I am building a streetrod. Last summer the brakes were the 'item' and I bleed them and checked for leaks...none were in evidence...all summer I watched the fluid chamber to note any leakage..none
This spring I go out there and the reservoir is empty!
I searched for leaks again and could not locate any...I put more fluid in and now for a week it is staying full
Any ideas as to what is going on?

did you use a power booster? often if no leak is found they will leak inside and you will not see it. this would mean the leak is around the plundger going to the master cylinder.

Yes there is a power booster and I am aware of their tendency to capture fluid. But I have not as yet checked it. Funny thing is the brakes were not touched either all winter or recently I would expect a leak into the booster would need plunger actuation...anyway I will check but am at a loose as to how to determine this accumulation into the booster withour some sort of disassemnle...any ideas?

Ya know I bet when I start the engine ...if the fluid is in the power cylinder it will go into the intake manifold and while it may smoke a bit it will reveal if the power booster is the problem.
