Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, impact wrench (if needed).
Remove the wheel to access the brake assembly.
Inspect rotors for signs of warping or scoring.
If warped, remove the caliper by loosening caliper bolts and suspend it with a wire hanger.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors, ensuring they are properly seated.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Check for uneven wear; replace if necessary.
Apply brake grease to the backing of the new pads to reduce noise.
Install new pads into the caliper bracket.

5. Reassemble and Torque Components

Reattach the caliper over the new pads and secure with caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 90-100 ft-lbs).

6. Test Drive and Check

After repairs, take the vehicle for a test drive to assess brake performance.
Listen for any abnormal sounds and check for vibrations during braking.
