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 avoid electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect and Measure Brake Rotors

Remove the brake caliper using a socket set; support it with a bungee cord to avoid strain on the brake line.
Remove the brake pads from the caliper bracket.
Measure the rotor thickness using a micrometer, and check for warping with a runout gauge.
- If warped beyond manufacturer specifications (usually 0.002 inches), proceed to rotor replacement.

4. Replace or Resurface Rotors (if necessary)

If rotors are warped, replace them with new ones or have them resurfaced if within specifications.
Install new rotors if replacing. Torque the rotor retaining screws to the manufacturer’s specifications.

5. Install New Brake Pads

Apply brake grease to the backing of new pads to minimize noise.
Install the new brake pads into the caliper bracket.

6. Reassemble Brake Components

Reattach the brake caliper and torque the bolts to the manufacturer's specifications.
Reinstall the wheel and lug nuts, torquing them in a crisscross pattern.

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads against the rotor.
Lower the vehicle from jack stands.
