Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Existing Pads:
- Remove the caliper by loosening the mounting bolts with a socket wrench.
- Slide the caliper off and support it without stretching the brake line.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to prevent squeaking.
- Install the new pads into the caliper bracket.
- Reattach the caliper and tighten the mounting bolts to the manufacturer’s torque specification (typically around 20-25 lb-ft).

5. Inspect and Replace Brake Rotors (if necessary)

Remove Old Rotors:
- If rotors are damaged, remove them by loosening any retaining screws or caliper brackets as needed.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Install the new rotors, ensuring they are seated properly.

6. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specification (typically around 100-150 lb-ft).

7. Test the Brake System

Pump the brake pedal several times to seat the pads against the rotors.
Perform a test drive to ensure brakes are functioning correctly.
