I REPLACED BRAKE LINES TO THE REAR -- BOTH LINES FROM PROPORTIONING VALVE TO THE REAR WHEELS.I HAVE BLED THEM BUT CANNOT SEEM TO GET FLUID FROM RIGHT REAR WHEEL OK AT OTHER THREE.I DO NOT FEEL THE PRESSURE SHUT OFF VALVE IS STUCK TO THE REA AS I AM GETTING FLUID AT LEFT REAR & HAVE TRIED OPENING FRONT BLEEDER TO SHIFT SHUT OFF VALVE TO NEUTRAL POSITION AND I SUSPECT PROPORTIONING VALVE FAULTY? HOW CAN I GET INFO ON BLEEDING SEQUENCE.I WOULD DONATE BUT HAVE NO CREDIT CARD - I AM A LONG TIME TECHNICIAN WHO APPRECIATES HELP AS I WOULD DO THE SAME
