BRAKE CALIPER ASSEMBLY (1 PISTON TYPE) : Disassembly and Assembly

DISASSEMBLY

1.  Remove the brake caliper from the vehicle. Refer to BR-35, "BRAKE CALIPER ASSEMBLY (1 PISTON TYPE) : Removal and Installation".
2. Remove sliding pins and sliding pin boots from torque member.
3. Place a wooden block in brake caliper body and blow air from union bolt hole to remove piston and piston boots.

   WARNING: Do not get fingers caught between piston and brake caliper body.

   CAUTION: Do not reuse piston boots.

4. Remove piston seals from brake caliper body using suitable tool.

CAUTION:

•  Do not damage cylinder inner wall.
•  Do not reuse piston seals.

5.  Remove bleeder valve and cap.

INSPECTION AFTER DISASSEMBLY

Brake Caliper Body

Check the inner wall of the brake caliper body for rust, wear, cracks or damage. Replace the brake caliper body if any abnormal condition is detected.

CAUTION: Always clean with new brake fluid. Do not clean with mineral oil such as gasoline and light oil.

Torque Member

Check the torque member for rust, wear, cracks or damage. Replace the torque member if any abnormal condition is detected.

Piston Check the surface of the piston for rust, wear, cracks or damage. Replace the piston if any abnormal condition is detected.

CAUTION: Piston sliding surface is plated. Do not polish with sandpaper.

Sliding Pin and Sliding Pin Boot

Check the sliding pins and sliding pin boots for rust, wear, cracks or damage. Replace the parts if any abnormal condition is detected.

ASSEMBLY

1.  Install bleeder valve and cap.
2.  Apply rubber grease to each piston seal (1), and install them to the brake caliper body.

CAUTION: Do not reuse piston seal.

3. Apply rubber grease to the piston boots. Cover each piston end with a piston boot, and then install cylinder side lip on piston boot securely into a groove on brake caliper body.

   CAUTION: Do not reuse piston boots.

4. Apply brake fluid to each piston (1). Push each piston into cylinder body by hand and push piston boot (2) piston-side lip into the piston groove.

   CAUTION: Press the piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.

5. Apply rubber grease to bushing; install bushing to sliding pin.
6.  Apply rubber grease to sliding pins and sliding pin boots, install sliding pins and sliding pin boots to torque member.
7.  Install the brake caliper to the vehicle. Refer to BR-35, "BRAKE CALIPER ASSEMBLY (1 PISTON TYPE) : Removal and Installation".

INSPECTION AFTER INSTALLATION

1.  Check the drag of front disc brake. If any drag is found, follow the procedure described below.
2.  Remove brake pads.
3.  Using a suitable tool, press the piston into the brake caliper body.

   CAUTION: Do not damage the piston boots.

4.  Install brake pads.
5.  Depress the brake pedal several times.
6.  Check the drag of front disc brake again. If any drag is found, disassemble the brake caliper body.
7.  Burnish contact surfaces after refinishing or replacing disc rotors or if a soft pedal occurs at very low mileage.

   Refer to BR-18, "Brake Burnishing".
