Well I'm still working on my 69 swb 4x4 w/ drums all the way around and can't seem to get any brake fluid to go through the brake lines . I think I got a bad mstr cyl from checker ($14.00)
I bench bleed it until there wasn't any more air bubbles and put it on and no fluid going through . I think I'll get my money back and go for a NAPA unit ($21.00) Maybe I'll have better luck !!
