2001 M 750ss REAR brake seems to stick off and on ?

[H-2 CHARLIE]

  I just put a new rear rotor and EBC brakes on,i did clean the piston and used a light syn greese to be sure it moves freely and it sticks or drags real bad almost locks up . Now when i tap the rear twice it releases then i dont use it ,it did this a few times before i changed the new brakes and rotor . they dont make a rebuild kit a whole new brake cal. is $175 .WTF .

You checked that the piston in the master cylinder isn't sticking in its bore?

My 996 did this and eventually caused the rear calliper to vibrate itself off and drop into the rear wheel after it had sheared the mounting bolts off...

Nice RD350 ypvs too
