Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the braking system.

3. Inspect and Replace Brake Pads

Inspect the Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Check the thickness of the brake pads; if they are below 1/4 inch, replace them.
Replace the Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads and ensure they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect the Rotors:
- Check for grooves or uneven wear on the rotors.
- If they are severely worn or scored, they should be replaced.
Replace the Rotors:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are aligned properly.

5. Reassemble the Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque settings.
Reinstall the wheels and lower the vehicle.

6. Final Checks

Pump the brake pedal to ensure proper engagement of the pads against the rotor.
Check brake fluid levels and top off if necessary.
