Solution

1. Preparation

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

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the front wheels.

4. Inspect and Replace Brake Rotors

Inspect: Check the rotors for warping using a dial indicator gauge.
Replace (if warped):
1. Remove caliper bolts with a socket wrench.
2. Slide the caliper off the rotor and secure it (do not let it hang by the brake line).
3. Remove the rotor by unscrewing any retaining screws (if applicable) and sliding it off the hub.
4. Install new rotors, ensuring they are properly seated, and torque retaining screws to manufacturer specifications.

5. Inspect and Replace Brake Pads

Inspect: Check pads for wear indicators.
Replace (if necessary):
1. Remove the caliper bracket bolts and take off the bracket.
2. Slide out old brake pads.
3. Compress the caliper piston using a brake caliper tool.
4. Install new brake pads and reassemble caliper bracket.

6. Reassemble and Test

Reattach the caliper and torque bolts to specified values.
Reinstall the wheels and torque lug nuts in a crisscross pattern.
Lower the vehicle and perform a test drive to ensure braking performance is restored.
