1594 Trailer Brake

Post by des » Fri Aug 03, 2018 1:02 pm

Hi,
My 1594 has trailer brakes which intermittently do not work. Is there any known issue or does these valves give trouble. The brakes on the tractor itself are working fine with a good brake pedal and there is no air trapped in the system. Please advise.

Thanks,
DM

It maybe the spool valve (it acts like an ABS) it sticks so the spool does not allow hydraulic oil to pressurise the trailer brake system. The spool can be accessed by removing the end cap, with the bleed screw on, and remove the spool and clean it up. Don't forget the brake will need bleeding after re-assembly.
