Too low level of brake fluid?
If overlays of disk brakes are already a little erased, the tendency to lowering of the level of liquid up to the lower mark is looked through; if they new, liquid level again exceeds the top mark. This absolutely normal phenomenon as at the erased slips the moved forward are a little farther pistons of a disk brake leave the bigger volume which is filled with brake fluid in cylinders of brake supports. The situation becomes critical when in a tank the level of brake fluid falls below a mark of "mines". As it does not evaporate and is not spent, that is a leakage place. Quickly find out the reason, the brake pedal did not refuse yet! Having added will be eyewash!
