M7060 with bad brakes!

[romoni]

Hello everyone, I don't have the Branson anymore, I got myself a Kubota M7060 12 shifts, 2016 with an M21 loader and snow blower, 1340 hours on it, really nice tractor but. The one and only problem with it, and it is quite a serious one is faulty travel brakes. I have to pump the pedals to get brakes, the right one will go right to the floor on the first pump, gains three inches on the second pump and is good after the fourth pump. The left brake pedal will not go all the way to the floor on the first pump but stops three inches from the floor and is good after the second pump. Once foot ¨primed¨, both brake pedals stay within half to three quarters inch from their resting position with no sponginess OR sinking with applied foot pressure, at that point both brakes will positively lock the back wheels. As soon as you release the pedals they are both instantly ¨deprimed¨ again. The oils and filters were just changed and trans oil was replenished with Kubota UDT. I have been over forums and there is not much on this as there seems to be very few cases. Since both brakes will sit pretty after being pumped, could the master brake cylinder be the problem? Any help would really be appreciated and merry Christmas to all!

It’s possible. Hard to tell without driving it and more info. My bigger kubotas have a lot of sensitivity on the brakes if the master cylinder reservoir is even a little low.
I replaced a master cylinder on my 126x this summer. It had a bad leak. But mine is a 2011 with 3,000 hours.
They should work with a lot less hassle than you’re describing. That’s not a lot of hours to be having those problems.

Have you attempted to bleed both RH & LH brakes? It appears from viewing M7060 parts catalog that brake master cylinder is supplied hyd oil from power steering control valve. Bleeder valves are on each side of trans case.

No reference to a M7060 in that link. Seem to be only older models.

From what I found out the master cylinder has a constant supply of transmission oil.
