If you press the brake hard but cannot lock the tires, it means that the braking force generated by the pedal is insufficient, which is very dangerous. If the braking force of a car is too low, although it will still lock up during sudden stepping, it will also lose its tracking control ability. The limit of braking occurs at the moment before the brake locks, and the driver must be able to maintain control of the brake pedal at this force. To increase the brake pedal force, you can start by increasing the brake power assist device and replacing it with a larger Air Tank. However, the increase is limited because excessive vacuum assist force can cause the brakes to lose their gradual progression, and the brakes will be stuck to the bottom with just one step. As a result, the driver cannot effectively and stably control the brakes. The most ideal approach is to modify the master cylinder and slave cylinder, and further utilize Pascal's principle to increase the brake pedal force. When modifying the cylinder and fixture, the size of the disc can be increased simultaneously. The braking force is the force distance exerted by the friction force generated by the brake pads on the wheel axle. Therefore, the larger the diameter of the disc, the greater the braking force generated.

Excessive temperature is the main cause of brake pad degradation, so cooling the brakes becomes particularly important. For disc brakes, cooling air should be blown directly towards the fixture. The main reason for the deterioration of brakes is due to the boiling of brake oil inside the fixture. If cooling air can be introduced into the fixture during driving through appropriate pipes or specially designed wheels. In addition, if the wheel itself has good heat dissipation effect, it can also share some of the heat from the disc and fixture. Drawing lines, drilling holes, or ventilated discs can maintain a stable braking effect and avoid the sliding effect caused by high-temperature iron filings between brake pads and discs, effectively ensuring braking force.
