Default Re: NO to little BRAKES

Only with the engine running did I lose all brake pressure. I have NO LEAKS whatsoever. Any advice is greatly appreciate.
I would say the master cylinder has a leak internally. Have someone push on the peddle while you look inside the open brake fluid reservoir you might see the oil getting disturbed near the bottom of the tank as it comes back through the seals.
