Brake valve ( paddle valve)

Does anyone have experience accessing this valve for service. It is mounted up against floor, and very difficult to access. I was told it has to be accessed from inside the coach , by disconnecting the pedal assembly and removing the carpet, etc.  Has anyone done this. It is leaking air. Thanks for your input.

The treadle valve is not easy to get to or replace.
On the inside of the coach you will find three bolts in the foot pedal assembly which go through the pedal bracket and down through the floor securing the treadle valve to the floor and bracket.
The easiest way to replace the valve is to remove those three bolts which will allow you to get the valve down far enough to remove the air lines and change the valve .
There are a couple of common faults mostly caused by dirt or corrosion.
Often the foot pedal will stick on its hedge point or dirt will cause the plunger to stick or jamb.
The brake valve should be a bendix E12 .
It may be a good idea to disassemble the valve and clean and serviced it
