6080 Touchy Brakes

Have my recently purchased 2wd 6080 in the shop going through it and finding its had a bit of a poor life with some crappy maintenance, and slowly getting some issues sorted out. One problem i haven't figured out, which may not be a problem at all, is the brakes. There is very little travel in either brake pedal, and as soon as you touch them the brakes lock up. No easing or feathering the brakes, its all or nothing. But at the same time the brakes don't seem to be partially engaged or dragging as the tractor rolls freely.

Is this normal for the 6000 series or is there something going on?

Never heard this before. Don't think it's normal. Someone will have your answer.

I’ve experienced this in an 8000 series that also had a poor life

Not a lot of travel on 3 of mine.

I dont have a 6000 series tractor but I recall reading that the brake system on them is seperate from the hydraulic system and is master cylinder and brake piston similar to a light truck. I had a ton truck that had a leaking master cylinder and would get air in the lines and the brakes would grab
Just a shot in the dark

If they run in oil sometimes yellow bucket oil can cause that

How can Yellow bucket oil cause this ?? Explain please = Yellow Bucket 303? Yellow Bucket 334??? Explain that one

Pedals arent rusted together, work independently just fine.

The brakes themselves stop the tractor and don't make any grinding noise like metal on metal, you just can't ease into the brakes. Bit of a pain when pulling a square baler and load of hay down the road, and you have to try to slow down without throwing all the hay off the wagon.

Our 6060 has really good brakes and as said do not require much travel to activate the brakes. They can be feathered or to full stop with little effort. If it has been sitting for awhile it may be that they just need to be used a bit. The system takes a special fluid not BRAKE FLUID. May not be a bad idea to drain the system and refill with the correct fluid. That could be your problem

303 is NOT a hydraulic / wet brake fluid...you'll have more than chattering brakes running that

Anytime I buy a used tractor I always drain all fluids and change them unless there is good documentation showing it was recently replaced with quality and correct lubricants, filters. If you haven’t already done so drain the transmission and differential and replace with 821 fluid. Drain and replace the brake system fluid with SAE 10W-10. The bleeding procedure is on page 65 of the owners manual. If someone put the wrong fluid in the brake system it will not work correctly.
