Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent any movement of the vehicle.

2. Remove Wheel Assembly

Loosen lug nuts with a socket wrench before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to measure rotor runout. If warped beyond specifications (usually more than 0.002 inches), they should be replaced.
Replace Rotors: Remove caliper bolts and gently slide the caliper off. Remove the old rotor by unbolting it from the hub.
Install New Rotors: Place new rotors onto the hub, ensuring they fit snugly. Torque bolts to manufacturer specifications (typically around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Check Pads: Assess the thickness of the brake pads. If they are below 3mm, replace them.
Replace Pads: Remove the caliper from the bracket. Replace the old pads with new ones, ensuring they align properly in the caliper.
Reassemble Caliper: Reattach the caliper, ensuring all bolts are torqued to specifications.

5. Check Suspension Components

Inspect control arms, bushings, and strut mounts for wear.
Replace any worn components as necessary, following manufacturer specifications for torque.

6. Wheel Balance and Alignment

Take the vehicle to a professional for wheel balancing and alignment to ensure proper handling and tire wear.
