Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure no electrical issues occur while working on the brakes.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
If the brake pads are worn down (less than 3mm thickness), remove them from the caliper bracket.
Install new brake pads in the caliper bracket, ensuring they are oriented correctly.
Apply brake grease to the back of the brake pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for scoring or warping. If damage is present, remove the rotor by unscrewing the retaining screws (if applicable).
Install new brake rotors, ensuring they are clean and free of contaminants.
Torque the rotor retaining screws to the manufacturer's specifications.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
