Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, anti-squeal grease
Safely park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for additional safety.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it to avoid stress on the brake line.
Remove old brake pads from the caliper bracket.
Inspect the pads; if worn below the manufacturer's specifications, replace them.
Apply anti-squeal grease to the back of the new pads and install them in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for wear; if they are scored or warped, replace them.
If replacing, remove the caliper bracket and the rotor by unscrewing the retaining screws (if present).
Clean the new rotor with brake cleaner to remove any protective coating.
Install the new rotor and reattach the caliper bracket.

5. Reassemble and Torque

Reattach the caliper onto the rotor and tighten the caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to the specified torque.

6. Test Brakes

Pump the brake pedal a few times before driving to ensure proper brake pad seating.
Conduct a test drive to listen for any remaining noises and ensure brakes function correctly.
