BX2200 Brake Pedal Frozen

[Unpossible]

Hey - I've had my Bx2200 for 10+ years and it has been a great tractor.

However, lately I have been having a problem with the brakes. Last year, I had to reach down and pull up on the brake pedal to get the brakes to release. Now, no matter how hard I push or pull on the pedal, the mechanism won't move.

Looking at the mechanism, my best guess is that the torque tube that runs across the frame has rusted into the bearings and locked up.

Anyone else run into the problem, or have suggestions as to how to proceed in fixing it?

Thanks,
Jason

I would start with PB Blaster and soak the snot out of the bushings then when it gets loos tear it apart clean everything up and grease it and check your return spring as well

Looking at that assembly on Kubota parts site-

You should be able to disconnect the brake pedal/tube from both of the brakes by removing some keeper pin and pushing the connecting rods out.

Then you can see if the pedal/tube is locked up or if one of the brakes is locked up.

I spent the afternoon working on this without much luck.
I have disassembled the brake tube from the brake linkages that go back to the transmission.

It really looks like the break pedal tube is rusted into the bearing on the side away from the pedal.

I have soaked it in PB blast, but so far, no luck. I just reviewed the assembly drawings to make sure that I am not missing anything, but it looks like the assembly should just slide into the two bushings on the frame. When I push on the brake pedal, I can see the tube moving slightly in the bushing near the pedal, but nothing on the other side.

Any suggestions besides a bigger hammer?

Have you sprayed it with PB Blaster (or similar) penetrant? Give it a day or so to soak in?

It looks like the tube just slides into two bushings - so there should not be too much to do except get it to rotate.

I would start at the end opposite the pedal and take the short arm (#90 in the illustrated list) and try to gently drive the brake pedal rod out.

I can't tell how the bushings are held into the frame but it looks like they are driven into the frame? Perhaps you can drive the stuck one out of the frame and cut it off the shaft?

As a last result, cut the rod in half and drive both sides and bushings out of the frame? Cost of these parts should not be too much. Verify they are available before committing to this plan!

I've been soaking it in PB Blaster and smacking it with a large hammer.
So far it has moved an 1/8" or so, but I have really been smacking it.

So much so that it his distorted the end of the shaft (I will need to grind it down before it gets close to the bushing).

Just wish I could find a better way.

Thanks,

Other ideas on ways to destroy it while getting it out:

Drill through the end of the tube into the bushing at the open end of the tube.

cut the tube at 2 places near the inside of the bushings (removing the center section 2-3 inches) and drive the bushings out of the frame

start beating on the foot pedal face to try to rotate the tube inside the bushings - this could damage the frame where the bushings are installed.

That is about all I can come up with.

Good Luck!
