Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely elevate the front using a jack and jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Check for Warping: Use a dial gauge to measure rotor thickness at multiple points.
Remove Wheel: Use a socket set to remove lug nuts and take off the wheel.
Remove Brake Caliper: Unbolt the caliper using a socket and suspend it with a bungee cord (do not let it hang by the brake line).
Remove Brake Rotor: Unscrew any retaining screws and slide the rotor off the hub.
Install New Rotor: Place the new rotor onto the hub and secure it with screws.

3. Inspect and Replace Brake Pads

Remove Old Pads: Slide the old brake pads out of the caliper bracket.
Install New Pads: Insert new brake pads into the caliper bracket, ensuring they are seated correctly.
Reinstall Caliper: Position the caliper back over the pads and bolt it securely.

4. Inspect and Replace Suspension Components (if necessary)

Check Control Arms and Bushings: Look for cracks, tears, or excessive play.
Replace Components: If damaged, unbolt and remove the component and install the new part, torquing bolts to the manufacturer’s specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Reconnect the battery.
