Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is safely parked on a level surface and engaged in gear or park.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial gauge to measure rotor runout. If warping is detected (greater than 0.002 inches), proceed with replacement.
Remove Tires: Use a lug wrench to remove the wheel lug nuts and take off the wheels.
Remove Brake Caliper: Use a socket set to unbolt the caliper from its bracket. Hang it securely using a wire to avoid stress on the brake line.
Remove Rotor: Unbolt and remove the rotor. If rusted, use a rubber mallet to gently tap it off.
Install New Rotor: Place the new rotor onto the hub, ensuring it sits flush. Bolt it in place according to manufacturer specifications (typically around 10-15 ft-lbs).
Reinstall Caliper: Position the caliper back over the rotor and fasten the bolts to the specified torque (usually around 30-40 ft-lbs).

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are below the manufacturer’s recommended minimum (typically around 3 mm), replace them.
Remove Old Pads: Slide the old brake pads out of the caliper bracket.
Install New Pads: Position new pads into the caliper bracket, ensuring proper alignment with the rotor.

4. Check and Adjust Wheel Alignment

Alignment Check: After reassembling the brakes, take the vehicle to a professional alignment shop to ensure proper alignment.
Adjust if Necessary: Follow the technician's guidance to correct any misalignment.
