Massey Ferguson 7495 VT park brake problem

[elvar]

Hi. I have a MF 7495 vt and the park brake goes on and off when switched (light goes on and off and it really releases the brake when off), but it seems that the information doesn't get to the computer and the tractor does not drive when selected. No fault comes up, it just doesn't drive.

Check for debris in the linkage on top of the axle, it might not be releasing all the way to trigger the sensor

The handbrake is normally mechanical with a proximity sensor on the brake linkage on top of the axle I think. When you say that it releases when the light flickers off, I am inclined to think that you are talking about the transmission lock operated by the tab on the Power-Control lever that was optional equipment. Am I correct?

Hi yes that's correct. Electric control that controls the brake.

Thank you. Was not lucky enough to solve by that way.

Not as simple to diagnose as the handbrake. It is obviously either electrical or the actuator that sits on the gearbox somewhere, which is no help at all to you I'm afraid.

Yes, mechanical would do better. But thanks anyway

Did it work?
