The Stovebolt Site Forums The Shop Area General Truck Talk Front Brakes not bleeding.

Ok, I used the Mityvac today. Put Teflon tape on bleeder screws to make sure I was getting no leaks from around the screw. Connected the Mityvac like the maunal says. Pumped up to 18 PSI and it holds steady on screw. Open bleeder about 1/8 a turn I get a endless stream of ball bearing size bubbles. I open it up a 1/4 of a turn I get longer(like a hot dog) bearing sized bubbles endlessly. By endless I mean 1.5 hours on just the rear, with no good results. About 1/3 of a quart more wasted fluid too. All lines are tight, no leaks. Only thing I can think of is the wheel cylinders are sucking air or something... I have never had this much trouble... Opening up any more than a 1/4 and it just goes crazy like a shop vac hit the last of the water in a bucket(slurp, slurp, slurp pulses).



Could wrong size bleeder screw cause this? I took my old bleeders down to the local auto store. The outside of the screw looks the same, but the inner bore looks larger on the new bleeder, so maybe its releasing fluid faster than the lines can feel causing air???

At this point I think I am just going to order all new wheel cylinders and bleeders, unless you guys have a good idea to try??
