Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen lug nuts slightly while the wheel is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake cleaner, micrometer
Inspect the brake rotors for thickness and runout; replace if they are below specification or show excessive runout.
Clean the brake rotor surface with brake cleaner.
Install new brake rotors, ensuring they are properly aligned.
Torque the rotor retaining bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Tools Required: C-clamp, brake grease
Remove the caliper by unscrewing the caliper bolts.
Use a C-clamp to compress the caliper piston for easier removal.
Inspect the brake pads for wear; replace if they are worn unevenly or are below specification.
Apply brake grease to the backing of new pads and install them.
Reinstall the caliper and torque the caliper bolts to specifications.

5. Reinstall Wheel and Perform Final Checks

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to specifications.
Reconnect the battery.
