WARNING:

Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne

particles or other materials.

CAUTION:

• While removing caliper body, do not 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 caliper body. In this case, hang caliper body with a wire so as not to stretch the brake

hose.

• Do not damage the piston boot.

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

• Always replace shim and shim cover as a set when replacing brake pads.

• Keep rotors free from grease and brake fluid.

• 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-39, "Brake Burnishing"

.

CALIPER INSPECTION

Cylinder Body

• Check inside surface of cylinder for score, rust wear, damage or foreign materials. If any of the above condi-

tions 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 new brake fluid for cleaning. Do not use mineral oils such as gasoline or kerosene. 

Torque Member

Check the torque member for wear, cracks, and damage. If damage or deformation is present, replace the

torque member.

Piston

Check the piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the above

conditions are observed. 

CAUTION:

Piston sliding surface is plated, do not polish with emery paper even if rust or foreign materials are

stuck to sliding surface.

Sliding Pin Bolts and Sliding Pin Boots

Check the sliding pins and sliding pin boots for wear, damage, and cracks. If damage or deformation is

present, replace the affected part.

3. Apply rubber grease to the new piston boot (1). Cover the piston

end (2) with the piston boot (1), and then install the cylinder side

lip on the piston boot (1) securely into the groove on the cylinder

body.

CAUTION:

• Do not reuse piston boot.

• Press pistons in evenly and vary the pressing points to

prevent the cylinder inner wall from being damaged.

4. Install the piston (1) into the cylinder body and insert the piston

boot (2) side lip into the piston groove as shown. 

CAUTION:

Press pistons in evenly and vary the pressing points to pre-

vent the cylinder inner wall from being damaged.

5. Apply rubber grease to the sliding pin boots, then install sliding pins and sliding pin boots on the torque

member.

6. Install the caliper body on the torque member. Refer to
