Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if required for safety.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check brake pads for thickness (should be at least 3mm) and any uneven wear.
Replace:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor without disconnecting the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they are properly aligned.
- Use brake cleaner to clean any dust from the caliper and rotor.

4. Inspect and Resurface or Replace Rotors

Inspect: Check the rotor surface for grooves, cracks, or excessive wear.
Resurface or Replace:
- If resurfacing, use a brake lathe to smooth out the rotor surface.
- If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor ensuring it sits flush against the hub.

5. Reassemble and Torque

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
