Toyota Brake Pad Clicking Noise Technical Service Bulletin

Quick guide from the manual

This technical service bulletin addresses a clicking noise that may occur in 1990-2000 Toyota vehicles when changing travel direction (e.g., from Drive to Reverse). The noise is caused by normal brake pad-to-caliper clearances. The solution involves applying a specific disc brake caliper grease to the pad support plates or caliper to minimize this movement.

Required materials

Use Disc Brake Caliper Grease (50 g tube), Part Number: 08887-80609.

Floating type brake caliper procedure

1. Lift up or remove the brake caliper and suspend it securely. Do not disconnect the flexible hose.
2. If equipped with an anti-squeal spring, remove it.
3. Remove the brake pads with anti-squeal shims.
4. Remove the pad support plates from the torque plate. Clean dust from the pad support plates, torque plates, and brake pads.
5. Apply a 1-2 mm thick layer of disc brake caliper grease to both sides of the pad support plates.
6. If the pad support plate is fixed with adhesive tape, follow the specific flow chart provided in the manual to determine if you need to remove the tape or apply grease to the contact portion.
7. Apply a 1-2 mm thick layer of grease to the caliper as indicated in the illustration.
8. Reinstall the brake pads with anti-squeal shims and the anti-squeal spring (if equipped).
9. Press the piston in firmly and install the brake caliper.
10. Install the wheel assembly.

Fixed type brake caliper procedure

Identify your brake pad type:

• Type A: Has a projection on the upper and lower side of the brake pad.
• Type B: Has a flat upper and lower edge on the brake pad backing plate.

For Type A:

1. Remove the anti-squeal spring, clip, and pad guide pin.
2. Remove the brake pads with anti-squeal shims.
3. Clean dust from the brake pads.
4. Apply a 1-2 mm thick layer of disc brake caliper grease to the areas indicated in the illustration.
5. Reinstall the brake pads with anti-squeal shims, then install the pad guide pin, clip, and anti-squeal spring.
6. Install the wheel assembly.

For Type B:

1. Remove the clip, pins, and anti-rattle spring/pad retainer clip.
2. Remove the brake pads with anti-squeal shims.
3. Clean dust from the brake pads.
4. Apply a 1-2 mm thick layer of disc brake caliper grease to the areas indicated in the illustration.
5. Reinstall the brake pads with anti-squeal shims, then install the pad guide pin, clip, and anti-squeal spring.
6. Install the wheel assembly.

Important warnings

• Do NOT apply grease to the friction surfaces of the brake pads or the disc rotor.
• Clean any excess grease from the brake pad and caliper after application.
• Under normal usage conditions, this grease is effective for 6 months to 1 year.
