Reservoir

Part number: 8646006

The Brake Master Cylinder Reservoir uses a magnetic sensor to detect the brake fluid level. This is a 2-wire sensor with only two signal states: ON or OFF. On means there's brake fluid in the reservoir, OFF means low level or no brake fluid. It is not possible to replace the sensor alone, one needs to buy the reservoir.
