Hi. I'm new to Porsche 914 ownership so please go easy on me. I have owned vw splitscreen buses for 30 years and restored loads of them though.
I bought a California 914 a few months back that is running fine now but had been sitting for a number of years needing the brakes restoring as all four callipers had sized and master cylinder leaked. I replaced all four callipers with rebuilt OG units from a reputable USA supplier together with a new master cylinder. I've bled the system 4 times using the easy self pressure method and combined traditional two person method and also combined both together as described on forums. I get clear brake fluid at each wheel with no bubbles but I have no pressure at all at the pedal. It goes straight to the floor. I've read every brake thread on this and other forums and can't find a solution. I have not replaced the pressure regulator as they aren't available her in the uk but would that cause zero pressure? I'm thinking there may be an issue with one or more of the callipers. I've got no leaks I can detect on the system. I'm stumped and lost for what to try next? Any help would be appreciated. |

Are all of your bleed valves pointing up? Easy mistake to make when you have taken the calipers off. Just asking.

"Bleed valves pointing up"?! Not sure I follow, all my bleed valves are horizontal and can only point one way when installed.... Are all of your bleed valves pointing up? Easy mistake to make when you have taken the calipers off. Just asking. They are on the upper side not lower side of the caliper, correct? ? |

My 74 has 2 bleeders on each caliper, there is always one on the top, but one on the bottom also!
