Here's what I do: Button on top of proportioning valve has to be pressed while you are bleeding.I've fiddled in a clamp. Start from the back brake furthest away. Get a jar and put some clean brake fluid in it. Barely crack the back bleeder and attach a clear hose/tubing to the bleeder,nice tight fit. You have the end of the hose submerged in that jar of brake fluid.Open the bleeder just a bit more. Now pump the brakes not all the way to the floor like about 3/4 of the way. Watch the tube till it flows clear. I have actually pumped the brake by hand and watched the flow.Tighten bleeder without disturbing the hose. Other back bleeder next then move on to the front doing the furthest from the master first. So...The hose is in the brake fluid and it can't suck air back only fluid. Make sure to watch your fluid level in the master as you go. Another thing you can do if the fronts are being hard to bleed is get a pump type oil can,attach the hose from can to the bleeder and pump the air bubbles out/up from the bottom. Might have to drain some fluid out of the master as you go. This works really good w/a Hyd clutch. Sounds a little complicated but this has always works for me while I bleed them by myself. But a helper would make it easier. That was a mouth full !!!!
