GMC, brake fluid change in Zevulun.
The brake fluid should be changed at the intervals recommended by the automobile makers. To change the fluid, the hood is opened and all the old brake fluid is removed from the brake reservoir with a syringe or squeeze bulb. After that, the brake bleeder screw is pumped with the help of a syringe. At the same time, it is required to start the engine, press the brake pedal and fix this state. With the help of the bleeder screw, part of the brake fluid is released and the bleeder screw is pumped again. This is repeated until fresh brake fluid comes out. When this happens, the process can be considered complete. As a rule, the brake fluid change is performed by two specialists.
