New HEL lines came in on monday so I figured I'd whack em on today being my day off. Cut forward a good 5hrs and I can't get pressure on the lever. Doing the whole "open bleed valve, squeeze and hold lever, close valve, release lever" was working fine but after I got a bit of fluid out of the calipers, opening the bleed valve would suck some of the fluid back in. Stumped I turned to google which suggested to crack the banjo, squeeze so some fluid comes out whilst tightening it back up (with the valves closed of course). Going back to opening/closing the valve pulled out some air then fluid at a steady rate but then it was back to getting sucked back in when I opened the valve. Obviously I have some air somewhere in there but I have nfi where. I've cracked all 3 banjos (master cyl, left and right calipers) and let a bit of fluid dribble out which helped a bit but still nothing. Every walkthrough/youtube vid I've seen says to start at the cylinder's bleed valve, yet I don't have one so the next step is the calipers. Also I've been really anal and kept the reservoir near full the entire time so as not to get any air in. Is there something wrong with the way I was priming? Or is there a diff method that works better when you've just replaced the lines? Saw one suggestion of attaching a decent length of hose and just sucking the fluid through which doesn't seem too stupid but I'll have to leave it for tomorrow (or friday).
