Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using the jack and support it securely 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, brake cleaner, C-clamp or brake caliper tool.
Sub-steps:
1. Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
2. Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and the rotor with brake cleaner.
5. Install new brake pads, ensuring they are seated properly in the bracket.
6. Reattach the caliper over the new pads and secure it with the caliper bolts.

4. Replace or Resurface Rotors (if necessary)

Tools Required: Rotor holding tool (if required for your model).
Sub-steps:
1. Check the rotor for surface damage; if warped or excessively worn, replace or resurface as needed.
2. Install new rotors or replace existing ones according to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications.
3. Reconnect the battery.
4. Pump the brake pedal a few times to seat the pads before driving.
