Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety if working on the brake system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake rotor for warping by placing a dial indicator on the rotor surface.
  - If warped beyond manufacturer specifications (usually more than 0.002 inches), replace.
3. Remove the caliper by unscrewing the caliper bolts with a socket.
4. Slide the caliper off the rotor and hang it securely (do not let it dangle by the brake line).
5. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
6. Install new rotors, ensuring they are properly seated.
7. Reinstall the caliper and torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove old brake pads from the caliper bracket.
2. Clean the caliper bracket and inspect for any debris or damage.
3. Install new brake pads, ensuring proper orientation and fit.
4. Apply brake grease to the back of the pads to reduce noise and ensure smooth operation.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect tie rods, ball joints, and control arms for wear or damage.
2. Replace any worn components using appropriate tools (e.g., ball joint separator).
3. Torque new components to the manufacturer's specifications.

5. Wheel Alignment and Tire Balance

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a complete wheel alignment check.
3. Have tires balanced if uneven wear is observed.
