New composite brake disc

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.

How to surface treatments for Brake Rotor



Zinc-Plating:  Zinc plating is a chemical process that is applied onto most rotors to prevent rotors from rusting.  This chemical plating process is usually available in black zinc, gold zinc, or silver zinc.  Although the entire rotors is zinc plated, the zinc will only remain on areas that do not come into contact with the brake pads.

Each Performance Brake Rotor is immersed in different solution tanks in the coating process. The final result is a thick protective coating that will help prevent rusting and give you a great custom look.

When you receive your Rotors they will be completely Black or Silver. As soon as you install them and start braking, the friction from the pads will wipe the zinc from the pad surface turning it Silver leaving the holes, slots and the rest of the brake Rotor Zinc coated in the color you selected. (See before and after photos below) The Zinc coating that is removed from the Pad surface quickly dissipates and will not gum up the pad surface or affect the braking performance in any way. Emoji
