Solution

1. Preparation

Gather tools and materials needed for the repair.
Safety equipment: gloves and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly with a socket wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check the rotors for warping or grooves. If warped, proceed to replace.
Remove the caliper bolts with a socket wrench and slide the caliper off the rotor.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.

B. Replace Brake Rotors (if necessary)

Install new rotors, ensuring they are clean and free of oil.
Reinstall any retaining screws (if applicable) and torque to manufacturer specifications.

C. Inspect and Replace Brake Pads

Check the brake pads for wear. If they are less than 3mm thick, replace them.
Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads and install them into the caliper bracket.

4. Reassemble

Reattach the caliper over the new rotor and pads.
Torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

5. Test Brakes

Pump the brake pedal to seat the pads against the rotors.
Perform a test drive to ensure that the issue is resolved.
