Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands, safety goggles, and gloves.
Parts Required: New brake pads, new rotors (if needed), brake caliper grease.

2. Lift the Vehicle

Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Use the jack to lift the front or rear of the vehicle, depending on which brakes are grinding, and secure with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brakes.

4. Remove Brake Caliper

Loosen and remove the caliper mounting bolts using a socket.
Carefully slide the caliper off the rotor and support it using a hanger wire or bungee cord to avoid stressing the brake line.

5. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the old pads with new ones to ensure correct size.
Apply brake caliper grease to the back of the new brake pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

6. Inspect and Replace Brake Rotor (if necessary)

If the rotors are scored or excessively worn, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor securely and torque bolts to the manufacturer’s specifications.

7. Reinstall Caliper and Wheel

Slide the caliper back over the new brake pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.

8. Lower the Vehicle

Carefully lower the vehicle back to the ground and torque the lug nuts in a crisscross pattern to the specified torque.
