Solution

1. Preparation

Gather the necessary tools: jack, jack stands, lug wrench, brake pad spreader tool, and a clean rag.
Ensure the vehicle is on a flat surface and turn off the ignition.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels.
Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels.

3. Inspect the Calipers

Examine each caliper visually for leaks or damage.
Check the mounting bolts for tightness and ensure they are not stripped.
Inspect the brake pads for uneven wear and measure pad thickness.

4. Test Caliper Function

Use the brake pad spreader tool to compress the caliper piston.
Release the tool and observe if the piston retracts back smoothly without sticking.
If the caliper is stuck or does not retract, it may need to be replaced.

5. Check Brake Fluid

Inspect the brake fluid reservoir for the correct level and clarity.
If the fluid is contaminated, perform a brake fluid flush and replace with fresh fluid.

6. Reassemble

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s specified torque.
