my Toyota Camry Eighth Generation (2018-present) has a grinding noise when braking what's wrong

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety glasses and gloves.

2. Remove Wheel

1. Loosen the lug nuts on the wheel where the grinding noise originates.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

1. Examine the brake pads for thickness; replace if worn down to the indicator.
2. Check the brake rotors for any grooves, scoring, or warping.
   • If the rotor surface is damaged, it may need resurfacing or replacement.
3. Inspect the brake calipers for proper movement and any signs of leakage.
4. Ensure that the brake hardware (clips, shims) is intact and correctly positioned.

4. Replace Brake Pads and Rotors (if necessary)

1. If replacing pads, remove the caliper bolts and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. If replacing rotors, remove any retaining screws and slide the rotor off the hub.
4. Install new rotors (if applicable), ensuring they are secured with the retaining screws.
5. Install new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specification (typically 25-35 ft-lbs).

5. Reassemble and Test

1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specification (typically 76-80 ft-lbs).
3. Pump the brake pedal several times to seat the new pads.
4. Test drive the vehicle at low speeds to verify the repair.
