Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts on the wheel before raising the vehicle.
2. Raise the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the brake caliper bolts and slide the caliper off the rotor.
2. Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for wear; replace if the friction material is less than 3mm thick.
5. Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor tool (if applicable), socket set.
Sub-steps:
1. Inspect the brake rotors for any signs of scoring or warping.
2. If rotors are damaged, remove the old rotors by unscrewing the retaining screws (if present).
3. Clean the hub surface to ensure proper seating of the new rotor.
4. Install new rotors, ensuring they are properly aligned.

5. Reassemble Braking System

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the brake caliper over the new pads and rotor.
2. Torque the caliper bolts to the manufacturer’s specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to the manufacturer's specification.
