Solution

1. Preparation

Gather tools and ensure a safe working environment.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel and Brake Components

Loosen lug nuts on the affected wheel slightly while the car is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel.
Remove the brake caliper by unscrewing the caliper mounting bolts.
Suspend the caliper using a bungee cord to avoid stress on the brake line.
Remove the brake pads from the caliper bracket.

3. Inspect and Replace Rotors

Use a dial indicator to measure the rotor runout; if it exceeds manufacturer specifications, replace the rotor.
If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install the new rotor, ensuring it is seated properly.
Torque the retaining screws to the manufacturer's specification.

4. Install New Brake Pads

Apply brake grease to the backing of the new brake pads to prevent squeaking.
Insert the new brake pads into the caliper bracket.
Reattach the caliper over the new pads and torque the caliper mounting bolts to specification.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification.
Reconnect the negative battery terminal.
