Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Components

Brake Rotor Inspection:
- Remove the wheel using a socket set.
- Inspect the brake rotor with a dial indicator for warping (should be within manufacturer specifications).
- If warped, proceed to replace the rotors.
Brake Pad Inspection:
- Remove caliper bolts and slide the caliper off the rotor.
- Check the brake pads for thickness and even wear. Replace if worn unevenly or below minimum thickness.
Replacement Steps:
- For rotors:
  1. Remove the old rotor and clean the hub surface.
  2. Install the new rotor and torque to manufacturer specifications (typically around 75-85 lb-ft).
- For pads:
  1. Compress the caliper piston using a brake tool.
  2. Install new pads and reattach the caliper, torquing bolts to manufacturer specifications (typically around 30-35 lb-ft).

3. Inspect Suspension Components

Check tie rods, control arms, and bushings for any signs of wear or damage.
Replace any worn components as needed, ensuring proper alignment afterward.

4. Wheel Alignment and Balancing

After replacing brake components, have the wheels aligned and balanced to ensure proper vehicle handling.
