INSPECTION



For a quick, semi-accurate inspection of the rear brake pads, look through the hole in the top of the caliper (brake cylinder). This inspection will quickly give you a general idea of the condition of the brake pads; if you are in doubt, the caliper and brake pads themselves will have to be removed for proper inspection.

REMOVAL & INSTALLATION



1971-81 Models

See Figure 1


WARNING
Clean, high quality brake fluid is essential to the safe and proper operation of the brake system. You should always buy the highest quality brake fluid that is available. If the brake fluid becomes contaminated, drain and flush the system, then refill the master cylinder with new fluid. Never reuse any brake fluid. Any brake fluid that is removed from the system should be discarded.

  1. Remove the brake pads, pad guide plates, anti-rattle springs and the pad support plates.
  2.  
  3. Inspect the pads for wear. If the grooves are worn out of the pads, they will require replacement. Check the pad thickness against the specifications given in the Brake Specifications chart later in this section. Check all guides and springs for any wear or deformation.
