Solution

1. Preparation

Gather tools and parts required.
Safely elevate the vehicle using a jack and secure it on jack stands.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a lug wrench to loosen and remove the wheel nuts.
- Take off the wheel to access the brake components.
Inspect Brake Pads
- Check the thickness of the brake pads. Replace if below the manufacturer’s specifications (usually less than 3mm).
- Remove the caliper bolts using a socket set, then slide off the caliper.
- Remove the old brake pads and install new ones.
Check and Replace Brake Rotors
- Inspect the brake rotors for warping using a dial indicator or visual inspection.
- If warped, remove the rotor by unscrewing the retaining screws and pull it off the hub.
- Install a new rotor, ensuring proper alignment with torque specifications (usually 80-100 ft-lbs).

3. Suspension Inspection and Repair

Inspect Suspension Components
- Check control arms, bushings, and struts for wear or damage.
- Tighten any loose bolts and replace any worn components.
Alignment Check
- After replacing components, perform a wheel alignment to ensure proper handling and tire wear.
