Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner (if warning light is present).
Safety Warnings: Ensure the vehicle is on a flat surface and secured with jack stands. Disconnect the battery before working on electrical components.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts with a socket wrench and carefully lift the caliper off the rotor.
- Inspect the brake pads for uneven wear. If wear is significant or pads are below manufacturer specifications, replace them.
Replacement:
- Use brake cleaner to clean the caliper and rotor surfaces.
- Remove the old brake pads and install new ones, ensuring they are oriented correctly.
- Reinstall the caliper and torque the caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).

4. Check and Service Calipers

If calipers are sticking, remove them and inspect the piston for corrosion or damage.
Clean the caliper slide pins and apply brake grease before reinstallation.
If damaged, replace the caliper with a new or remanufactured unit.

5. Inspect Rotors

If rotors are warped or below minimum thickness, replace them.
For minor unevenness, consider having them resurfaced by a professional.

6. Verify Brake System Functionality

Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to ensure proper seating of the pads.
Check brake fluid level and top up as necessary.
