The way to see the X-431 Diagun brake conversion errors

Saying goes, run X-431 Diagun fast to stop the live many owners in the modification of the car in the braking system, put a lot of money, not only to improve braking performance, or the so-called Jiaogan, more importantly, must make love The car looks very kind, multi-piston wheel cylinders, increase the brake disc floating, high temperature brake pads ... can change all whole. In fact, for the modification of the braking system, a lot of owners are expensive is good, more is strong misunderstanding, Here we come to take a look at some of the problems often encountered in the modified brake.First clear, for the modification of the braking system, so the car easier to control, and shorten braking distance to improve the security of the vehicle is the ultimate purpose of the modification, and many owners in the modification of the car More is to look good, in fact through these gorgeous modified products, we more rational to look at the brake conversion, after all, the vehicle's braking system is an important component that relates to the safety, as for good or bad, we are not here to discuss.
Modified Myth # 1: change brakes, braking distance will be shortened

    
The modification to the car's braking system owners will feel the braking performance has been improved significantly, and even that will effectively shorten the braking distance of the car, in fact most of the results of a psychological hint that it took not less money1 / vehicle weight. The heavier the body, the greater the driving inertia, the requirements of the braking force is naturally higher. Grabbed like to be grabbed a run in the fat than like a scrag need more strength to the truth.

    
2 / tire adhesion. This is the most critical factor, the counterweight will be the front and rear of the vehicle body, suspension properties, tire properties, and road friction many other effects.

    
3 / braking ability. Contains two indicators, a brake efforts, the greater the intensity of the braking force, the stronger, the better the performance. The other is the performance of the thermal decay of the braking system, simple terms is in the braking process, the braking system will generate high temperature, and once the temperature exceeds the design limits of the product, the braking force will sharply even Zhidongshiling phenomenon . The thermal decay ability, excellent braking performance.

    
Modified braking system, is only one aspect of these factors in the optimization, there is no immediate effect stems from that.Say back to reality, usually on the original models for brake testing, and ultimately the factors affecting performance is not just out in the braking system, but the car weight and adhesion. Almost all models have emerged during braking ABS-start situation (most models almost the whole startup) well illustrates this point, we all know that only the braking force during braking beyond the tire and the ground attachment limit ABS will start, means that full braking, braking efforts completely above the above the grip performance, then how does not help efforts to increase braking.Often, A0-class car with drum brakes in the rear wheel drum brakes than disc brakes lower manufacturing costs, maintenance is also very convenient. A lot of people will think that drum brakes just in order to reduce costs to appear in such a small car, in fact, efforts to brake drum brake and not more disc brake, but the poor performance of drum brake thermal decay. it will be installed in the rear wheel. Manufacturers so the design is not just to reduce costs with no regard to the safety performance of the vehicle, the A0-class car weight (usually pre-precursor hatchback design makes the rear axle weight lower), the power is relatively weak, the braking system burden low, and full braking the front wheel brake load will account for more than 70%, so the speed itself is not high A0-class car, the rear wheel drum brakes and no problem. For example, in the previous generation Volkswagen POLO change models use rear drum brakes, the final score in the braking test 100-0 km per hour are maintained at 40 meters. Instead, modified disc brake use does not match or inferior parts, or improper handling construction hand, will pose a security risk, so we do not recommend the use of original small cars modified disc brake drum brakes.
● modified Myth # 3: blindly follow the trend, indiscriminate use of the multi-piston brake wheel cylinder with competitive products

    
By choosing a higher coefficient of friction brake pads and modification of high-performance tires, has significantly improved the braking performance, modification the Wheel Cylinder role more to match the higher performance X-431 Diagun  brake pads, brakes to cope with the heat decay phenomenon, it is more suitable to track traveling, because the the usually street driving difficult or almost does not appear on the brake system formed of such a high load condition. The most expensive part of the modification is also the braking system of the slave cylinder, usually each set the price should on a million pretty big calipers (Southern habit image known as abalone) attract many owners reason to buy at all costs. Multi-piston design can make the braking efforts more evenly transmitted to the brake pads, not only the braking force can be enhanced, larger brake pads can also play a role to improve the cooling efficiency. The high-performance brake wheel cylinder with lightweight advantage, reduce unsprung mass further improve handling performance.
