Rear Cast Iron Brake Disc 370*22mm Center Bell For Audi A6 C7 Back

Generally, the front wheels are replaced with brake calipers, discs and skins, and the rear wheels only occupy 20% of the brakes. It is not necessary to replace the calipers (or some cars are electronic parking). Of course, changing the brakes generally involves replacing the enlarged wheel hub. In order to be more beautiful, replace the enlarged disc in the back!

1, When the rear brake disc increases, the caliper will extend outward, and the center distance between the caliper and the wheel will increase. Although the contact surface of the caliper is the same without changing, the force arm increases, which is the lever principle, and the braking effect will be better.

2, The stronger the rear brake, the better. If it is too strong, it is easy to shake the tail. If it is too weak, the brake is easy to nod. My front brake is ap5200, and the effect is pretty good. Sometimes it's easy to nod when in an emergency. I think the rear brake should be strengthened properly. It's not easy to nod when in an emergency. It should also increase the stability of the car body.

3, The larger the brake disc, the greater the thermal redundancy, the easier it is to dissipate heat, and the temperature of the brake pad is relatively difficult to rise

If the brake disc is slightly worn and does not need to be replaced, it can be repaired according to the original thickness, wear width and depth of the brake disc. However, most of the worn brake discs encountered in practice have been replaced for two reasons. First of all, many brake discs are seriously worn and have no maintenance value. The friction between iron and iron will make a noise. If you don't care about this noise and drive for a few days, the brake disc will be completely damaged. Even if there is a noise, drive to the 4S store for inspection immediately. If it is far from the 4S store, the brake disc will be worn out after arriving. If the wear is serious, it must be replaced directly

How often is the brake disc replaced?

Replacement cycle of brake disc: generally, the brake pad needs to be replaced after 30000-40000 km, and the brake disc needs to be replaced after 70000 km. The service time of the brake pad is relatively short. Generally, the brake disc of the car is replaced after twice, and the rear brake needs to be replaced after 80000-100000 km.

How to deal with the rusty brake disc?

1. Treatment of slight rust: generally, the common problem of brake disc is rust. If it is only slight rust, it can be removed by continuous braking during driving. Because the disc brake is braked by the friction between the brake caliper and the brake pad, the rust can be removed by multiple braking. Of course, the premise is to be in a safe road section.

2. Treatment of serious rust: the above method is still useful for slight rust, but it can't be solved if the rust is serious. Because the rust is too stubborn, the brake pedal and steering wheel will shake obviously during braking, which can not be "polished", but also accelerate the wear of brake pads. Therefore, in this case, it is best to find professional maintenance personnel to remove the brake disc for grinding and clean the rust. If the rust is particularly serious, even a professional repair shop can't do anything. It's time to change a brake disc.
