Jekit Cast Iron Brake Disc Rear 355*12mm Floating For Audi TT

Jekit Rear Oversized Brake rotor 355*12mm Floating Kit For Audi TT

Some car rear have brake drum, We can change complete set brake kit for Rear

Some car rear no brake drum, Electronic handbrake. Then we can do rear oversized brake disc to match 

your own OEM Brake Caliper

What is the braking principle of a car?
First of all, let's popularize the car's braking principle: when the driver steps on the brake pedal, the brake oil in the brake master cylinder will generate pressure, and the liquid will transfer the pressure to the piston in the caliper of each wheel through the pipeline. The piston then drives the caliper to clamp the brake pads and brake discs, so as to generate friction and slow down the vehicle.

So... Tire braking is realized by clamping the circular brake disc during driving rotation by the brake pad in the brake caliper. If the brake disc and brake pad are not replaced for a long time, it will produce great wear, resulting in poor vehicle braking effect. Therefore, it is very important to master the relevant knowledge of brake disc.

What is the brake disc?
The brake disc, in short, is a round plate, which rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When stepping on the brake, it clamps the brake disc to slow down or stop. The brake disc has good braking effect and is easier to maintain than the drum brake.

Under what circumstances should the brake disc be replaced

1. In addition to the mileage mentioned above, if the warning light of the brake disc is on, it indicates that the loss has reached the limit and needs to be replaced immediately.

2. Check whether there are deep grooves on the brake disc. When the combined thickness of deep grooves on both sides exceeds 3mm, the brake disc needs to be replaced.

3. If the replacement frequency of the brake pad is very high, you can observe the thickness of the brake pad more. If the brake disc is worn too much, it also needs to be replaced in time, because the wear of the brake pad and the brake disc generally correspond.

Daily maintenance method of brake disc

The brake disc will generate a lot of heat when braking, so don't wash the car immediately after braking. Turn off the engine to reduce the surface temperature of the brake disc and prevent the high-temperature brake disc from deforming and cracking due to thermal expansion and contraction in contact with cold water.
In addition, the best way to improve the service life of the brake disc is to maintain good driving habits and try to avoid sudden braking and sudden stop
