Brake pressure differential warning valve

[seniorchristo]

My brake differential valve is leaking due to a bad o ring. This is a square shouldered o ring approximately 3/8" OD by 1/16" X 1/16". Has anyone rebuilt one of these?

Thanks

I redid mine about 5 yrs ago. I have a lathe and made new shuttles and cut grooves for standard O rings. No trouble so far. Not much help but it can be done. Gary

Thanks Gary

I got it working with another o ring from a rusty old spare valve
I wouldn't want to have to buy a new one!

I think that's what prompted me to fix mine too. Pretty amazing price I think. Gary

I deleted mine when I deleted the servos. If there's ever a problem with one of the brake circuits, I doubt that I'll need a light to tell me so.

Yep at that price you might as well get the extra benefit by buying a small lathe instead
