Kubota 9960. Hand brake problem...

[steveR]

Got a 2015 9960 with a knackered handbrake... Yes, it has got the gearbox brake, but I am not that fond of it.

I had a novice helping me a couple of weeks ago and he drove around with the handbrake on and has fried the brake....

Any idea on how big a job it is to put right please? Is the brake/lining inside the castings and requiring a strip down or split of the tractor?

Have been told it might be "inside the trumpet", not a term I've heard of before!

The brakes are in the trumpet housings, the castings bolted onto the transmission holding the back wheels. If he has totally fried them it would be well to replace the back axle oil and filters. (Unless it has a separate handbrake set up)

Aha, so that is what they are!

Hmmm, might be worth more investigation in that case. Thanks

Wonder is the parking brake separate to the service brakes in the trumpets though? Can't see any mention of parking brake(other than the transmission brake) in the parts diagrams. If the foot brakes are still ok but the parking brake isn't, surely it must have a separate band,discs or even shoes?

This is where I was confused, as of course, the tractor has the transmission brake operated on the gearlever. The footbrakes are fine. I assumed a separate brake system for the handbrake, possibly on a drive shaft.

Got a parts CD on the way, which may...or may not, help me Cant find a service manual on CD as yet.

Found a workshop manual online for the M8540 and M9540 which I'd guess use the same system as the later 9960. The conventional parking brake works on the main bevel pinion shaft and has a cam operating against pads and discs. It does look like the tractor will need splitting between the rear of the transmission and rear axle housing.
Seems a bit strange that the Kubota online parts list doesn't show anything to with this parking brake,unless it's because it's through a dealer(in the USA) and they're limiting what can be seen.

Bummer! Thought a split was looking increasingly likely.... this won't get done this side of the Winter.

Weird on the parts stuff that you have identified though.

Have to see if I can find an independent lad and avoid main dealer prices when the time comes. A few phone calls will be in order I think.

Just bear in mind this is for the M85 and 9540. Could be different but I'd doubt if it is......

@steveR
And another if it's any help....
