Tandem Master Brake Cylinder

1999 BMW 328i 4D Sedan, StandardSECTION Tandem Master Brake Cylinder

The MK60 system uses a tandem master brake cylinder fitted with central valves as in other DSC master cylinders. The central valves allow fluid to be drawn through the master cylinder during ASC and DSC regulation. The hydraulic circuit is divided front/rear.

An inlet for pre-charge pressure is no longer used since the charge pump has been eliminated from the MK60.

Both brake pressure sensors are mounted on the master cylinder.
