fxfymn Posted March 17, 2012 Share Posted March 17, 2012 Are you sure there is no bleeder on the upper wheel cylinders? I cannot recall seeing any wheel cylinder that did not have a bleeder, especially since the two wheel cylinders are generally the same part number.

joes mack Posted March 17, 2012 Author Share Posted March 17, 2012 yea no bleeders line from splitter going in top and line going to lower cyl coming out below it it only has two holes per wheel cyl. its a odd set up as the 74 chevy and the 78 f 600 that we have are set up with line from splitter going into bottom cyl and bleeder screw in top cyl. as i said earlier we have never changed a line or wheel cyl on truck the front brakes are set up this way also on all of the trucks Quote Link to comment https://www.bigmacktrucks.com/topic/23874-hyd-brakes/page/2/#findComment-108095 Share on other sites More sharing options...
Firemack Posted March 25, 2012 Share Posted March 25, 2012 One other issue can be the shoes are not adjusted tight enough to build up pressure, so if the brakes have not been adjusted for awhile tighten them up first then bleed the brakes per the process fxfym listed.

joes mack Posted March 26, 2012 Author Share Posted March 26, 2012 THANKS FOR THE REMINDER. NOW THAT YOU HAVE MENTIONED IT WHEN WE WERE BLEEDING THE BRAKES YOU COULD HEAR THE SPRINGS PULLING THE SHOES BACK AND IT SOUNDED LIKE THEY WERE GOING PRETTY FAR BACK. ILL ADJUST THE SHOES CLOSER TO THE DRUMS AND TRY IT AGAIN. I CANT BELIEVE THAT I DIDNT THINK OF THAT AS MANY TRUCKS AS IVE FOOLED WITH. I GUESS I MIGHT AS WELL CHECK THE SHOES AND IF THEY ARE WORE FAR ENOUGH PUT NEW ONES ON WHILE ITS STILL NOT IN SERVICE.
