The springs are shown in their actual OE colors. Grease is shown pink. Do not allow anything (especially grease) to contaminate the friction surfaces.



Chock the front tires, support the rear axle, remove the wheel and drum.

Disassembly by hand (except step 10):
1) pull the autoadjuster lever (13) away from the screw (16) and turn the wheel to fully retract the screw into the nut (17).
2) Pull a shoe (9 or 20) away from the autoadjuster assembly (14-17) and remove the assembly.
3) Push the shoes (9 & 20) together and remove the lever (13) from the shoe (9).
4) Disconnect the cable (22) and spring (21) from the lever (13), and remove the spring (21) from the shoe (9).
5) Reach behind the FRONT of the plate (3) and hold the pin (28 ) while compressing & rotating the retainer (27) on the FORWARD shoe (less friction material). Remove the spring (19), retainers (18 ), & pin (28 ).
6) Pull the forward shoe (20) away from the plate (3) and swing it to relax & remove the return spring (24).
7) Remove the link bar assembly (7,25,26).
8 ) Remove the rear shoe retainer as in step 5, and its return spring as in step 6. Remove the cable (22) and guide (12). Remove the anchor guide plate (4).
9) Compress its spring (not shown) and slide the e-brake cable ferrule (not shown) out of the lever (8 ).
10) Use spreading snap ring pliers to open the C-clip (11) and remove the e-brake lever (8 ) from the shoe (9). Alternatively, hammer a wide flat-blade screwdriver against the tips to drive the clip back off the pin, then use a strong pick to pull it so it opens. Remove the spring washer (10) & e-brake lever (8 ) from the rear shoe (9, more friction material).
11) Remove both pushrods (6) and dust caps (on 5). (It may be necessary to hold the piston in the cylinder to get the cap past the limiter on the backing plate.) Fluid behind the dust caps indicates a fault in the autoadjuster mechanism or a leak in the wheel cylinder (5).

Clean ALL points of contact with a wire brush & brake cleaner, including inside the autoadjuster, and the piston faces. Lubricate ALL points of metal-to-metal contact (indicated in Pink) with either silicone grease or brake grease, including the edges of the shoes (9&20) & their slide pads on the backing plate (3).

.

Insert the e-brake lever (8 ) into a shoe (9) with LONGER friction material, then install the C-clip (11) over the spring washer (10) and crimp tightly in the pin's groove. While holding the piston in the cylinder, install the dust cap (2x).

Assembly is the reverse of removal steps 9-1. The e-brake levers go on the REAR shoes (more friction material).
