Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues while working on the braking system.

2. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Remove the wheel using a socket set.
- Visually inspect rotors for warping or scoring.
- If warped, replace rotors with new ones.
Replace Brake Pads:
- Remove the caliper by unbolting it and sliding it off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket and reattach the caliper.

3. Wheel Alignment and Balancing

Alignment Check:
- Use alignment equipment to check for any misalignments.
- Adjust as necessary to ensure proper alignment.
Balancing:
- Use a tire balancer to check wheel balance.
- Add weights to balance tires if necessary.

4. Reassembly

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
Ensure all tools are removed from the work area.
