Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the wheel using a socket set.
3. Inspect the brake rotors for warping using a runout gauge; if warped, proceed with replacement.
4. Remove caliper bolts using a torque wrench and lift the caliper off the rotor.
5. Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.
6. Install the new rotor, ensuring it is seated properly.
7. Reattach the caliper and torque bolts to the manufacturer's specifications (typically around 79 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
1. If brake pads are worn unevenly, remove them from the caliper bracket.
2. Clean the caliper bracket and inspect for corrosion or damage.
3. Install new brake pads, ensuring they are oriented correctly.
4. Apply brake grease to the backing of the pads to reduce noise.

4. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop for proper alignment.
2. Have the wheels balanced to ensure smooth operation while driving.
