Chris, thanks for the beer motivated info. I have been told that these are in fact 914-6 rear calipers. I have taken them off and will send tomorrow to Eric in Salt Lake City for a rebuild. Everyone on 914 World says they are the real 914-6 caliper so I am assuming that is the case.
I do not track the car and the front brakes are custom CNC brake calipers made down in southern CA.
I do have two brake master cylinders up front and two fluid holders so they are separate from each other. Behind the brake pedal I can adjust how hard each one is coming on which in theory would be my prop valve correct?
I couldn't find any pics of the front brakes... I will take one if needed but they are 4 piston calipers I think. Let me know if you have any other input and thanks for the compliments on the car.
Here is a pic of the power plant.
Regards,
Bryan
