On-vehicle ServiceNJBR0023OPERATING CHECKNJBR0023S011. Stop engine and depress brake pedal several times. Check
that pedal stroke does not change.
2. Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECKNJBR0023S021. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. The pedal should go further
down the first time, and then it should gradually rise thereaf-
ter.
2. Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change
after holding pedal down for30 seconds.

RemovalNJBR0024CAUTION:
Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
Be careful not to deform or bend brake pipes, during
removal of booster.
SBR208E
InspectionNJBR0025OUTPUT ROD LENGTH CHECKNJBR0025S011. Apply vacuum of −66.7 kPa (−667 mbar, −500 mmHg, −19.69
inHg) to brake booster with a handy vacuum pump.
2. Add preload of 19.6 N (2 kg, 4.4 lb) to output rod.
3. Check output rod length.
Specified length:
10.275 - 10.525 mm (0.4045 - 0.4144 in)
BRAKE BOOSTER
On-vehicle Service
BR-20

InstallationNJBR0026CAUTION:
Be careful not to deform or bend brake pipes, during
installation of booster.
Replace clevis pin if damaged.
Refill with new brake fluid “DOT 4”.
Never reuse drained brake fluid.
Take care not to damage brake booster mounting bolt
thread when installing. Due to the acute angle of
installation, the threads can be damaged with the dash
panel.
SBR237EA
1. Before fitting booster, temporarily adjust clevis to dimension
shown.
2. Fit booster, then secure mounting nuts (brake pedal bracket to
master cylinder) lightly.
3. Connect brake pedal and booster input rod with clevis pin.
4. Secure mounting nuts.
Specification:
13 - 16 N·m (1.3 - 1.6 kg-m, 9 - 12 ft-lb)
5. Install master cylinder. Refer to “Installation” in “MASTER
CYLINDER”, BR-19.
6. Bleed air. Refer to “Bleeding Brake System”, BR-8.

1. Remove master cylinder reservoir cap.
2. Remove pin bolt.
3. Open cylinder body upward. Then remove pad with retainers,
inner and outer shims.
Standard pad thickness:
11 m m ( 0 . 4 3 i n )
Pad wear limit:
2.0mm(0.079in)
Carefully monitor brake fluid level because brake fluid will
return to reservoir when pushing back piston.
SBR979B
RemovalNJBR0031WARNING:
Clean brake pads with a vacuum dust collector to minimize the
hazard of airborne particles or other materials.
Remove torque member fixing bolts and connecting bolt.
It is not necessary to remove connecting bolt except for dis-
assembly or replacement of caliper assembly. In this case,
suspend caliper assembly with wire so as not to stretch brake
hose.
SBR772
DisassemblyNJBR0032WARNING:
Do not place your fingers in front of piston.
CAUTION:
Do not scratch or score cylinder wall.
1. Push out piston with piston boot with compressed air.
2. Remove piston seal with a suitable tool.
InspectionNJBR0033CALIPERNJBR0033S01Cylinder BodyNJBR0033S0101Check inside surface of cylinder for score, rust, wear, damage
or presence of foreign materials. If any of the above conditions
are observed, replace cylinder body.
Minor damage from rust or foreign materials may be eliminated
by polishing surface with a fine emery paper. Replace cylinder
body if necessary.

CAUTION:
Use brake fluid to clean. Never use mineral oil.
PistonNJBR0033S0102CAUTION:
Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign materials are stuck to sliding
surface.
Check piston for score, rust, wear, damage or presence of foreign
materials. Replace if any of the above conditions are observed.
Slide Pin, Pin Bolt and Pin BootNJBR0033S0103Check for wear, cracks or other damage. Replace if any of the
above conditions are observed.
ROTORNJBR0033S02Rubbing SurfaceNJBR0033S0201Check rotor for roughness, cracks or chips.
SBR219C
RunoutNJBR0033S02021. Secure rotor to wheel hub with at least two nuts (M12 x 1.25).
2. Check runout using a dial indicator.
Make sure that wheel bearing axial end play is within the
specifications before measuring. Refer to AX section
(“Front Wheel Bearing”, “ON-VEHICLE SERVICE”).
Maximum runout:
0.07 mm (0.0028 in)
3. If the runout is out of specification, find minimum runout posi-
tion as follows:
a. Remove nuts and rotor from wheel hub.
b. Shift the rotor one hole and secure rotor to wheel hub with
nuts.
c. Measure runout.
d. Repeat steps a. to c. so that minimum runout position can be
found.
4. If the runout is still out of specification, turn rotor with on-car
brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or
equivalent).
ThicknessNJBR0033S0203Thickness variation (At least 8 positions):
Maximum 0.01 mm (0.0004 in)
If thickness variation exceeds the specification, turn rotor with on-
car brake lathe.
Rotor repair limit:
20.0 mm (0.787 in)
