Solution

1. Preparation

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

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the issue is suspected.
Secure the vehicle with jack stands.

3. Remove Wheels

Using a lug wrench, remove the lug nuts and take off the wheels to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check rotors for warping using a dial indicator.
- If warped beyond specifications (usually more than 0.002 inches), replace them.
Replace Rotors:
- Remove caliper bolts and slide off the caliper.
- Remove the old rotor and install the new rotor.
- Reinstall the caliper and torque the bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

5. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; replace pads if less than 3mm.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new pads, ensuring they are correctly positioned.
- Apply brake grease to the backing of the pads (if recommended) to reduce noise.

6. Reassemble and Lower Vehicle

Reinstall wheels and torque lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
Lower the vehicle off the jack stands.

7. Test Brakes

Before driving, pump the brake pedal to ensure pads are seated correctly and firm pressure is achieved.
