slot.
    6.  

  2.  
  3. To install the parking brake shoe assemblies using the "alternate procedure", perform the following:
    1. Position the hold-down pin in the slot with a rubber band wrapped around it as shown in the accompanying figure
    2.
