E46 Traction and Stability Control Systems

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.

Expansion Tank and Brake Fluid Level Switch

The brake fluid expansion tank

has internal baffles that reduce

foaming during return pump

operation.

The expansion tank includes a

pick-up tube for clutch master

cylinder fluid supply.

The brake fluid level switch is

incorporated into the cap. The

switch is a reed contact switch.

If the brake fluid is at a sufficient

level, the switch is closed and

switched to ground.

If the fluid level drops below a specified level , the reed contacts open and the MK 60

responds by switching off the ASC/DSC functions.

Normal braking and ABS operation is unaffected.
