Solution

1. Preparation

Gather required tools and parts.
Ensure vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is heard.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor.
- Inspect brake pads for wear; replace if they are below the minimum thickness (generally 3mm).
Brake Rotors:
- Check for scoring or warping by feeling the surface with your hand.
- If damaged, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Calipers:
- Inspect for sticking pistons or damage.
- If necessary, rebuild or replace the caliper.

5. Replace Components (if needed)

Install new brake pads, ensuring they are seated properly in the caliper bracket.
If rotors are damaged, install new rotors following the manufacturer’s specifications for torque (typically 90-100 ft-lbs for rotor bolts).
Reassemble the caliper and tighten bolts to the specified torque (usually around 25-30 ft-lbs).

6. Reinstall Wheel and Test

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (often around 100-110 ft-lbs).
Start the vehicle and gently apply the brakes to ensure proper function and to seat the new pads.
