Getting all the air out of new lines to the rear with a small bore m/c is very difficult. All you do is move the air bubble(s) back and forth in the line. We always start the bleed process at the furthest brake and evacuate the lines with vacuum.
What system or tool do you use to bleed the lines with vacuum? I think HF has a tool for that, but I don't want to waste money if you have a DIY method.
HF brake bleeder - but is it junk or good? Thanks
