Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors: Check for warping using a dial indicator; if warped, replace.
Replace Brake Pads:
1. Remove the caliper bolts with a socket wrench.
2. Slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly aligned.
Install New Rotors: If needed, remove the old rotor by unscrewing any retaining screws and sliding it off the hub. Install the new rotor and tighten screws to the manufacturer's specification.

4. Reassemble and Test

Reattach the caliper over the new brake pads and secure it with the bolts; torque to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
Reconnect the battery.
