brakes giving me a headache!

I am having the same issue. I am going to use the vise grip on the rear line to see if that helps. I can't on the fron because they are Stainless. Has any one had issues with the adj prop holding air? Do I have to open it all the way when bleeding? The weird thing is I have no leaks. The fluid has not gone down.

I've had the prop valve stick and have the pedal feel like crap before. For those who haven't made the swap to ss, use the visegrip method to isolate where the air is, then take that line off and have someone push the pedal. You need to be watching the line. (Yeah, you'll get more air, but you're bleeding anyway..) If nothing comes out, then there's a problem. I've taken the prop valve apart, cleaned the hell out of 'em and put 'em back together. (**WARNING** not for the faint of heart!) Sometimes lightly tapping 'em with a hammer can unstick 'em, but that's a temporary fix at best. But it would help isolate in diagnosis.
