Master Cylinder/Brake Booster
Removal/lnstallation
1, Disconnect the brake fluid level switch connectors.
2. Remove the reservoir cap from the master cylinder.
3. Remove the brake fluid from the master cvlinder
reservoir with a syringe.
4. Disconnect the brake lines from the master cylinder.
To prevent spills, cover the line joints with rags or
shop towels.
5. Remove the master cylinder mounting nuts and
wasners.
6. Remove the master cylinder from the brake booster.
CAUTION: Be careful not to bend or damage the
brake lines when removing the master cylinder.
Do not spill brake fluid on the vehicle; it may dam.
age the paint; it brake fluid does cont.ct the paint,
wash it oft immediately with water.
7. Disconnect the vacuum hose from the brake booster.
8. Remove the cotter pin and clevis pin from the clevis.
Do not disconnect the clevis by removing it from
the operating rod of the brake booster. lf the clevis
is loosened, adjust the pushrod length before
installing the brake booster (see page 19-15).

reverse order of removal, and note these items:
. When connecting the brake lines, make sure that
there is no interference between the brake lines
and other parts.
. Be careful not to bend or damage the brake lines
when installing the master cylinder.
. lf replacing the master cylinder or brake booster,
check and adjust the pushrod clearance before
installing the master cylinder (see page 19-14).
Fill the master cylinder reservoir, and bleed the
brake system (see page 19-7).
After installation, check the brake pedal height and
brake pedal free play (see page 19-5), and adjust if
necessary.

piston clearance is 0 mm. However. if the clearance
between the gauge body and adjusting nut is 0 mm,
the pushrod-to-piston clearance is 0.4 mm (0.02 in)
or more. Therefore it must be adjusted and
recheck€d.
lf clearance is incorrect, loosen the star locknut, and

Brake Booster Inspection
FunctionalTest
1. With the engine stopped, press the brake pedal sev-
eral times to deplete the vacuum reservoir. thenpress the pedal hard, and hold it for 15 seconds. lf
the pedal sinks, either the master cylinder is
bypassing internally, or the brake system (master
cylinder, lines, modulator, proportioning valve. or
caliper) is leaking.
2. Start the engine with the pedal pressed. lf the pedal
sinks slightly. the vacuum booster is operating nor-
mally. lf the pedal height does not vary, the booster
or check valve is faultv.
3. With the engine running, press the brake pedal light-
ly. Apply just enough pressure to hold back auto-
matic transmission creep. lf the brake pedal sinks
more than 10 mm (3/8 in.) in three minutes, the mas-
ter cylinder is faulty. A slight change in pedal height
when the Ay'C compressor cycles on and off is nor-
mal. (The Ay'C compressor load changes the vacuum
available to the booster.)
Leak Test
1.Press the brake pedal with the engine running, then
stop the engine. lf the pedal height does not vary
while pressed for 30 seconds, the vacuum booster is
OK. lf the pedal rises, the booster is faulty.
With the engine stopped, press the brake pedal sev-
eral times using normal pressure. When the pedal is
first pressed. it should be low, On consecutive appli-
cations, the pedal height should gradually rise. lf thepedal position does not vary. check the booster
check valve.
Boostor Chock Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Start the engine, and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve. and retest.

Inspection/Torque Specif ications
1. Inspect the brake hoses for damage, deterioration, leaks, interference, and twisting
2. Check the brake Iines for damage, rusting, and leakage. Also check for bent brake lines.
3. Check for leaks at hose and line joints and connections, and retighten if necessary.
4. Checkthe master cylinder, proportioning control valve. and ABS modulator unit for damage and leakage.
NOTE: Replace the brake hose clip whenever the brake hose is serviced.
