Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect the brake pads for thickness; if less than 3mm, replace them.
If replacing, remove the caliper bolts using a socket set and slide the caliper off.
Remove the old brake pads and install new pads, ensuring they are properly seated.
Reinstall the caliper and torque bolts to the manufacturer's specifications (typically 20-25 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove the caliper bracket using the appropriate socket.
Remove the rotor by pulling it straight off the hub.
Install new rotors, ensuring they are clean and free of debris.
Reattach the caliper bracket and torque bolts to the specified torque.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 75-80 ft-lbs).
Pump the brake pedal to ensure proper seating of the brake pads.
