Solution

1. Preparation

Tools Required: Wheel chocks, jack and jack stands, lug wrench, torque wrench, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts on the wheel using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely to access the braking components.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake pads and hang it using a bungee cord or similar device to avoid strain on the brake line.
Inspect the brake pads for wear; replace if the friction material is less than 3mm thick.
If replacing pads, remove the old pads and clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they are properly seated in the caliper bracket.
Reattach the brake caliper over the new pads.

4. Inspect and Resurface/Replace Rotors

Check the brake rotor for scoring or warping.
If the rotor is damaged, remove it by unscrewing the rotor retaining screws (if fitted).
Resurface the rotor if it's within specifications or replace it if necessary.
Install the rotor back onto the hub, ensuring it is aligned properly.

5. Reassemble and Torque

Reinstall the brake caliper and torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the specified value (usually 76-83 ft-lbs).
