Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety: Wear appropriate personal protective equipment (PPE) such as gloves and safety glasses.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel by loosening the lug nuts and using a jack to lift the vehicle.
2. Secure the vehicle with jack stands.
3. Remove the brake caliper bolts and slide off the caliper.
4. Take out the old brake pads by removing the retaining clips.
5. Inspect the brake pads; if worn below the manufacturer’s specifications, replace with new pads.
6. Apply brake grease to the back of the new pads to prevent squealing.
7. Reinstall the caliper and secure the bolts to the manufacturer’s torque specifications.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the rotor by taking off any retaining screws or caliper brackets.
2. Inspect the rotor surface for grooves or excessive wear.
3. If the rotor is scored or warped, either resurface it or replace it with a new rotor.
4. Clean the rotor surface with brake cleaner before installation.
5. Reinstall the rotor and secure it properly.

4. Final Assembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
3. Pump the brake pedal a few times to ensure proper caliper operation.
