Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Engage the parking brake and use wheel chocks for safety.

2. Remove the Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Inspect the brake rotors visually for signs of warping or uneven wear.
2. If warped, use a rotor puller to remove the rotors.
3. Clean the hub surface where the rotor mounts.
4. Install new rotors, ensuring they are properly seated.
5. Torque the rotor bolts to the manufacturer’s specifications (usually around 90 Nm).

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide off the caliper and support it (do not hang it by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are oriented correctly.
5. Reinstall the caliper and torque the caliper bolts to manufacturer specifications.

5. Reinstall the Wheel

Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts to secure the wheel.
3. Lower the vehicle and remove the jack stands.
4. Torque the lug nuts in a star pattern to the manufacturer’s specifications (usually around 120 Nm).
