Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, safety goggles, gloves
Lift the vehicle using the jack and secure it with jack stands. Remove the wheel where the noise is occurring.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts with a socket wrench.
2. Carefully lift the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the pads for wear; if they are less than 3mm thick, replace them.
5. Apply brake lubricant to the back of the new pads to reduce squeaking.
6. Install the new brake pads into the caliper bracket.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Check the rotor surface for uneven wear or scoring. If worn, consider resurfacing or replacing the rotors.
2. If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install the new rotor (or resurfaced rotor) and torque the screws to the manufacturer's specifications.

4. Reassemble Braking Components

Sub-steps:
1. Reattach the brake caliper over the new pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s torque specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle and Test

Sub-steps:
1. Lower the vehicle and remove jack stands.
2. Torque the lug nuts to the manufacturer’s specifications in a star pattern.
3. Pump the brake pedal several times to ensure proper pad and rotor seating before test driving.
