P-11. Relining Wheel Brakes
When necessary to reline the brakes, the vehicle
should be raised so that all four wheels are free.
Remove the wheels and the hubs and drums which
will give access to the brake sh oes, Fig. 288.
Install wheel cylinder clamps or k eepers to retain
the wheel cylinder pistons in place and prevent
leakage of brake fluid while repl ac ing the shoes .
Turn all eccentrics to the lowest side of the cam
and then remove the brake shoe return springs.
If e quipped with anchor pins remove the anchor
pin nuts, lock washers a nd anchor pins from the
backing plate.
Brake shoes may be distorted by improper lining
installation and linings should be ground true after
installation on the shoes. For this reason it is rec·
ommended that new or replacement shoe and lining
assemblies be installed.
Inspect the oil s ea ls in the wheel hubs. If the con -
dition of any oil seal is doubtful, replace it . Install
the oil seal c arefully to pr event damage to s eali ng
surfaces.
Ins tall the brake shoes on the brake backing plates
and remove the wheel cylinder clamps.
Note: On some vehicles, the iining on the forward
shoe is longer than the lining on t he reverse shoe.
Inst all the e ccentrics and the brake shoe retainin g
springs.
Should a brake drum be rough and scored, it may
be reconditioned by grinding or turning in a lathe.
Do not remove more than .030" [. 762 mm.] thick-
ness of metal (.060
11
- 1.52 mm. - overall diameter) ..
If a drum is reconditioned in this manner, either the
correct oversize lining or shoe must be installed or a
shim equal in thickness to the me tal removed must
be placed between the lining and shoe so that the
arc of t he lin ing will be the same as that of the
drum.
