1. Loosen lock nut and adjust pedal free height by turning brake
booster input rod. Then tighten lock nut.
2. Check pedal free play.
Make sure that stop lamps go off when pedal is released.
3. Check brake pedal’s depressed height while engine is running.
If lower than specification, check brake system for leaks, accu-
mulation of air or any damage to components (master cylinder,
wheel cylinder, etc.), then make necessary repairs.

On-vehicle ServiceNLBR0023OPERATING CHECKNLBR0023S011. 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.
SBR365AA
AIRTIGHT CHECKNLBR0023S021. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. The pedal should go further
down at the first time, and then it should gradually rise there-
after.
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.

+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
booster removal.

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.

Clean brake pads with a vacuum dust collector to minimize the
hazard of airborne particles or other materials.
CAUTION:
+When cylinder body is open, do not depress brake pedal
because piston will pop out.
+Be careful not to damage piston boot or get oil on rotor.
Always replace shims when replacing pads.
+If shims are rusted or show peeling of the rubber coat,
replace them with new shims.
+It is not necessary to remove connecting bolt except for
disassembly or replacement of caliper assembly. In this
case, suspend cylinder body with wire so as not to stretch
brake hose.
+Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to“Brake Burnishing Procedure”,“ON-VEHICLE
SERVICE”, BR-7.

3. Open cylinder body upward. Then remove pad with retainers,
inner and outer shims.
Standard pad thickness:
11 mm (0.43 in)
Pad wear limit:
2.0 mm (0.079 in)
Carefully monitor brake fluid level because brake fluid will
return to reservoir when pushing back piston.

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.

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.
InspectionNLBR0033CALIPERNLBR0033S01Cylinder BodyNLBR0033S0101+Check 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.

RunoutNLBR0033S02021. 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:
0.08 mm (0.0031 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).
ThicknessNLBR0033S0203Thickness variation (At least 8 positions):
Maximum 0.02 mm (0.0008 in)
If thickness variation exceeds the specification, turn rotor with on-
car brake lathe.
