The brake system is a critically important system in any vehicle. It is prohibited to operate a vehicle with a faulty braking system, which, it its turn, is very susceptible to damage. The brake system is characterized by such problems as wear, damage or contamination (oiling) of the brake pads, wear, deformation, defects on the surface of the brake discs, loosening of fasteners, deformation of the caliper, sticking of the working cylinder piston, brake fluid leakage in the working cylinder, sticking of the main piston cylinder, brake fluid leak in the master cylinder, damaged or clogged hoses, pipelines, insufficient vacuum in the intake manifold, damaged vacuum hose. Malfunctions of the braking system reduce the braking efficiency, thus posing a danger to all road users. For this reason, it is recommended rectifying faults immediately after their detection.
