WARNING:

Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air
borne particles or other materials.

CAUTION:

While removing cylinder body, never depress the brake pedal because the piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of the caliper assembly. In this case, suspend cylinder body with wire so as not to
stretch brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Burnish the brake contact surface after refinishing or replacing rotors, after replacing pads, or if a
soft pedal occurs at very low mileage. Refer to 

BR-32, "BRAKE BURNISHING PROCEDURE"

 .

CAUTION:

By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.

When attaching the pad retainer, attach it firmly so that it
does not float up higher than the torque member, as
shown in the figure.

3.

Install lower sliding pin bolt, and tighten it to the specified torque.

4.

CALIPER INSPECTION
Cylinder Body

CAUTION:

Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

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.

Torque Member

Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.

Piston

CAUTION:

Piston sliding surface is plated, do not polish with emery paper even if rust of 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.

Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace
applicable part.

Sliding Pin, and Sliding Pin Boot

Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the applicable part.

Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.

3.

To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.

4.

Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.
