Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Using a socket set, loosen the lug nuts on the affected wheel.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper bolts using a socket wrench. Carefully slide the caliper off the rotor and inspect the brake pads for thickness. If they are below 3mm, replace them.
Brake Rotors: Check the rotor surface for scoring or warping. If damaged, replace the rotor.
Calipers: Inspect calipers for leaks or sticking. If they are not functioning properly, replace them.

4. Install New Brake Pads and/or Rotors

If replacements are necessary, install new brake pads according to the manufacturer's specifications. Ensure that the pads are seated correctly in the caliper.
If rotors are replaced, install new rotors and torque the bolts to the manufacturer's specifications (usually around 80-100 ft-lbs).

5. Reassemble and Test

Reattach the brake caliper and tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the negative battery terminal.
