Brake fluid level sensor

Brake fluid level sensor
Hey everybody! I just replaced an ECT today and noticed the wiring harness below my master cylinder was wet and the wetness continues down the shock mount. It seems like brake fluid and the connector from the brake level sensor is damp, as well as the cruise harness, but the nut is dry. The bottom of the master is wet but the tank doesn't look cracked. I couldn't find any place underneath for the master to leak. Does fluid come out of the brake level sensor and how the heck does it come out? I pulled the plug and could get it to slide out...
For some strange reason I have a feeling Ford SHOULD recall these sensors because it seems like these have the same problem as gassers with leaking... I know the diesel doesn't have constant power unless powered on, so I guess if the sensor lights a fire, I'll get roasted instead of my property....

Level Sensor
Pressure Switch

Get the sensor replaced. That's the one that ford has had a problem with. On the gassers, it's on a recall because it has power to it all the time even while parked in your garage and has been known to cause fires. On the diesels, no power until the engine is running, thus no chance of fire while parked in your garage and burning up your house or you. HTH's Lee

Sorry my description was confusing, I was typing and thinking instead of thinking then typing haha. Both sensors are wet somehow, but the only one that can catch fire if it leaks is the pressure switch. I am going to replace both, provided the level sensor even is removable... Just can't figure out how to get it to come out

The level sensor is removable, but does not go into the fluid directly. IOW, the sensor mounts in a pocket under the fluid reservoir. The proximity of the float, when low, to the sensor activates the warning light. If it is actually leaking in this area, it would be the reservoir, or other outside source, and not the sensor.

Well, just wanted to button up this thread. The reservoir was leaking at the black seals only when hot. Master cylinder was replaced, as nobody would sell me the tank and seals... Hope nobody else has to deal with this as it was a pain in the butt. Make sure to check your cruise sensors as mine was leaking as well!
