brakes are asbestos free. However, there is the possibility
that the original brakes were replaced with aftermarket parts containing
asbestos. Since this possibility exists, all brake parts should be handled as if
they contain asbestos. Refer to appendix C for recommended handling
precautions.
When replacing brake components, it is recommended
to replace both left and right side at the same time.
6. Raise the rear of the vehicle and support with jack
stands.
7. Remove the rear wheel and brake drum.
8. Remove Springs (1, 6, 12).
9. Remove park brake cable (10), cam (9) and guide
(15).
10. Remove brake shoe hold down cups, springs and
pins (4).
11. Remove the brake shoes (5), adjustor (7, 8), and
park brake link and spring (2, 3).
12. Pry the horseshoe clip (13) and remove the park
brake arm (11). Discard the horseshoe clip.
DO NOT reuse the horseshoe clip. The clip
is damaged when it is removed and may
fail if it is reinstalled. This will result in
failure of the brake system.
13. Reassemble the brake in reverse order.
•
Use a new horseshoe clip (13)
•
Thoroughly clean the adjusting nut (8) threads and
apply a light film of high temperature grease to the
threads.

Before installing the brake drum, depress the brake
pedal and check to be sure that the auto adjust
mechanism is functioning properly.
14. Repeat procedure for other side of vehicle.
Preliminary brake adjustment:
With the brake drum and wheel installed, remove the
plug from the adjuster access hole.
While rotating the wheel, using brake spoons, rotate the
star wheel (8) until the brake is locked and the wheel
cannot be turned by hand.
Loosen the star wheel (8) just enough so that the wheel
rotates with no brake drag.
Repeat for other side of vehicle.
Test drive the vehicle.
