Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, micrometer, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to prevent any electrical hazards.

2. Replace Brake Pads and Rotors (if necessary)

Remove Wheel:
1. Loosen lug nuts with a lug wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Inspect and Remove Brake Caliper:
1. Remove bolts securing the brake caliper using a socket set.
2. Carefully lift the caliper off the rotor and support it with a bungee cord or rope (do not let it hang by the brake line).
Replace Rotor:
1. Remove the rotor by unscrewing any retaining screws, if present.
2. Clean the hub surface with a wire brush to ensure proper seating for the new rotor.
3. Install the new rotor, securing it with screws if applicable.
Install New Brake Pads:
1. Compress the caliper piston using a caliper tool to create space for the new brake pads.
2. Position the new brake pads into the caliper bracket.
3. Reinstall the brake caliper over the new pads and secure it with bolts.
Reattach Wheel:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts, then lower the vehicle.
3. Torque the lug nuts to the manufacturer’s specifications (typically around 100 lb-ft).

3. Inspect and Adjust Suspension Components

Check for Wear:
1. Inspect suspension components such as tie rods, control arms, and bushings for any signs of wear or damage.
Realign Wheels:
1. If any components were replaced, take the vehicle to a professional alignment shop for proper alignment.
