Pad ReplacementNLBR0029WARNING:
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.

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 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.

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.

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.

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.
Rotor repair limit:
26.0 mm (1.024 in)
