Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn on the hazard lights.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3 mm, they should be replaced.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Resurface/Replace Brake Rotors

Inspect Rotors:
- Check for any visible damage or warping.
Resurface/Replace Rotors:
- If the rotor is scored or warped, remove the caliper bracket bolts and take off the rotor.
- If resurfacing, take the rotors to a machine shop. If replacing, install new rotors by sliding them onto the hub and securing them with the retaining screws.

5. Reassemble Braking Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and lower the vehicle.

6. Test Brake Functionality

Pump the brake pedal several times to seat the new pads.
Ensure that the brake warning light is off and that the brakes feel firm.
