Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and wear safety gloves and goggles.

2. Remove Wheels

Sub-steps:
1. Loosen the lug nuts on the front wheels using a lug wrench.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Inspect brake rotors for warping (more than 0.002 inches is typically unacceptable).
2. If warped, remove the brake caliper by loosening the caliper bolts (use a socket set).
3. Suspend the caliper using a bungee cord to prevent strain on the brake line.
4. Remove the brake rotor by unscrewing the retaining screws or any clips.
5. Install new rotors, ensuring they are properly seated and aligned.
6. Reattach the brake caliper and torque bolts to manufacturer specifications (typically around 30 Nm).

4. Replace Brake Pads

Sub-steps:
1. Remove old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake tool or C-clamp to create space for new pads.
3. Install new brake pads, ensuring they are oriented correctly.
4. Reinstall the caliper over the new pads.

5. Reassemble and Test

Sub-steps:
1. Reattach the wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and remove the jack.
3. Torque the lug nuts to the manufacturer's specifications (typically 100 Nm).
4. Test the brakes by pressing the pedal a few times to ensure proper engagement.
