IN THE LAST MONTH I'VE REPLACED THE BOOSTER, MASTER CYL, FRONT PADS & BACK
SHOES. YESTERDAY I CHANGED THE WHEEL CYL ON REAR DRIVER SIDE. I,VE BLED
THE BRAKES. THE PEDAL SEEMS FIRM UNTIL I START THE ENGINE THEN IT GETS
SOFT AGAIN. ANY IDEA WHATS WRONG ? I DONT SEE ANY LEEKS.THIS IS ON AN '83
FORD F-250.

phips, thanks for your reply.Would it be a visable fluid leak or a pressure
leak? I cant see any fluid. Im wondering if I need to take the master cyl
off and bench bleed it again.
