Hi, I’ve a Massey Ferguson 6490 (2005) tier 2, when using the hydraulic spools the tractor is activating the trailer brakes but not the tractor brakes. So when tipping a trailer the brakes are locked on or using the floor on a dung spreader. Doesn’t happen every time but happens most of the time.
The tractor is twin flow load sensing, we have replaced the priority block, the trailer brake valve, the master cylinder and the accumulator associated with the master cylinder.
We are not sure where to go from here any idea would be appreciated
