6030 JD Kills When Applying The Left Brake

It turns to the right just fine when using the right brake..It turns to the left just fine too as long as you dont use the brake.There is nothing wrong with the rear end.

It must be a problem in the brake system?

>Individual Brake Won't Release:
Right inlet valve leaking.
Left inlet valve leaking.
Housing orfice plugged.

>Both Brakes Engage When Individual Brake Is Applied:
Operating rod guide stuck down on opposite brake.
Equalizing valve or packing failure.

>Brake Pedal Kick:
Air in system. (Bleed brakes)
Brake disk warpage.

As one brake is applied the equalizing valve of the brake opens in the first 3/4 inch of pedal travel and same if both pedals are locked together applying equally. Another 1/8" of pedal travel opens the check valve disk and hold check valve closed. Pressured oil then flows to the wheel brake cylinders pushing the pistons and pressure plate pads against the brake disk that is splined to final drive shaft. Dirty oil, plugged orfices, failed springs and check balls in the brake valve can all cause that too and worn pedals and linkage won't help either. Get the valve assembly working right first and then determine if rest of brake system is too worn or needs more attention.
