about car brake system

First, a good brake has low heat failure. There are two ways to solve the brake failure caused by high temperature of the brake. One is to solve it from the material and the other is to solve the problem of heat dissipation. The perforated disk that I replaced is from the heat dissipation. In order to optimize, the replacement of high-temperature brake pads is optimized from the material, and when necessary, additional brake vent pipes are added to force the brake calipers and discs to cool down.
Second, a good brake has good braking linearity. The brake linearity is closely related to the structure of the caliper. Most of the models on the market are of single-piston structure. The single-sided piston pushes the brake pads while pulling the brake pads on the other side. The opposing piston pushes the brake pads inward at the same time, so that the force of the brake pads is more uniform. Therefore, some riders will replace the original single-piston calipers with opposing two-pistons, four-pistons, etc., for the better The brake is linear.
Third, good brakes have good wear resistance, and durability is also crucial to the brakes. So how to modify the durability of the brake discs? The easiest way is to reduce the pressure between the brake pads and the brake disc. Assuming that the braking force we need when braking is certain, after changing to a larger diameter brake disc, the pressure exerted by the brake pads will be reduced, and the brake system It won't be so expensive. The circumference of a large-diameter brake disc is also long, and the use of the disc is larger, and the brake durability will be improved!

Precautions

There are several points to pay attention to for the modification of the brake system of street cars. The first point is the number of pistons in the brake calipers. The opposed small six-piston calipers may not be better than the four-piston calipers. The pistons need brake fluid to drive. Our car is original The oil supply of the brake master cylinder of the factory is fixed. The more pistons, the greater the amount of oil required, and the more the pistons of the brake master cylinder push more. The terrible thing is that your brakes are not fully powered by the caliper. Hundred, such brake modification will only bring disaster, so don't blindly pursue multi-piston calipers when modifying brakes. The second point is the problem of front and rear braking force distribution. Some people say that the senior caliper set is changed in the front of our car, and the original brake at the rear will cause excessive braking force in the front and lock up. In fact, it is the opposite. Let’s make an analogy. Assuming that the front and rear pistons require a 2-to-1 fuel supply when braking at full force. Now, with the big four-piston calipers, the fuel supply will become 4-to-2, which means that the front-wheel braking force reaches Half of the time, the rear wheel has reached 100% braking force. Of course, this data is inaccurate, but in the actual process, the temperature of the rear wheel brake disc of a vehicle that only changed the front wheel brake will be much higher than before. The non-smoke rear brake is now beginning to smoke, and this is the reason. Therefore, the front and rear braking force adjustment devices are available on the car. Therefore, the editor's suggestion is to change the brakes before and after the matching plan, such as the first four and the second, the first six and the fourth, the first four and the small four and so on.
