Additional Adjustment Information
After the brake and hub assemblies have been reassembled and the hub bearings have been adjusted properly, a Major Brake Adjustment is required. This is described on Page 5 of this guide (page 85 of the Shop Manual). If you do not have the Heel / Toe Adjustment Tool, MT-34-B (Special Tool), follow these procedures.
1. Reinstall the brake drums using the three 3/16" - 16 x 1 1/4" flathead screws. Use a good anti-seize compound or a waterproof grease on the threads of the flathead screws. Be sure the drums are centered. The flathead screws should be more than finger tight, but do not over tighten them. They are only used to hold the brake drum in place and centered until the wheel is mounted and the lug nuts are tightened.
2. To adjust the heel of the shoe, face the back (Inside) of the brake support (backing plate) and turn the Anchor Bolts until the bolt’s arrow or center punch marks, point toward each other. Then turn the right hand Anchor Bolt counter-clockwise and the left Anchor Bolt clockwise. In doing so, the heel of the shoe will move downward and outward toward the drum.
3. Looking through the drum inspection hole, place a .006 feeler gauge between the shoe close to the heel and the drum shoe surface and adjust heel clearance to .006 for the front and rear brake shoes.
4. To adjust the toe of the shoe, face the back (Inside) of the brake support (backing plate) use the two ¾ inch nuts located a the "ten o'clock" and "two o'clock" positions of the brake support (backing plate). These nuts move the brake shoe toe adjusting cam. To adjust the clearance of either brake shoe, turn the top of the nut toward the opposite nut to increase toe clearance; or turn the top of the nut away from the opposite nut to decrease clearance.
5. Move the inspection hole up to the shoe’s toe. Looking through the drum inspection hole, place a .012 feeler gauge between the shoe and the drum shoe surface and adjust toe to .012.
6. Recheck the clearance of both adjustments and readjust as needed.
Adjusting brake pedal travel and dealing with routine wear of the brake shoe linings is done with a Minor Brake Adjustment as described on Page 4 of this guide (Page 84 of the Shop Manual).
