Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper by unbolting it (typically requires a socket set).
- Slide the caliper off the rotor and suspend it using a bungee cord.
- Remove the brake pads and measure their thickness.
Replace Brake Pads:
- If uneven wear is found, replace the affected brake pads with high-quality parts.
- Ensure that the new pads are compatible with the existing rotor.
Check Calipers:
- Inspect calipers for any signs of sticking or damage.
- If calipers are faulty, replace them with new or refurbished units.

4. Inspect and Resurface Rotors

Check Rotor Surface:
- Measure rotor thickness with a micrometer.
- If rotors are within specifications, resurface them to ensure a flat surface.
Replace Rotors:
- If rotors are below the minimum thickness or damaged, replace them.
- Install new rotors according to manufacturer specifications.

5. Reassemble Brake System

Reinstall the brake pads and caliper.
Torque caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reattach the wheel and lower the vehicle.

6. Final Checks

Reconnect the battery and check brake fluid level, topping off as necessary.
Test the brake system without driving to ensure proper engagement.
