<DIV>My BE master cylinder is backflowing into the reservoir when the pedal is released; I can see it. The pistons are Gerard's; the rubber bits are new. I am not sure what else is new, as it was rebuilt when not needed by the same mechanic who advanced the cam 18 degrees.</DIV>

<DIV><SPAN id=xc8a624702aab488fa2a7594d1c63f964>Long ago, there was a problem with the mushroom-shaped plastic bit on the outer end of the spring. That was replaced by Gerard. Also, Gerard and others have suggested that the rear brake springs can suck up fluid if the pads are loose; with the emergency brake set, that should not happen.</SPAN></DIV>
<DIV><SPAN></SPAN> </DIV>
<DIV>It seems to me that there can be only two causes: 1) The check valve has failed. 2) The push rod is the wrong length exposing the hole into the reservoir when it should not. </DIV>
<DIV> </DIV>
<DIV>Any advice?</DIV>
