Brake Bleeding Nightmare

[youngcuda]

Hey SFEBody, what is the universal kit that you refer to in your post? Mfg, source, cost?? It may solve my issues. I have had problems with my brakes on my 70 Barracuda since complete restoration and rebuild. New everything as far as brakes concerned (MC, Booster, lines, drums, components, etc.) I have bench bled the MC, adjusted the booster pushrod to MC, and bled all 4 corners several times. With the engine off, I can pump up the brake feel. As soon as I start the engine, the pedal goes down almost to the floor and braking action is almost nil until I get to the end of the pedal travel and then it is nearly immediate full braking action. Any ideas by others???

Youngcuda.
It could be air in the system. Give the pressure or vacuum bleeding a try.
I vacuum bleed all the time it does work very well and I can do the job by myself.

When using a vacumm bleeder i put white sealant around the thread on the bleeder screw as the the bleeder tends to suck air in from around the thread (the path of least resistance ) rather than sucking fluid once all the bubbles have gone follow up with a pump ,hold & release method if pedal is still soft check rear brake pad adjustment

This is a great tip on the coated bleeder screw. I saw this recently doing my son's Tacoma brakes. Kept getting bubbles and would have been there forever until I realized that opening the bleed more to get more flow was allowing air to come in the loose threads.
