Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Inspect for uneven wear. If worn, remove the caliper bolts with a socket set.
- Slide the caliper off and remove the old brake pads.
- Install new brake pads, ensuring they are properly seated.
Brake Rotors:
- Check rotors for warping using a dial gauge. If warped beyond manufacturer specs, replace them.
- Remove the caliper bracket and rotor. Clean the hub surface with a wire brush.
- Install new rotors, ensuring they are fastened to the hub securely.

4. Inspect Suspension Components

Visually inspect tie rods, control arms, and bushings for any signs of damage or excessive wear.
Replace any worn components using appropriate tools (e.g., socket set, wrenches).

5. Reassemble and Test

Reinstall the caliper bracket and wheel.
Tighten the lug nuts to the manufacturer’s specified torque settings.
Lower the vehicle and reconnect the battery.
