Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before beginning work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and support it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Take out the old brake pads from the caliper bracket.
Inspect the caliper for any damage or stuck pistons; clean with brake cleaner if necessary.
Install new brake pads into the caliper bracket. Ensure they are seated properly and aligned.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or below the minimum thickness specification, remove them by unscrewing the rotor retaining screws (if equipped) and sliding the rotor off the hub.
Install new rotors, ensuring they are clean and free of debris.
Torque the rotor retaining screws to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the brake caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal several times to seat the new brake pads against the rotors.
