BRAKE CALIPER ASSEMBLY : Removal and Installation

INFOID:0000000009365025

WARNING:

Clean any dust from the brake caliper and brake pads with a vacuum dust collector. Do not blow with

compressed air.

CAUTION:

• While removing caliper, do not depress the brake pedal because the piston will pop out.

• Do not damage piston boot.

• Do not allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe

off immediately and wash with water if brake fluid spills on painted surfaces.

• Keep disc brake rotor free from brake fluid.

• Do not reuse drained brake fluid.

NOTE:

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

ing.

REMOVAL

1. Remove the front wheel and tire using power tool.
2. Remove union bolt and disconnect brake hose from brake caliper. Discard the copper sealing washers.
3. Remove bolts and torque member including brake caliper.
4. Remove disc brake rotor. If reusing the disc brake rotor, apply matching marks on the wheel hub and disc

brake rotor to aid installation.

CAUTION:

Put matching marks on the wheel hub and disc brake rotor, if it is necessary to remove disc brake

rotor.

INSTALLATION

1. Install disc brake rotor, align the matching marks if installing the original disc brake rotor.

CAUTION:

• Replace the disc brake rotor if it has been dropped or sustained an impact.

• Align the marks on disc brake rotor and wheel hub at the time of installation when reusing disc

brake rotor.

2. Install the torque member including brake caliper to the steering knuckle and tighten the torque member

bolts to the specified torque. Refer to

BR-35, "BRAKE CALIPER ASSEMBLY : Exploded View"

CAUTION:

• Replace the torque member if it has been dropped or sustained an impact.

washers (1). Tighten union bolt (A) to the specified torque. Refer

BR-21, "FRONT : Exploded View"

CAUTION:

• Do not reuse copper sealing washers.

4. Refill reservoir tank with new brake fluid and bleed air from the brake hydraulic system. Refer to

DISASSEMBLY

WARNING:

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

borne particles or other materials.

CAUTION:

• While removing brake caliper, do not depress brake pedal because piston will pop out.

• Do not damage the piston boot.

NOTE:

• The front brake caliper (LH) is shown. The front brake caliper (RH) is similar.

• Do not remove the pad return springs, brake pads, and pad retainers from the torque member when disas-

sembling and assembling the brake caliper.

block.

5. Remove piston seal from cylinder body using suitable tool.

CAUTION:

Be careful not to damage cylinder inner wall.

6. Remove bleeder valve and cap.
7. Perform inspection after disassembly.

INSPECTION AFTER DISASSEMBLY

Brake Caliper

Check the inner wall of brake caliper for corrosion, wear, and damage. Replace as necessary.

CAUTION:

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

Torque Member

Check torque member for wear, cracks, and damage. Replace as necessary.

Piston

Check the piston surface for corrosion, wear, and damage. Replace as necessary.

CAUTION:

The piston sliding surface is plated. Do not polish with sandpaper.

Sliding Pins, Sliding Pin Bolts, Sliding Pin Boot

Check the sliding pins, sliding pin bolts, and sliding pin boots for wear, damage, and cracks. Replace as nec-

essary.

ASSEMBLY

1. Install bleeder valve and cap.
2. Apply clean brake fluid to new piston seal (1), and install to

groove in cylinder body.

CAUTION:

Do not reuse piston seal.

3. Apply Syntheso® GLK 1 grease or equivalent to piston boot (1).

Cover the piston (2) end with new piston boot, and then install

cylinder side lip on piston boot securely into a groove on cylinder

body.

CAUTION:

Do not reuse piston boot.

4. Push piston (1) 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 pre-

vent cylinder inner wall from being rubbed.

5. Apply rubber grease to the mating surfaces (A) of the sliding pin

(1) and the bushing (2).

6. Install the bushing to the sliding pin.

7. Apply rubber grease to the mating surfaces of the sliding pins

(1) and the sliding pin boots (2).

8. Install the sliding pins and sliding pin boots to the torque mem-

ber (3).

9. Install the cylinder body to the torque member with the sliding pin bolts. Refer to
