BR-22
FRONT DISC BRAKE
Revision: August 20072004 QX56
WAR NIN G:
Clean dust on cylinder body and brake pads with a vacuum dust collector to minimize the hazard of
airborne particles or other materials.
CAUTION:
While removing cylinder body never depress brake pedal because piston will pop out.
It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of cylinder body. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
Do not damage piston boot.
Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft
pedal occurs at very low mileage. Refer to BR-25, "
BRAKE BURNISHING PROCEDURE" .
Removal and Installation of Brake PadEFS003PP
REMOVAL
1. Remove wheel and tire using power tool.
2. Remove master cylinder reservoir cap.
3. Remove lower sliding pin bolt using power tool.
4. Suspend cylinder body with a wire and remove pads, shims and retainers from torque member.
INSTALLATION
1. Apply Molykote AS880N grease between brake pad plate and shim, then attach shims to brake pads.
Refer to MA-10, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
2. Attach pad retainer to torque member, then install brake pad and
shim assemblies.
CAUTION:
When attaching pad retainer, attach it firmly so that it is
flush with torque member, as shown.
3. Push pistons into cylinder body.
NOTE:
Using a disc brake piston tool (commercial service tool), etc.,
makes it easier to push in piston.
CAUTION:
By pushing in piston, brake fluid returns to master cylinder
reservoir tank. Watch the level of the surface of reservoir tank.
4. Remove wire then swing cylinder body down over brake pad assemblies.
5. Install lower sliding pin bolt and tighten to specification. Refer to BR-21, "
Components" .
6. Check brake for drag.
7. Inspect fluid level, then install master cylinder reservoir cap.
8. Install wheel and tire. Refer to WT-6, "
Rotation" .
Removal and Installation of Brake Caliper and Disc RotorEFS0062V
REMOVAL
1. Remove wheel and tire using power tool.
2. Drain brake fluid, as necessary. Refer to BR-10, "
Drain and Refill" .
NOTE:
Do not remove union bolt unless removing cylinder body from vehicle.
3. Remove union bolt as necessary and torque member bolts, then remove cylinder body and torque mem-
ber assembly.
NOTE:
Position cylinder body aside using suitable wire, as necessary.
NOTE:
When servicing cylinder body, remove sliding pin bolts and cylinder body from torque member.
4. Remove torque member, as necessary.
5. Remove disc rotor.
