Hi all,

So my 95 psd seems to loose brake pressure. When its not running and I pump it up it holds its pressure just fine but when I start it they hit the floor. Driving the truck I have to pump it up to get them to work. It looks like the booster has been replaced, I bleed the lines and replaced the pads and shoes and the lines all look good. No lose of fluid and the vacume pump seems to be making good vacume. I havnt replaced the master yet. Any advise is appriciated.
Thanks!

 

ok. from the vac pump, follow that hose back to the fender. there is a splitter block deal. make sure all those lines are on good. it does sound like vac pump tho.
