Solution

1. Preparation

Gather tools and safety gear.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly before lifting the vehicle.
2. Use the jack to lift the vehicle and support it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors (if warped)

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the brake caliper by unbolting it and hanging it securely (do not let it dangle).
2. Take off the brake pads from the caliper bracket.
3. Unbolt and remove the rotor from the hub.
4. Install new rotors, ensuring they are properly seated.
5. Torque the rotor bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Pads (if worn)

Tools Required: Brake pad spreader, torque wrench
Sub-steps:
1. Check the thickness of the brake pads; replace if below the minimum thickness.
2. Apply brake grease to the backing of new pads to prevent squeaking.
3. Reinstall the brake pads into the caliper bracket.
4. Reinstall the caliper over the new pads and torque the caliper bolts.

5. Reassemble and Test

Tools Required: Lug wrench, torque wrench
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications in a crisscross pattern.
4. Test the brakes by gently pressing the pedal before driving.
