Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake rotor for warping or excessive wear; replace if necessary.
3. If replacing, remove the caliper bolts and lift the caliper off the rotor. Use a brake caliper tool to compress the caliper piston if needed.
4. Remove the old rotor by unscrewing any retaining screws.
5. Install the new rotor, making sure it is properly seated and secure.
6. Reattach the brake caliper and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; replace if they are below the recommended thickness (usually 3mm).
2. Remove the brake pads from the caliper bracket.
3. Install new brake pads and ensure they are correctly positioned.
4. Apply brake grease to the back of the pads to reduce noise.

4. Wheel Alignment

Sub-steps:
1. After reassembling the brakes and wheels, take the vehicle to a professional alignment shop.
2. Ensure that both camber and toe settings are adjusted to manufacturer specifications.
