[OrrieG]

Pumped a few times? The original Orrie, my grandfather, rule of thumb was minimum 100 pumps with full return to work the air to the ends of the lines. I used auto bleeders and once I got one caliper right side up and a bend fixed that was causing an air pocket it went ok. the caliper bleeders need to be on the top to get the air out. On my 74 truck the calipers will fit on either side, I had two of the same with one mounted with the bleeder on the bottom. Also need to make sure you have a small space between the vacuum rod and MC so it fully releases.
