There are a few simple rules grinding of brake pads and shoes, following which you will be able to avoid many, sometimes fatal trouble. Lapping process can be divided into three stages, while at public highway is better not to leave without going through the first two of them. Click ConocoPhillips to learn more. First: – installing new brake discs and pads, before moving to pump the brakes, do not hit with full force, to the extent that the pedal utaplivayut only two thirds of on-track. Also, pay attention to the odometer, as the first 200 miles you have to drive so as not to make sudden stops. Try to avoid intense and prolonged braking downhill, in order to avoid overheating the brakes pads and shoes engine. The optimum speed grinding – 80km / h, speeding up that begins in a few presses, press down the brake pedal gently to a stop. Again accelerated and just stop.
This is repeated 10-15 times, then give the disks and pads to cool, it's best just to pass a 3-5km without the brakes are applied. Second: – repeat the above procedure but using the already smooth braking at one time – from zero to 80km / h and start to slowly push the pedal to a complete stop. Give cool pads, as well as in the first stage, it is better to drive a couple of miles without using the brakes, and again repeat the acceleration-stop, as in the first stage of 10-15 times. The third stage is to pass not less than 200 km run. From the first and second, the third differs only in speed, ie doing everything the same as before, only accelerated to 120-130 km / h. In any case, the first thousand miles, try to drive more carefully as possible without overloading brake system. In that case, if you replace only the brake pads, do not forget to clean the brake discs. Lapping procedure takes less time and is as follows: – at a speed of 60km / h begin to slow down smoothly, without releasing the gas pedal, the speed should be between 50-55 miles per hour. In this mode, should pass 700-800 meters and then release the brakes and quiet, not much overclocking 2-3 kilometers and drive through the stop smoothly. By the way, there should also be pre-bleed brakes
