DisassemblyNJBR0136Disassemble the components, referring to the “Component”, then
remove vacuum pump.
CAUTION:
Do not disassemble vacuum pump. (Do not loosen three M6
bolts.)
AssemblyNJBR0127Install all parts to cylinder head rear cover as follows.
1. Install vacuum pump.
2. Install chain guide temporarily.
Adjust the chain guide position by the method explained in step
5.
SBR614E
3. Install rear cam sprocket.
Installation direction of sprocket is not specified.
Insert 2 thickness gauges [3.0 mm (0.118 in)] between cover
and rear cam sprocket (shown in the figure). Insert 2 bolts [M6,
thread length: 35 - 40 mm (1.38 - 1.57 in)] into sprocket to
retain it to cover.
Use thickness gauges [3.0 mm (0.118 in)] for chain alignment
between vacuum pump sprocket and cam sprocket.
4. Attach drive chain to rear cam sprocket and vacuum pump
sprocket.
5. Tighten chain guide installation bolt while pressing chain guide

Pad ReplacementNJBR0029WARNING:
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 drums or rotors, after replacing pads or linings,
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 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.

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)
