Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket and inspect for uneven wear.
If any pads are worn unevenly, replace them with high-quality pads that match OEM specifications.

4. Inspect and Replace Brake Rotors

Check the rotors for any signs of scoring, warping, or uneven surface.
If necessary, remove the rotors by unscrewing the retaining screws and pulling them off the hub.
Install new rotors or have the existing ones resurfaced to ensure a flat and even surface.

5. Caliper Inspection and Reinstallation

Clean the caliper slide pins and apply brake grease to ensure smooth movement.
Reinstall the caliper over the new brake pads and rotor, tightening the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).

6. Final Checks and Reassembly

Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Lower the vehicle and pump the brake pedal to seat the brake pads.
