randomly lose brakes

[justtorchit]

so last weekend i was wheeling and the pedal would randomly go to the floor at somepoints, then it would come right back to normal... i have no leaks and master cylinder/ all calipers are brandy new.

now i cant imagine it being the brake booster, because that would make the pedal stiffer... (correct??)

anybody ever have this problem before, any ideas??

cut a hole in the floor so the pedal can go down further

no, that was my idea for the gas pedal, but if you make the hole large enough it would work for both i suppose.

good ball ventilation as well.

even though its brand new my bet would be bad master cylinder. did you bench bleed it correctly ?
