Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working on the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper by loosening the caliper bolts.
3. Take out the old brake pads; inspect for uneven wear.
4. Install new brake pads, ensuring they are oriented correctly.
5. Reattach the caliper and torque the bolts to manufacturer specifications.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Remove the rotor by taking off any retaining screws and sliding it off the hub.
2. Measure rotor thickness; if below specifications or warped, replace with new rotors.
3. If resurfacing, use a brake lathe following manufacturer's specifications.
4. Clean the rotor surface with brake cleaner before reinstallation.
5. Reinstall the rotor and secure it with the retaining screws.

4. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Perform a four-wheel alignment using appropriate alignment equipment.
