M1083 Treadle valve removal advice.

[Shiflett]

I need to rebuild my treadle valve (brake valve) and I’m having trouble removing it.
Seeking advise from anyone who has rebuilt one.

did you remove just the valve or the pedal and bracket as well?

if the whole assembly, did you have to disconnect the dash or remove the steering wheel?

A0, A1, A1R truck?? (what year is it)

Maybe they are all the same when it comes to Treadle Valve .... best not to assume and include more truck details?

Thank you. I have fixed the issue. My problem was the park brake valve would “pop” on every time I hit the breaks medium or heavy. Turns out the treadle valve exhaust hose was clogged. I’ve temporarily run another one for now.
