Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and support it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it and hanging it securely without straining the brake line.
Remove old brake pads and inspect the caliper hardware.
Install new brake pads, ensuring they are properly seated.
Reattach the caliper and torque bolts to manufacturer specifications (typically 20-25 ft-lbs).

4. Inspect and Replace Brake Rotors (if warped)

Remove the brake rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
If warped or below minimum thickness (usually around 0.1 inches), replace the rotor with a new one.
Install the new rotor and secure it in place.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 100-150 ft-lbs depending on wheel type).

6. Test Drive

Perform a test drive to check for proper brake function and any vibrations during braking.
