This is a tedious, time-consuming job. You
can save yourself a lot of trouble by
buying a rebuilt master cylinder from y our dealer or parts supply house. The
small difference in price between a r ebuilding kit and a rebuilt part usually
makes it more economical, in terms of time and work, to buy the rebuilt part.
1. Remove the reservoir cover and diap hragm. Discard any brake fluid in the
reservoir.
2. Inspect the reservoir cover and diaphr agm for cuts, cracks, or deformation.
Replace any defective parts.
3. Depress the primary pist on and remove the lock ring.
4. Direct compressed air into the outle t at the blind end of the bore and plug
the other outlet to remove primary and secondary piston.
5. Remove the spring retainer and s eals from the secondary piston.
6. Clamp the master cylinder in a vise. Do not clamp it on the master cylinder
body. Use a pry bar to re move the reservoir.
7. Do not attempt to remove the quick take-up valve from the body. This valve
is not serviced separately.
8. Remove the reservoir grommets.
9. Inspect the master cylinder bore for corrosion. If corroded, replace the
master cylinder. Do not use any abrasive on the bore.
10. Reassemble, using new seals and gr ommets. Lubricate all parts with brake
fluid.
11. Install the reservoir grommets.
12. Install the reservoir.
13. Install the spring retainer and seals from the secondary piston.
14. Install primary and secondary piston.
15. Depress the primary pist on and install the lock ring.
16. Fill with brake fluid. Install the reservoir cover and diaphragm.
17. Bleed brake system.

4. Remove nuts and lockwashers that se
cure booster to firewall and remove
booster from engine compartment.
5. Install by reversing removal procedure. Make sure to check operation of stop
lights. Allow engine vacuum to build before applying brakes.

Avoid inhaling any dust from
any brake surface! When cleaning brake surfaces,
use a commercially available brake cleaning fluid.
1. Remove
2/3 of the brake fluid from the mast er cylinder. Raise the vehicle and
remove the wheel.
2. Place a C-clamp across the caliper, positioned on the brake pads. Tighten it
until the piston is forced into its bore.
3. Remove the C-clamp. Remove the bolt holding the brake hose to the caliper.
4. Remove the Allen head caliper mounting bolts. Inspect them for corrosion
and replace them if necessary. Remove the caliper.
To install:
5. Position the caliper with the brake pad installed and install Allen head caliper
mounting bolts. Mounting bo lt torque is 21-35 ft. lbs. (28-47 Nm.) for the
caliper.
6. Install the bolt holding the brake hos e to the caliper and tighten to 18-30 ft.
lbs. (24-40 Nm.).
7. Fill the master cylinder with brake fluid.
8. Install the wheels and lower the vehicle.
CAUTION - Before moving the vehicle, pump the brakes several times to seat
the brake pad against the rotor
OVERHAUL
Some vehicles may be equipped dual piston calipers. The procedure to
overhaul the caliper is e ssentially the same with t he exception of multiple
pistons, O-rings and dust boots.
1. Remove the caliper from the ve hicle and place on a clean workbench.
CAUTION - NEVER place your finger s in front of the pistons in an attempt to
catch or protect the pistons when applying compressed air. This could result in
personal injury!
Depending upon the vehicle, there are two different ways to remove the piston
from the caliper. Refer to the brake pad replacement procedure to make sure
you have the correct procedure for your vehicle.
2. The first method is as follows: a. Stuff a shop towel or a block of wood into the caliper to catch the piston.
b. Remove the caliper piston using co mpressed air applied into the caliper
inlet hole. Inspect the piston for scor ing, nicks, corrosion and/or worn or
damaged chrome plating. The piston mu st be replaced if any of these
conditions are found.

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.
