 Date: 07/31/22 20:32 Re: Anyone know what this does? Author: trainjunkie Load sensor. Braking pressure changes depending on whether car is empty or loaded.

When the car is empty the brakes are not applied as strongly when the car is loaded. The wheels would slide with a strong brake application. the plunger is forced down to the frame of the car when loaded giving a stronger application.

There is another small air reservior on the car that puts air into the brake cylinder when this valve is opened. Or at least that's how I think I remember it.
