    Okay first time posting but need to see if anyone has advice or a solution. 2001 prius 195k on it. No codes relating to abs. No brake line leaks nor leaks at the wheels. Car bleeds off brakes at stoplights. I have diagnosed it as a bad master cylinder is that a correct diagnosis? That being said master cylinders for Gen 1s are discontinued and I dont see any aftermarket solutions. Does anyone know of a retro fit or should I do the "rebuild kit" that has a new piston seal and retainer (my worry there is a possible worn cylinder) or is my best bet to find one at a junkyard or a full blown parts car. Thanks in advance.
