Solution

1. Preparation

Gather required tools and parts.
Ensure vehicle is parked on a flat surface and the parking brake is engaged.
Use jack stands for safety when lifting the vehicle.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Loosen lug nuts with a socket wrench and remove the wheel.
- Tools Required: Socket set, jack stands.
Remove Brake Caliper:
- Unbolt the caliper from the bracket using the appropriate socket.
- Support the caliper with a bungee cord to avoid straining the brake line.
- Tools Required: Socket set.
Remove Brake Pads:
- Slide the brake pads out of the caliper bracket.
- Inspect for uneven wear or damage.
Remove Brake Rotor:
- If necessary, remove the retaining screws and slide the rotor off the hub.
- Inspect the rotor for warping; replace if necessary.
Install New Rotor:
- Position the new rotor onto the hub and secure with retaining screws.
- Ensure it is seated properly.
Reinstall Brake Pads and Caliper:
- Insert new or inspected brake pads into the caliper bracket.
- Reattach the brake caliper and tighten bolts to the specified torque (typically 20-30 ft-lbs).

3. Check and Replace Suspension Components (if needed)

Inspect Suspension Components:
- Check control arms, bushings, and struts for wear or damage.
Replace Worn Components:
- If any suspension parts are worn, remove and replace them with new parts.
- Follow manufacturer specifications for torque values during reinstallation.
