CAUTION
- Brake shoes may contain asbest os, which has been determined to
be a cancer causing agent. Never clean the brake surfaces with compressed
air! Avoid inhaling any dust from any brake surface! When cleaning brake
surfaces, use a commercially available brake cleaning fluid.
1. Raise and support the car. Remove t he wheel. Remove the brake shoes by
following the Brake Shoe R eplacement procedure.
2. Remove dirt from ar ound the wheel cylinder inle t and pilot. Disconnect the
inlet tube.
3. Using 2 awls,
1/8 in. (3mm) in diameter, or J29839, remove the wheel
cylinder retainer. Insert the awls in to the access slots between the wheel
cylinder pilot and retainer. Simultaneous ly, bend both tabs away from each
other. Remove the wheel cylinder.
To install:
4. Place wheel cylinder into position and place a block of wood between it and
the axle flange. Install a new retainer over the end of the wheel cylinder.
Using a 1
1/8 in. 12-point socket with an extensi on, drive the new retainer into
position.
5. Connect the inlet tube and torque 120-280 inch lbs. (13.6-20 Nm). Complete
installation by reversing the remova l procedure. Bleed the brakes.
OVERHAUL
Wheel cylinder overhaul kits may be available, but often at little or no savings
over a reconditioned wheel cylinder. It often makes sense with these
components to substitute a new or re conditioned part instead of attempting an
overhaul.
If no replacement is availabl e, or you would prefer to overhaul your wheel
cylinders, the following procedure may be used. When rebuilding and installing
wheel cylinders, avoid getting any cont aminants into the system. Always use
clean, new, high quality brake fluid. If di rty or improper fluid has been used, it
will be necessary to drain the entire syst em, flush the system with proper brake
fluid, replace all rubber components , then refill and bleed the system.
1. Remove the wheel cylinder from the vehicle and place on a clean
workbench.
2. First remove and discard the old r ubber boots, then withdraw the pistons.
Piston cylinders are equipped with seals and a spring assembly, all located
behind the pistons in the cylinder bore.

3. Remove the remaining inner com ponents, seals and spring assembly.
Compressed air may be useful in removing these components. If no
compressed air is available, be VERY careful not to score the wheel cylinder
bore when removing parts from i t. Discard all components for which
replacements were supplied in the rebuild kit.

WARNING - Never use a mineral-based solvent such as gasoline, kerosene or
paint thinner for cleaning purposes . These solvents will swell rubber
components and quickly deteriorate them.
5. Allow the parts to air dry or use compressed air. Do not use rags for
cleaning, since lint will rema in in the cylinder bore.
6. Inspect the piston and replace it if it shows scratches.

7. Lubricate the cylinder bore and s eals using clean brake fluid.
8. Position the spring assembly.
9. Install the inner seals, then the pistons.

cancer causing agent. Never clean the brake surfaces with compressed air!
Avoid inhaling any dust from any brake surface! When cleaning brake surfaces,
use a commercially available brake cleaning fluid.
1. To remove the brake caliper, refer to the Rear Caliper Removal procedure.
2. Remove the brake pads from the calipers. Remove the sleeves from the
mounting bolts and the bushi ngs from the caliper.
3. Using a small screwdriver, remove the 2-way check valve from the end of
the piston. Clean and check the valve for leakage.
If leakage is noted, the caliper must be overhauled.

4. Position the brake pads
into the caliper. Lubricate and install new bushings,
sleeves and check valve.
5. When installing the inner brake pad, make sure that the D-shaped tab of the
pad engages with the D-shaped notch of the piston, as illustrated.
6. Upon installation of the inner pad, make sure that the wear sensor of the pad
is at the leading edge of the shoe during forward wheel rotation. Slide the
metal edge of the pad under the ends of the dampening spring and snap the
pad into position against the piston.
7. Install the outer pad and caliper. Afte r installing the caliper, apply the brakes,
then bend the ears of the out er pad against the caliper and ensure that there
is no excessive clearance.
