4310 brakes hanging

[chickenman]

does any one have a problem with brake lockup?

hi chickenman . yes the brakes have been known to become stuck on 4310s but Im pretty sure it would drive thru the brakes or at least lug the engine down. I dont know if the park brake switch would disable the drive or not.

unfortunately I'm trying to do a calibration on the electronics and I need the wheels to spin freely

so I have to get the brakes loose to calibrate the controller, until then it's a paper weight and going nowhere

you may have to disconect the brake rods at the arm that is on the sides of the axle housing and knock the arms back toward the rear if they are sticking . when the cal is sucsesful the rear wheels will just move slightly at forward and revese bottom of travel then the lite should stay off. yes i have been through all this before so just hope Im being helpful .

that is what i thought i'd have to do

take the rubber hammer i carry on the tractor to them

what model did you have to calibrate, did it have the flywheel sensor?

One brake stuck on my 4210. After working it loose with a hammer, wrench, and a lot of penetrating oil, I hooked a ver strong bungee to it and to the back of the tractor. This helps to disengage it. Everytime I hop on I would also give the shaft a good coating of penetrating oil.

There are helper springs on each side's brake bellcrank. They attach to the
bottom ROPS brackets. The springs are quite strong, but can rust up
or get knocked off. Are they missing?

I just bought new ones last week. I wouldn't call them "quite strong." I was disappointed in the strength of them. I think they're just there to reset the 1" of free play you're supposed to have. They don't seem strong enough to disengage a stuck brake. I spent a lot of time on the brakes that last couple weeks.... I wouldn't expect them to solve any problems with the brakes except making the pedal feel good during initial engagement and at the end of release. Sorry for disagreeing with you dfkrug!

along with the tilting steering wheel the brake design is less than stellar

I'm thinking of putting something to assist in unsticking them, I have a couple things in mind

I can't agree with that either. They are somewhat complicated from a linkage standpoint but they are effective and highly adjustable. When I finally figured out how it all worked together it only took an hour to get everything back to factory specs.

They are obviously complicated enough that many people just shouldn't touch them. Mine were way off in their adjustment. Someone had spent a lot of time screwing them up. Makes you wonder whether they are too complicated for the average assembly guy at the service shop too as I don't know why you'd ever touch them after they were set at initial delivery.
