manner as for the master cylinder. Cleaning
and honing procedures are the same.
To reassemble, moisten the pistons and
cups with clean brake fluid and position the
spring in the center of the cylinder. Install
the rubber cups—flat side Out—followed by
the pistons—flat side in. Complete the as-
sembly with the push rods and protective
boots. The front wheel cylinder housings are
secured to the backing pkte by a threaded
anchor pin. Torque the pin to 65 ft. Ibs.

Parking Brake
ADJUSTMENT
The rear brakes do double duty as both wheel
brakes and parking brakes. Such an arrange-
ment makes proper adjustment of the park-
ing brakes dependent upon proper adjust-
ment of the wheel brakes. With the wheel
brakes correctly adjusted, remove the idler
return spring and loosen the locknut on the
convex side of the rear brake cable equalizer.
Next, tighten the adjustment nut against the
concave side of the equalizer until a 16 Ib
strand tension is achieved in the forward
brake cable. Tighten the locknut and attach
the idler return spring.

INSPECTION
Brake pads should be replaced when the lin-
ing is worn to the approximate thickness of
the metal part of the shoe.

expose the inboard (3) and outboard (4) brake pads
REPLACEMENT
1. Drain % of the brake fluid from the
master cylinder.
NOTE:
The insertion of the thicker re-
placement brakes will push the caliper pis-
tons back into their bores and the resulting
hydraulic action mil cause a full master
cylinder to overflow.
2. Raise and support the car and remove
the wheels. On 1984 and later models, use a
C-clamp to bottom the caliper piston in its
bore.
