How to choose the right brake caliper when modifying the brakes of your car? Ludi Auto Technology - BMW modification, Mercedes-Benz modification, Audi modification parts manufacturer and share with you:
Generally speaking, we modify the brakes to change the calipers of the opposite piston type. The calipers are: four-piston, six-piston, eight-piston.
It is easy to tell how many pistons a caliper is. The round mouths on both sides of the caliper are the pistons. Count them, and there are several pistons that are several pistons. This can be known at a glance, just give Xiaobai some popular science.
Of course, there are some common mistakes;
1. First of all, to correct a wrong statement, it is not that the more pistons the caliper, the stronger the brake. Whether the braking effect of a car is good or not depends on too many things, such as oil circuit design, brake master cylinder, pedal design, brake oil selection, brake disc, brake pad and so on.
For example, some American big bikes have single-piston floating calipers, but the pressure of the calipers can crack the discs of ordinary family cars.
So the question is, what is the difference between multi-piston calipers and single-piston calipers? The answer is that the multi-piston caliper has more friction area, the caliper is smaller, and the brake feedback is more delicate.
2. Of course, some car owners will ask, after changing the multi-piston caliper, will the master cylinder of the original car not be able to carry it? This question depends on the fuel supply data of your car's master cylinder. Generally, the car on the market, such as the master cylinder of the BMW F3/8x code, can be driven completely. (It is a few models that cannot be driven. When you change the brakes, the technician will tell you)
3. Also, some car owners bought a complete set of imported original car brake calipers, thinking that there will be no jitter problem after they are installed on the car. To explain here, it does not mean that the full set of imported brake calipers will not shake. Because every car is made of tolerances, and over time, the car itself will wear out. These small errors will affect the performance of the caliper. This problem is written in the manual of the brake caliper kit.
Common old brake brands are: Brembo, AP, alcon, endless. These are the four kings of brake brands. These four brands are also regulars in DTM, Le Mans and other events. As for the new generation of brake brands, there are also many, but the quality still has to pass the test of time, so I will not recommend it here.
As for the question of how many piston calipers should be selected, I can only give a rough reference here. After all, the problem of this relationship is a bit complicated. If necessary, you can consult the technical personnel of Guangzhou Saiqu.
