Repair Procedure
NOTE
Prior to beginning work, ensure that all previous brake related Service Bulletins for the vehicle
have been applied.
1. Raise and secure the vehicle.
Place vehicle on a lift and raise using recommended lift points.
2. Remove the front wheels by removing the lug nuts.
3. Remove the brake caliper assembly.
A. Remove the sliding pins/bolts and remove the caliper from the caliper mounting bracket.
8. Carefully hang brake calipers so no strain is placed on the brake hoses.
C. Remove brake pads from mounting bracket.
D. Remove the caliper mounting bracket bolts and remove the caliper mounting bracket.
E. Save wear indicators (if applicable).
• Replace if damaged or worn.
• Discard used brake pads.
• Discard used anti-squeal shims.
4. Clean and re-grease caliper sliding pins.
A. Replace worn or damaged parts as necessary.
8. Using brake cleaner, flush caliper of all old sliding pin grease. Clean the sliding pins of
old grease.
C. Re-grease the sliding pins with Toyota lithium soap-based glycol grease (P/N 08887-01206).
5. Inspect the front discs.
A. Remove the rotors.
• If rotor is difficult to remove, use the threaded holes to assist removal. Place bolts in
the holes and tighten to assist removal.
• If corrosion is present, use a rust penetrant to remove corrosion.
8. Using a micrometer, check rotor thickness. If rotor is below the minimum allowable thickness,
replace the rotor. (Refer to the applicable Repair Manual for further information.)
C. Ensure rotor mounting surface (backside of rotor hat) and hub are free of debris or corrosion .
If necessary, clean with a wire brush.

Repair Procedure (Continued)
D. Re-install brake rotors.
(1) Using a dial indicator, measure the lateral run-out. (Refer to the applicable Repair
Manual for further information.)
• If the run-out is more than the maximum, change the installation position of the
disc to minimize run-out.
• If the run-out is more than the maximum even when the installation position is
changed, turn or machine the rotor.
(2) If the rotor needs to be turned or machined, use an on-car brake rotor lathe
(preferred) or remove and turn on a brake lathe. (Refer to brake lathe specific
instructions for details.)
NOTE
Before turning or machining rotor, make sure inside rotor mounting surface and
brake lathe hub are free from debris or corrosion.
(3) Install rotor (if rotor was replaced or removed for turning).
NOTE
• Make sure rotor mounting surface and hub are free of debris or corrosion.
• Clean rotor friction surfaces with brake cleaner if needed.
(4) Install rotor onto hub.
(5) Use lug nuts to retain rotor to hub while installing caliper.
E. Inspect and reinstall the caliper mounting bracket.
(1) Inspect the mounting bracket for any damage, rust, corrosion, or debris. If damaged,
replace the mounting bracket. Remove any rust, corrosion, or debris using a wire
brush or similar tool.
(2) Install the mounting bracket and mounting bracket bolts.
(3) Using a torque wrench, tighten the caliper mounting bolts.

• Do NOT apply grease to the entire area
of the backing plate.
Apply 1 - 2 mm thickness of supplied TCMC
shim grease to the areas of the brake pad
backing plate as indicated.
B. Install the anti-squeal shims on the brake pad
backing plate.

or wear, and that all rust and dirt are removed.
• Do NOT apply grease or lubricants to pad support plates when reinstalling.
