Increase brake pedal force
If you press hard on the brake but can't make the tire lock, then the pedal is not producing enough braking force, which is very dangerous. A car with too low a brake force will still lock up when pressed sharply, but it will also lose tracking control. The limit of braking occurs at the moment before the brake locks, and the driver must be able to maintain the brake pedal at this level of force. To increase the brake pedal force, you can first increase the brake power auxiliary device and change it to a larger Air-Tank. However, the increase range is limited, because excessive vacuum auxiliary force will make the brake lose its progressive progress, and the brake will be pressed to the end. In this way, the driver cannot effectively and stably control the brake. The ideal is to modify the main pump and the sub-pump, using the further use of PASCAL's principle to improve the brake pedal force. When refitting pump and fixture, the size of the disc can be increased at the same time. The braking force is the friction generated by the brake pad and the force applied to the wheel shaft, so the larger the diameter of the disc, the greater the braking force.
Brake cooling
Excessive temperature is the main cause of brake pad decay, so brake cooling becomes especially important. For disc brakes, cooling air should be blown directly into the fixture. Because the main reason for the decline of the brake is due to the brake oil boiling in the fixture, such as through the appropriate pipeline or through a special design of the wheel when driving the cooling air into the fixture. In addition, if the heat dissipation effect of the ring itself is good, it can also share part of the heat from the plate and the fixture. And the marking, drilling or ventilated design of the ventilated disc can maintain stable braking effect and avoid the sliding effect of high temperature iron dust between the brake pad and disc, effectively ensure the braking force.
Coefficient of friction
The most important performance index of brake pads is friction coefficient. National standards stipulate that the brake friction coefficient is between 0.35 and 0.40. Qualified brake pad friction coefficient is moderate and stable, if the friction coefficient is lower than 0.35, the brake will exceed the safe braking distance or even brake failure, if the friction coefficient is higher than 0.40, the brake is easy to suddenly lock, rollover accident.
Inspection personnel of the National non-metallic Mineral Products Quality Supervision and Inspection Center: "The national standard stipulates that the friction coefficient of 350 degrees should be greater than 0.20
