Brake Fluid Expansion Tank with Integrated 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 and a second lower one for the charge pump supply.
The brake fluid level switch is incorporated into the tank. 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 DSC responds by switching off the ASC/DSC functions.
Normal braking and ABS operation is unaffected.
