Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery for safety.

2. Brake Rotor Inspection and Replacement

Sub-step 1: Remove the wheel by loosening lug nuts and lifting the vehicle on jack stands.
Sub-step 2: Remove the brake caliper by unbolting it and hanging it aside (do not let it dangle from the brake line).
Sub-step 3: Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
Sub-step 4: Measure the rotor thickness and runout. If warped beyond specifications, replace it with new rotors.
Sub-step 5: Install new rotors and ensure they are secure.

3. Brake Pad Inspection and Replacement

Sub-step 1: Inspect brake pads for wear; if they are below the minimum thickness, replace them.
Sub-step 2: Apply brake grease to the backing of the new pads to reduce noise.
Sub-step 3: Install new brake pads into the caliper brackets.

4. Wheel Alignment and Balancing

Sub-step 1: Take the vehicle to a professional alignment shop to check and adjust wheel alignment.
Sub-step 2: Balance the tires if necessary to ensure even contact with the road.

5. Suspension Check

Sub-step 1: Inspect suspension components for any signs of wear, such as torn bushings or damaged control arms.
Sub-step 2: Replace any worn parts as needed.
