But is not immutable and frozen coefficient of friction brake. The brake pads of the different formula and processing technique of different content, the friction coefficient is also different, more important is the same block brake skin friction coefficient will change with the temperature changes, it is not a fixed value. Testing professionals, brake must be in a special instrument measurement in "coefficient of friction temperature ladder" on different temperature points, so as to draw a continuous "temperature coefficient of friction" curve, this curve is the brake important reference data sheet. Sounds like a graduate work, very vexed? Actually any producers won't show you the brake side, as the ordinary consumer, you also need not care too much, as long as the actual driving and simple means of testing, you can judge whether the use of this set of brake pads. The modification of the front is directly tested in this method, the method to say later. In short, modified brake pads first is the hope and the friction coefficient in any case should be better than the original factory.
If you are a clean driver, but also the average 60km/h per hour, no matter how the brake, the temperature of the brake pad is only 100 DEG C, brake original enough to use. But if on the highway, from the speed of 100km/h emergency brake to 20km/h, the temperature of the brake pad is raised to 150 DEG to 200 DEG C; if the highway 200km/h, see the front road red reflective cone and the emergency brake, temperature of about 170 DEG to 220 DEG C; if mountain road with a brake, then the temperature is about 250 C; if you are a race car drivers or is like flying in the city "criminals", so frequent braking and rapid brake force will cause the brake upgrade to 300 DEG -350 deg. These situations, your original factory brake it may not be able to meet the security needs!
