Brake-fluid levelThis was the right answer

You should carry out frequent checks on all fluid levels but particularly brake fluid. As the brake pads or shoes wear down, the brake-fluid level will drop. If it drops below the minimum mark on the fluid reservoir, air could enter the hydraulic system and lead to a loss of braking efficiency or even complete brake failure.
