Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Rotors

Inspection: Check rotors for signs of warping or scoring.
Replacement: If warped, use a socket set to remove the caliper and bracket.
- Carefully slide the caliper off the rotor.
- Remove the rotor from the hub by unscrewing any retaining screws.
- Install new rotors, ensuring they are properly seated.

4. Inspect and Replace Brake Pads

Remove the caliper bracket if necessary.
Check brake pads for thickness; replace if below the manufacturer’s specifications.
Install new brake pads, applying brake grease to the backing as needed.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Pump the brake pedal a few times to ensure proper brake engagement.
