BRAKE BOOSTER ASSEMBLY
ON±VEHICLE INSPECTION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly.
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is airtight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed. If there is no
change in the pedal reserve travel after holding the pedal
for 30 seconds, the booster is airtight.

REPLACEMENT
1. REMOVE FRONT WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if not within specifi-
cation.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE CLIP, 2 PINS AND ANTI±RATTLE SPRING
4. REMOVE 2 PADS WITH 4 ANTI±SQUEAL SHIMS
NOTICE:
The anti±rattle spring and clip can be used again provided
that they have sufficient rebound, no deformation, cracks
or wear, and have had all rust, dirt and foreign particles
cleaned off.
5. CHECK DISC THICKNESS AND RUNOUT
(See page BR±30)
6. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti±squeal shims must be
replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a monkey wrench handle or
equivalent.
HINT:
Tape the monkey wrench handle before use.
Always change the pad on one wheel at a time as there
is a possibility of the opposite piston flying out.
If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.
(c) Install the 4 anti±squeal shims to new pads.
