In case of cancellation circuit brake system free lift increases. In case of failure of the primary circuit, the primary piston is based on the secondary piston and rod brake booster brings the latest in motion by a mechanical connection (I). Fig. 6.5. Job master brake cylinder with a failure of the primary and vtoroichnogo circuit brake system
Upon cancellation of the secondary circuit, the secondary piston rests on the limiter at the end of the opening of the cylinder, then the pressure rises in the primary circuit (II) (Fig. 6.5).
-Lock braking system ESP MK60 Fig. 6.6. Schematic diagram of the anti-lock braking system MK60
ESP is currently the most modern active control system and prevents the emergence of critical situations in the movement at the beginning.
Anti-lock braking system ESP MK60 Astra-H includes the following systems: - Anti-lock braking system (ABS system); - Traction Control System (TCS); - Program electronic stability control (ESP). and has the following main functions: - Logical control scheme understeer (UCL); - Control braking force when the motion in the rotation (CBC); - Trailer stability control program (TSP); - Integral control body (ICC). Depending on the version of equipment, anti-lock braking system ESP MK60 may also have the following additional features: - Detection system pressure drops (DDS) controls the loss of tire pressure through the wheel speed sensors in the event of loss of tire pressure monitoring (TPMS / DDS). - Hydraulic power Brake Assist (HBA); - Assistance when starting on a slope (HSA) to prevent slipping back into the car for two seconds, thus facilitating moving off on a slope. The following table contains general information about using different versions of systems installed in vehicles Astra-H.
