Removal and Installation

WARNING:

Clean dust on the brake caliper and the brake pads using a vacuum dust collector to minimize the hazards of airborne particles or other material.

 

CAUTION:

• Do not depress the brake pedal.

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.

• Do not bend, twist, or pull the brake hoses and piping.

• Do not reuse drained brake fluid.

 

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

 

REMOVAL

CAUTION:

• Before removing the rear brake caliper, perform the "REMOVAL/REPLACEMENT OF REAR BRAKE PAD OR REAR BRAKE CALIPER". Refer to Description.

• If necessary, release the parking brake and move the piston into the brake caliper body. Perform the "INSTRUCTIONS FOR RELEASING PARKING BRAKE WHERE PARKING BRAKE SWITCH CANNOT BE USED". Refer to Description.

 

Observe the brake fluid level in the reservoir tank. Partially drain brake fluid if necessary. Refer to Draining.

Remove the rear wheel and tire using a power tool. Refer to Removal and Installation.

Secure the disc brake rotor using wheel nuts.

Disconnect the harness connector from the rear brake caliper.

Remove the union bolt, the copper sealing washers, and separate the brake hose from the brake caliper. Discard the copper sealing washers. Refer to Exploded View.

CAUTION:

Do not reuse copper sealing washers.

 

Remove the slide pin bolts. Refer to Exploded View.

CAUTION:

Do not drop the brake pads or the brake caliper.

 

Remove the brake caliper from the torque member.

Remove the slide pins from the torque member.

Remove the brake pads, shims, shim cover, wear indicators, and pad retainers from the torque member. Refer to Exploded View.

CAUTION:

• Do not damage the pad retainers or the piston boot.

• Do not drop the brake pads, shims, shim cover, or wear indicators.

• Note the position of components during removal to aid with installation.

 

Remove the bolts and the torque member.

INSTALLATION

Install the torque member and the bolts. Tighten the bolts to the specified torque. Refer to Exploded View.

Apply rubber grease to the slide pins.

Install the slide pins to the torque member.

Install the brake pads, shims, shim cover, wear indicators, and pad retainers to the torque member. Refer to Exploded View.

CAUTION:

Do not drop the brake pads, shims, or pad retainers.

 

Install the brake caliper to the torque member.

Install the slide pin bolts. Tighten the slide pin bolts to the specified torque.

Assemble the union bolt (A) and the copper sealing washers (1) to the brake hose and install it as an assembly to the brake caliper. Align the brake hose L-pin by aligning it with the brake caliper hole, and tighten the union bolt to the specified torque. Refer to Exploded View.

CAUTION:

Do not reuse copper sealing washers.

 

Connect the harness connector to the rear brake caliper.

Refill with new brake fluid and bleed air from the brake system. Refer to Bleeding Brake System.

CAUTION:

• Do not reuse drained brake fluid.

• Do not spill or splash brake fluid on the disc brake rotor.

 

Depress the brake pedal several times and verify that drag does not exist.

Install the rear wheel and tire. Refer to Removal and Installation.

CAUTION:

• When installing the rear brake caliper, perform the "REMOVAL/REPLACEMENT OF REAR BRAKE PAD OR REAR BRAKE CALIPER". Refer to Description.

• Perform the "ADJUSTMENT OF BRAKE CALIPER INITIAL POSITION". Refer to Description.

 

INSPECTION AFTER INSTALLATION

Check the drag of the rear disc brake. If any drag is found, perform the following procedure:Remove the rear brake pads. Refer to Removal and Installation.

CAUTION:

Before removing the rear brake pads, perform the "REMOVAL/REPLACEMENT OF REAR BRAKE PAD OR REAR BRAKE CALIPER". Refer to Description.

 

Install the brake pads.

CAUTION:

• When installing the rear brake caliper, perform the "REMOVAL/REPLACEMENT OF REAR BRAKE PAD OR REAR BRAKE CALIPER". Refer to Description.

• Perform the "ADJUSTMENT OF BRAKE CALIPER INITIAL POSITION". Refer to Description.

 

Depress the brake pedal several times. Check the drag of the rear disc brake again. If any drag is found, disassemble the brake caliper body. Refer to Disassembly and Assembly.

 

Burnish contact surfaces after replacing the brake caliper or if a soft pedal occurs at very low mileage. Refer to Periodic Maintenance Operation.

Disassembly and Assembly

WARNING:

Clean dust on the brake caliper using a vacuum dust collector to minimize the hazards of airborne particles or other material.

 

CAUTION:

• Do not reuse drained brake fluid.

• Do not damage the piston boot.

 

DISASSEMBLY

Remove the brake caliper from the vehicle. Refer to Removal and Installation.

Remove the slide pin boots from the torque member. Refer to Exploded View.

Remove the bushing from the slide pin.

Remove the bleeder valve and cap.

Perform the inspection after disassembly.

INSPECTION AFTER DISASSEMBLY

Brake Caliper Body

Check the brake caliper body for rust, wear, cracks, and damage. Replace the brake caliper if any abnormal condition is detected.

CAUTION:

Clean the brake caliper using new brake fluid. Do not use mineral oils such as gasoline or kerosene.

 

Torque Member

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

Slide Pins and Bolts

Check the slide pins and bolts for rust, wear, cracks, and damage. Replace the parts if any abnormal condition is detected.

ASSEMBLY

Install the bleeder valve and cap. Refer to Exploded View.

Apply rubber grease to the matching surfaces (A) of the slide pin (1) and the bushing (2).

 

Install the bushing to the slide pin.

Apply rubber grease to the matching surfaces (A) of the slide pins (1) and the slide pin boots (2).

 

Install the slide pins and slide pin boots to the torque member (3).
