The brake shoes should be replaced when heat cracks are visible or approximately 2mm of lining thickness remains (thickness of lining material only). The brake shoes are always replaced as a set (both rear wheels). If necessary leave one side connected to use as a guide for this repair.
REMOVAL & INSTALLATION
See Figures 1 through 14
Manufacturing numbers on brake shoes face towards outside. Apply brake grease on wear points on the brake backing plate. Move the self-adjuster to fully released position before reinstalling the brake drum.
Refer to the Brake Drum, Removal & Installation procedures in this section and remove the brake drum.
Remove the tension pin clips, the two brake return springs and the brake shoes. If you are installing new shoes, back off the adjusters.
The upper and lower brake shoe return springs on the sedan are different and should not be interchanged. The upper spring is designed so that the spring coils are located on the outboard side of the shoe, while the lower spring is designed so that its coils are located on the inboard side of the shoe with the crossbar facing downward.
To install, reverse the removal procedure. Be sure to check the self-adjuster assembly for free and proper operation and the brake lining for grease spots (sand paper brake shoes lightly, if necessary). Bleed and adjust the brake system.
