574 BRAKE PROBLEM

Posted by MARK on May 28, 2002 at 19:46:26 from (209.209.132.120):

MY 574 DIESEL BRAKES DO NOT HOLD WELL UNLESS I PUMP THEM.IT FEELS JUST LIKE OUT OF ADJUSTMENT ON CAR DRUM BRAKES.SOME OF YOU GUYS OUT THERE ADVISED ME HOW TO BLEED THEM. HOWEVER, I FOLLOWED THE LINES FROM MASTER CYLINDERS ALL THE WAY TO WHERE THEY GO INTO THE SIDES OF THE TRACTOR.THERE ARE NO BLEEDER SCREWS.SO I CRACKED THE LINE NUTS WITH ENGINE RUNNING,BRAKES APPLIED.NO AIR AND VERY WEAK DRIBBLE OF FLUID.HOWEVER THE BRAKES WERE HOLDING WELL BECAUSE THEY WERE PUMPED UP.
BUT AFTER I TIGHTENED THE NUTS UP AND RELEASED THE BRAKES THEY STILL DO NOT HOLD.(UNLESS I PUMP THEM).THERE IS A WHITE PLASTIC RESEVOIR ABOVE THE MASTER CYLINDERS WITH 2 LINES FROM BOTTOM AND 3 IN THE TOP (1 WHICH VENTS(?) TO A POWER STEERING LINE).THERE ARE 2 HIGH PRESSURE LINES COMING OUT OF EACH MASTER CYLINDER,1 GOES TO REAR OF MASTER CYLINDER AND OTHER GOES TO REAR SIDE OF TRACTOR,BUT NO BLEEDER SCREWS THAT I CAN SEE.
SO WHERE DO I FIND THE BLEEDERS? OR DO I HAVE ANOTHER PROBLEM? THE PROBLEM IS WORSE WARMED UP.ALL OTHER HYDRAULICS WORK FINE. IS IT POSSIBLE MY MASTER CYLINDERS ARE WORN OUT AND NEED REBUILT?
THE LEFT IS WORSE THAN THE RIGHT.WHEN PUMPED UP,EITHER PEDAL IS SOLID AND WILL LOCK THE WHEELS
EASILY.SINCE I HAVE A VERY HILLY FARM, I NEED BRAKES!
THANKS FOR ANY HELP OR IDEAS!
MARK
