Modified car tuning knowledge of Nissan Consult 3 brake

No matter what kind of car, the brake system is to protect the most important part of the traffic safety, more essential, powerful brakes with high-powered modified car fans, after all, the car is light strong acceleration forces can not easily stop under, will lead to serious consequences. Therefore, before further enhance the speed performance of the car, we must first to enhance the performance of the braking system.

    
Let talk before conversion to understand the theory of the brake system, a 200hp horsepower, weight 1300kg car accelerates from a standstill to a speed of 100km / h may take 9-10 seconds, but the same car in violent brake case by the speed of 100km / h deceleration to a complete standstill, it only takes less than 3 seconds, indicating that the negative power of the braking system can be several times larger than the power of the power system. In physics, energy is not going away, it will only be converted from one form to another form, such as the kinetic energy is converted to heat, light, etc.. In the above example, a large number of vehicles "momentum" is the brake system at the moment all converted into heat energy, accumulated in the brake member, wheels, and road surface. And, if the brake without locking the wheels, then most of the heat absorbed by the brake parts. If the heat can not be quickly lost, would lead to overheating of the brake pads or brake fluid, making them lose their most important role - security, modified braking system, every aspect and temperature related.
Brake pads


    
Original brake pads due to the care to the cost, durable, the cleaning (Brake powder) and the low-temperature efficacy requirements, generally not very high coefficient of friction (mu) (about 0.4 or less), but mostly not withstand more than 300 ℃ temperature, after repeatedly occurs performance of a recession. Therefore, the replacement of the high-performance brake pads is the first step in the modified braking system. To select high-performance brake pads do not do too large mu number of ultra-high temperature, high friction coefficient makes braking action becomes too sensitive in slow motion, every time you touch the brake pedal will make the car's passengers off their feet, in addition to brakes will wear increases reduce life expectancy.
