How to recover the rust?

Auto brake is generally made by cast iron, so the car stops or stock for a period of time will gradually rust, this is normal, not a brake disc quality. If a smaller range of rust on the brake disc, you can not deal specifically with the small amount of rust on the brake disc when the vehicle is in motion brake is removed. If the rust is more serious, the vehicle will brake vibration or jitter, such as the vibration of the brake pads, steering wheel vibration or jitter, body vibration. Serious corrosion Brake removal is difficult to pass, even if rust is removed because of the uneven thickness of the brake discs may cause the brake vibration. Therefore every two months against  disc brake once maintained, in order to avoid corrosion of the brake disc too serious.
How to recover the rust of brake disc?
First, find a safe level sections, we must ensure the safety! Then normal driving a vehicle on the road, and the normal use of the brakes. By reference to the following example repeated braking times. (Note: For hybrid vehicles or electric vehicles vehicles, the shift lever in the N position when braking.)
1, according to the deceleration of 0.3G braking from 60 MPH to 0 mph (96km / h to 0 km / h), repeated five times (during braking, the vehicle about 10 seconds with about 120 meters.)
2, in accordance with 0.3G deceleration braking (braking, the vehicle about 6 seconds with about 55 meters from 40 mph to 0 mph (64km / h to 0 km / h), repeated 10 times.)
3, in accordance with 0.3G deceleration braking (braking, the vehicle about 5 seconds with about 30 meters from 30 MPH to 0 mph (48km / h to 0 km / h), repeated 20 times.)
4, in accordance with 0.3G deceleration braking from 60 MPH to 40 mph (96km / h to 64km / h), repeated 10 times (during braking, the vehicle about 3 seconds with about 70 meters.)
Deceleration of 0.3G braking from 40 mph to 20 mph (64km / h to 32km / h), repeated 15 times (during braking, the vehicle traveling about 40 meters in about 3 seconds.)
The brake vibration of how to deal with
Vehicle maintenance brake disc persists brake vibration, the vehicle shall be open to the repair shop overhaul. The repair shop should first find out the cause vibration of the brake disc and in accordance with reasonable maintenance. If the cause of the vibration of the brake disc thickness is uneven, to be grinding brakes. If the grinding not solve the problem, you may need to replace the brake discs and brake pads.
