Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary safety equipment (gloves, goggles).

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen lug nuts slightly without removing them.
2. Lift the vehicle using the jack and secure 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. Remove the caliper by loosening the caliper bolts and lifting it off the rotor.
2. Secure the caliper with a bungee strap to avoid tension on the brake line.
3. Remove the brake pads from the caliper bracket.
4. Check the rotor for thickness and warping; replace if necessary.
5. Install new rotors, ensuring they are clean and properly seated.
6. Reinstall the caliper and brake pads, tightening bolts to manufacturer's torque specifications.

4. Check and Replace Brake Pads

Tools Required: Brake pad spreader (optional), torque wrench.
Sub-steps:
1. Inspect the brake pads for uneven wear; replace if worn below the minimum thickness.
2. Apply anti-squeal grease to the back of the new pads.
3. Install the new brake pads into the caliper bracket.
4. Reassemble the caliper over the new pads and secure it.

5. Reinstall Wheel and Lower Vehicle

Tools Required: Lug wrench, torque wrench.
Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts onto the wheel studs.
3. Lower the vehicle and remove the jack stands.
4. Torque the lug nuts to the manufacturer's specifications.
