I have been trying to bleed my brakes with no success... bled master cylinder, then opened one bleeder at a time with a line into a bottle w/ fluid, pump the brakes slowly. Get plenty of fluid at 4 wheels. When I close all the bleeder valves I have no pedal. There are no leaks anywhere and I have absolutely no clue what is happening. Any ideas?

Perhaps bleed your brakes the proper way, with a vacum brake bleeder, http://www.sears.com/sr/javasr/product.do?cat=Mechanics+Tools&pid=00921021000&vertical=TOOL&subcat=Automotive+Specialty+Tools&BV_UseBVCookie=Yes

I had a Mustang that gave me the same issue, turned out there was a ton of air in the system I wasn't getting out.

Sometimes there is a ton of air in the system. Try starting out with the gravity bleed then start with the RR wheel, LR, RF, LF. Make sure to keep the pedal down steady when you crack the bleeder open.

You need another person or stick to pump bleed. Sounds like air is sucking back in when you are bleeding. To pump bleed you need to crack open one bleeder, slowly depress pedal, CLOSE bleeder, then lift off pedal, open bleeder and keep repeating till no air bubbles. Then move on to next bleeder. Generaly accepted method is farthest first although I've seen other recommendations.
I once made a stick cut to length to put between the steering wheel and pedal so after depressing the pedal I'd put the stick in and get out and close the bleeder, then take out stick/open bleeder and so on. Time consuming but I work alone a lot so have to be resourcefull. now I use a Motive vacume pump (about 40.00) which saves a lot of time. Before any road track event replace fluid unless it's really new.

Bleeding can be a Real PITA and I've used every method imaginable and at one time or another one of them would not work for whatever reason so I had to try a different tactic. About 12 years ago I bought a kit called Speedi Bleed from my Snap On dealer and it's been a great tool. If it is within your budget and you think you;ll need to bleed often enough I would recommend that you seriously look into one. After 12 years of use i needed to replace a part just recently and found them on the web here. http://www.speedibleed.com/.

Does your system have a brake differential valve under the master. Not a proportioning valve differential safety valve. It might have been pushed to one end closing off half the system.
