In Reply to: how can i tell if the brass fitting is a prop. valve posted by clueless [108.162.210.234] on Wednesday, September 07, 2016 at 11:03:46 :
blowing on it i get no resistance either way
seems if it were a proportioning valve i would get resistance blowing out and if it was a residual check valve i would get resistance blowing in?????????
on the same note the ford mcs in ref that have a proportioning valve are disc drum mine as i said is ford 96 f450 disc front and rear
