I have a 47 3/4 ton Chevy that I cannot get brakes without pumping pedal a few times. The question is, does this model have wheel cylinder bleed screws? This one does not have one on any wheel so I bled them by loosening the line where it goes into the back of the cylinder but I don't think this is getting air out of the wheel cylinder, only the line. It looks like there is a place where a bleed screw should be but they are not there. Are they all missing, could they be broken off or is there something to buy that fits in there to bleed them? There is no fluid leak on any wheel. thanks for the info!!!! slowgoer
