flem New Guy F Joined: Feb 2011 Posts: 19 Davisburg,MI	I've posted a couple times with brake and clutch questions, now trying to follow up on the set up on my truck but my big bolt has some strange anomallies - 1st is has the wagner airbakes which now since I fixed the pressure release valve is pressuring up to 120psi and holding it. 2nd -doesn't have a driveshaft parking brake, is because of the airbrakes?? 3rd does have cable operated brakes on the rear drums connected to the park brake lever 4th - has a cable operated PTO (this from the orange color is obviously from a later truck) looking for thoughts I've included a link with pics http://s1198.photobucket.com/albums/aa460/jflem3/ Last edited by flem; 03/30/2011 2:13 AM. 50 chevy 2-ton dump 71 C-20 Suburban 402/400 72 C-10 Suburban 350/3-speed

It looks like you have a Air Chamber coupled to a hydraulic Master Cylinder mounted on the frame rail.
