Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Safety glasses and gloves should be worn during the procedure.

2. Remove Wheel

Use a lug wrench to loosen lug nuts, then raise the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Inspect the brake pads for wear; if they are worn below the manufacturer’s specification (typically around 3mm), replace them.
To install new brake pads, apply brake grease to the back of the pads and slot them into place.

4. Inspect and Resurface or Replace Rotors

Check the rotor for scoring or warping. If the rotor is damaged, it should be resurfaced or replaced.
If resurfacing, use a brake lathe following manufacturer specifications. If replacing, remove the rotor retaining screws and pull the rotor off the hub.
Install the new rotor, ensuring it is properly seated and secure.

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer’s torque specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts to the specified torque (typically 75-80 ft-lbs).
Reconnect the battery and check brake fluid level, topping off if necessary.
