Brake Drum and Shoe Inspection
• Remove and inspect each brake drum. The drum should not be cracked, warped or have excessive
scores or heat checks.
• Inspect the brake shoes. Shoes should not be distorted, cracked or have broken welds.
• Check the condition of the brake shoe linings. The brake shoe lining should not be glazed or soiled with
grease or brake fluid. There should be a minimum of 1/32-inch (0.8 mm) of usable lining remaining at
the thinnest point.

WARNING
• Use only approved replacement brake drums designed for your vehicle. For MC012C-BS00
transaxles, use CC P/N 102264701.
Brake Cluster Assembly Inspection
• Check each wheel cylinder (7) by pulling back the edge of each dust boot (Figure 6-1, Page 6-2 or
Figure 6-19, Page 6-21) . Brake fluid in the boot indicates a leaking wheel cylinder and should be
replaced. See Wheel Cylinder Replacement on page 6-19.
• Inspect the shoe hold-down parts and springs. Replace damaged items.
• If the brake adjusters (3) are frozen (requiring more than 65 in-lb (7.4 N·m) to turn freely), worn or
loose, replace the adjuster assemblies in pairs
(Figure 6-1, Page 6-2) . See Brake Shoe Adjuster
Replacement, Section 6, Page 6-21.
