355*22mm Cast Iron Brake Disc For Audi RS6 C7 Rear Oversized Disc

Serious wear of cast iron brake disc will occur:

1. Brake fatigue

2. Brake jitter and abnormal noise

3. Damage the brake disc, resulting in premature and excessive wear of the brake disc.

4. Serious damage to the braking system may occur.

You must repair the car in these cases

1. Abnormal brake noise
When driving, if you step on the brake, it will make a sharp and harsh metal friction sound, which is mostly caused by the hard material impurities in the brake pads, resulting in the hard wear of the brake pads and brake discs. If it is drum braking, it may be due to improper adjustment of the measuring vehicle clearance or delayed return of the brake shoes. If there is abnormal noise when releasing the hand brake after a long time of parking, it is mostly the problem of the return of the measuring pad or brake shoe

2. Brake softens
If you feel very soft when stepping on the brake and help a lot, this situation is mostly due to the failure of the caliper, such as the pedal travel becomes longer due to excessive damage of the brake pad and brake disc, or there is too much water in the vehicle oil, air in the brake oil circuit, etc. If this is the case, you can step on the brake for several times to see if the pedal is still soft. If so, you should check and repair it in time

3. Brake does not return
This situation is more like when the brake becomes soft, there is no resistance when stepping down, and there is no strong rebound. At this time, we should be vigilant. First look at the amount of brake oil left in the brake oil tank, and then immediately drive to the repair shop for straight inspection, because this situation is likely to be the leakage or air in the brake oil circuit

4. The brakes harden
This problem is relatively simple, and the hardening of the test vehicle will not affect the braking effect. When the car comes to a steady stop, step on the brakes to make the test car hard, and then start the car. If the brakes become soft after landing, it means that the agent car has no problem, otherwise you have to go to the repair shop for inspection

5. Tremble when stepping on the test vehicle
This kind of situation is not common. It is basically because the brake pads or brake discs are damaged too much and the disc surface is not flat. Therefore, when stepping on the car, due to constant friction, you will find that the brake pedal bounces and feels shaking. In this case, you should go to the repair shop for inspection in time. If it is a problem with the disc, it is generally replaced directly

6. Car deviation
When stepping on the brake system, the steering wheel will deflect to one side, which is mainly caused by the uneven force of the wheel cylinder on the left and right sides of the test vehicle on the test pad. This situation will also lead to the eccentric wear of the brake pad. Therefore, when this problem is found, it is best to check it immediately. If you just change the brake pad, it will not cure the symptoms
