Brake Disc A0004230512 B For Mercedes W205C205 4-MATIC

When the automobile brake disc fails, it should be checked according to the following steps:

1. Visual inspection: First, park the vehicle on a flat ground and use a jack to lift the vehicle so that the tires are off the ground. Then, check whether there are cracks, uneven wear and deformation on the surface of the brake disc to ensure that the surface of the brake disc is smooth and free from obvious damage.

2. Touch inspection: Touch the surface of the brake disc gently with your hands to check whether there are obvious pits, wear or corrosion. The surface of the brake disc should be smooth and level, without obvious bad marks.

3. Thickness measurement: Use a brake disc thickness gauge or caliper to measure the thickness of the brake disc. According to the regulations of the vehicle manufacturer, what range should the minimum thickness of the brake disc be, so as to ensure that the thickness of the brake disc is within a safe range.

4. Check the cooling grooves and cooling holes: Check whether the cooling grooves and cooling holes on the surface of the brake disc are blocked or damaged, so as to ensure good cooling effect of the brake disc and avoid overheating of the brake disc.

5. Check the installation: Check the installation of the brake disc to ensure that the connection between the brake disc and the wheel hub is tight, and there is no looseness or foreign interference.

6. Test the braking effect: in a safe environment, drive at a low speed and lightly step on the brake pedal to feel the braking effect of the brake disc and check whether there is abnormal braking feeling or abnormal sound.

Through the above inspection steps, the failure of the brake disc can be found in time to ensure the normal work of the brake disc and improve the safety and reliability of the vehicle. If there is a problem with the brake disc, it should be repaired or replaced in time to ensure the normal operation of the brake system of the vehicle.
