Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel Assembly

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts of the front wheels slightly while the vehicle is on the ground.
2. Raise the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Inspect the brake rotors for warping using a dial indicator.
2. If warping is found, remove the caliper by unscrewing the caliper bolts and support it without stressing the brake line.
3. Remove the rotor by unscrewing the retaining screws (if applicable).
4. Install new rotors (if warped) and ensure they are torqued to manufacturer specifications.
5. Inspect brake pads; if worn unevenly, replace them with new pads, ensuring they are properly seated.
6. Reinstall the caliper and torque bolts to specifications.

4. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Tighten the lug nuts to the manufacturer’s torque specification in a crisscross pattern.
4. Test the brake system by pressing the brake pedal multiple times before driving.
