1. Disconnect the brake switch connector, loosen thebrake switch locknut, and back oll the brake switchuntil it is no longer touching the brake pedal.
2. Turn up the jloor mat, and measure the pedal heightfrom the lett srde center of the pedal pad.

3. Loosen the pushrod locknut, and screw the pushrod
in or out with pliers until the standard pedal height
from the floor is reached. After adjustment, tighten
the locknut firmly. Do not adjust the pedal height
with the pushrod depressed.

Screw in the brake switch until its plunger is fully
depressed (threaded end touching the pad on thepedal arm). Then back off the switch 1/4 turn tomake 0.3 mm (0.01 in) of clearance between thethreaded end and the pad. Tighten the locknut firm-ly. Connect the brake switch connector.
CAUTION: Make sure that the brake lights go oflwhen the pedal is released.
5. Check the brake pedal free play as described below.
Pedal Free Play
1. Stop the engine, and inspect the play on the pedal
pad by pushing the pedal by hand.
Free Play: 1 - 5 mm {l/16 - 3/16 in)
2. lf the pedal free play is out of specification, adjustthe brake switch. tf the pedal free play is insuffi_cient, it may result in brake drag.

Tighten the adjusting nut until the rear wheels drag
slightly when turned.
7.
Release the parking brake lever fully, and check that
the rear wheels do not drag when turned. Readjust
if necessary.
Make sure the parking brakes are fully spplied when
the parking brake lever is pulled up fully.
Install the cap onto the parking brake cable end, and
reinstall the rear console.

NOTE: lf the clearance between the gauge body
and adjusting nut is 0.4 mm (0.02 in), the pushrod-
to-piston clearance is 0 mm. However, if the clear-
ance 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
rechecked.
lf clearance is incorrect, loosen the star locknut and
turn the adjuster in or out to adjust.
NOTE:
. Adjust the clearance while the specified vacuum
is applied to the booster.
. Hold the clevis while adjusting.
Tighten the star Iocknut securely.
Remove the special tool.

Brake Booster Inspection
Functions Tgst
1. With the engine stopped, depress the brake pedal
several times to deplete the vacuum reservoir, then
depress the pedal hard and hold it for 15 seconds. ll
the pedal sinks, either the master cylinder is
bypassing internally; or the brake system (master
cylinder, lines, modulator proportioning valve, orcaliper) are leaking.
Start the engine with the pedal depressed. lf thepedal sinks slightly, the vacuum booster is operat-
ing normally. lf the pedal height does not vary, the
booster or check valve is faulty.
With the engine running, depress the brake pedal
lightly. Apply just enough pressure to hold back
automatic transmission creep, lf the brake pedal
sinks more than 25 mm (1.0 in.) in three minutes,
the master cylinder is faulty. A slight change inpedal height when the A,,/C compressor cycles on
and off is normal. (The A/C compressor load
changes the vacuum available to the booster.)
Leak Test
1. Depress the brake pedal with the engine running,
then stop the engine. lf the pedal height does not
vary while depressed for 30 seconds, the vacuum
booster is OK. lf the pedal rises, the booster is
fau lty.
2. With the engine stopped, depress the brake pedal
several times using normal pressure. When thepedal is first depressed, it should be low. On con-
secutive applications, the pedal height should grad-
ually rise. lf the pedal position does not vary, check
the booster check valve.
Boostor Ch€ck Valve T6st
1. Disconnect the brake booster vacuum hose at the
booster,
Start the engine and let it idle. There should be vac-
uum available. It no vacuum is available. the check
valve is not working properly. Replace the brake
booster vacuum hose and check valve, and retest.
