Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery for safety.

2. Inspect and Remove Brake Components

Remove the wheel using a socket set.
Inspect the brake rotor for warping; if warped, proceed to replace.
Remove the caliper bolts and carefully lift the caliper away from the rotor.
Take out the brake pads for inspection.

3. Replace or Resurface Rotors

If the rotor is warped beyond specification, replace it with a new rotor.
If minor, resurface the rotor as per manufacturer specifications.
Torque the rotor bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

4. Replace Brake Pads

Install new brake pads, ensuring proper alignment with the caliper.
Apply brake grease to the back of the pads to reduce noise.
Reinstall the caliper over the new pads and torque the bolts to specification (usually around 25-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to specification (usually around 80 ft-lbs).
Reconnect the battery.
Lower the vehicle and test the brakes at low speeds to ensure proper operation.
