OPERATION
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.
AIR TIGHT
 Idle the engine for 1 minute to apply vacuum to the brake booster,
and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric pressure. Check that the clearance between brake
pedal and dash lower panel gradually increases (A → B → C) each
time the brake pedal is depressed during this operation.
 Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal
for 30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due
to the brake system operation.

BRAKE MASTER CYLINDER
 The piston may drop off when pulled out strongly. Never hold the piston. Hold the cylinder body
when handling the master cylinder assembly.
INSTALLATION
CAUTION:
Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
Note the following, and install the reverse order of removal.
 Never depress the brake pedal after the master cylinder assembly is removed.
 Apply PBC (Poly Butyl Cuprysil) silicone-based grease to the
brake booster [see (A) in the figure] when installing the master cyl-
inder assembly to the brake booster.
 The piston of the master cylinder assembly is exposed. Never
damage it when handling the master cylinder and check that no dirt
and dust are present on the piston before installation. Clean it with
new brake fluid if necessary.
 The piston may drop off when pulled strongly. Never hold the pis-
ton. Hold the cylinder body when handling the master cylinder
assembly.
 Temporarily tighten the brake tube flare nut to the master cylinder
assembly by hand. Then tighten it to the specified torque with a
crowfoot and torque wrench. Refer to BR-19, "
FRONT : Exploded View".
CAUTION:
Never scratch the flare nut and the brake tube.
 After installation, perform the air bleeding. Refer to BR-10, "
Bleeding Brake System".
CAUTION:
Never reuse drained brake fluid.
Disassembly and AssemblyINFOID:0000000003811196
DISASSEMBLY
CAUTION:
 Never disassemble the cylinder body.
 Remove the reservoir tank if necessary.
1. Fix the master cylinder assembly to a vise.
CAUTION:
Always set copper plates or cloth between vise when fixing the cylinder body to a vise. Never
overtighten the vise.
2. Remove the reservoir tank mounting pin with a pin punch.
3. Remove the reservoir tank and grommet from the cylinder body.
CAUTION:
Never drop the removed parts. The parts must not be
reused if they are dropped.

CAUTION:
 Never use mineral oil such as gasoline or light oil.
 Never reuse the grommets.
2. Install the reservoir tank to the cylinder body.
CAUTION:
 Never drop the parts when installing. The parts must not be reused if they are dropped.

INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. With a handy vacuum pump, apply vacuum pressure of −66.7
kPa (−500 mmHg, −19.70 inHg, –0.667 bar) to the brake
booster.
2. Check the output rod length (A).
Input Rod Length Inspection
1. Loosen the lock nut (1) and adjust the input rod (2) to the speci-
fied length (B).
2. Tighten the lock nut to the specified torque.
INSPECTION AFTER INSTALLATION
Operation
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower pane decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.

FRONT DISC BRAKE
4. Apply brake fluid to piston (1). Push piston into cylinder body by
hand and push piston boot (2) piston-side lip into the piston
groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
5. Apply rubber grease to bushing, install bushing to sliding pin.
6. Apply rubber grease to sliding pins and sliding pin boots, install
sliding pins and sliding pin boots to torque member.
7. Install the cylinder body to the torque member and tighten the
sliding pin bolts to the specified torque.

INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of the cylinder for rust, wear, cracks or damage. Replace if necessary.
CAUTION:
Always clean with new brake fluid. Never clean with mineral oil such as gasoline and light oil.
Torque Member
Check the torque member for rust, wear, cracks or damage. Replace if necessary.
Piston
Check the surface of the piston for rust, wear, cracks or damage. Replace if necessary.
CAUTION:
A piston sliding surface is plated. Never polish with sandpaper.
Sliding Pin, Sliding Pin Boot and Bushing
Check the sliding pins, sliding boot and bushing for rust, wear, cracks or damage. Replace if necessary.
INSPECTION AFTER INSTALLATION

PEDAL VIBRATION OR ABS OPERATION SOUND OCCURS
Diagnosis ProcedureINFOID:0000000003766856
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
 When shifting gears
 When driving on slippery road
 During cornering at high speed
 When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
 When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1.SYMPTOM CHECK 1
Check that there are pedal vibrations when the engine is started.
Do vibrations occur?
YES >> GO TO 2.
NO >> Inspect the brake pedal.
2.SYMPTOM CHECK 2
Check that there are ABS operation noises when the engine is started.
Do the operation noises occur?
YES >> GO TO 3.
NO >> Perform self-diagnosis.
3.SYMPTOM CHECK 3
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> Normal

NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003766858
Symptom Result
Slight vibrations are felt on the brake pedal and the operation noises occur, when ABS is activated.
This is a normal condi-
tion due to the ABS acti-
vation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and
just after the vehicle starts.This is a normal, and it is
caused by the ABS op-
eration check.
