Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Jack the vehicle up and securely place it on jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Inspect the brake rotor for warping or scoring.
2. If warped, remove the caliper by loosening the caliper bolts and support it with a bungee cord.
3. Remove the rotor by unscrewing the retaining screws if applicable.
4. Install new rotors, ensuring they are clean and free of grease.
5. Torque the rotor screws to manufacturer specifications.

4. Replace Brake Pads

Tools Required: Brake pad spreader, torque wrench.
Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake pad spreader.
3. Install new brake pads into the caliper bracket.
4. Reattach the caliper over the new pads and torque the caliper bolts.

5. Reassemble and Test

Tools Required: Torque wrench, lug wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications.
3. Test brake operation by pressing the brake pedal several times before driving.
