On my JD A the left brake grabs when I use it and makes a grinding noise and almost kills the engine. However, sometimes it works fine, especially if I push on the pedal fast. The right brake works fine.

Broken lining stacking up?

Randy K. Crump · Feb 21, 2014

When you say "broken lining stacking up", do you mean the brake shoe lining is coming off inside the drum?

Mike(NEOhio) · Feb 21, 2014

Mine used to make the same grinding sometimes but it wasn't the brake. It sounded more like gears. I recall seeing a post here some time ago about adjusting the shifter rod for 1st gear (I think) to align the gears. That pair of gears is outside the main case under the cover just in front of the flywheel cover. It doesn't seem to do it any more so I never really got into it.

Yes that"s what he means. It"s either that or
something else has cam apart inside the drum. You
will not know till you remove the drum?

Any accumulation of old oil saturated INTO the lining material will cause the brake to GRAB real BAD...bad enough to break things.

To remedy that cause, take the lining off, place in a shallow pan (out in the driveway), pour a 1/2" of gas in the pan and lite it up and let it Burn..

When cool, put them back on..will not hurt them one bit but will burn the saturated oil out of them.

Yep. The brake not wanting to release makes me think that a broken piece of lining is getting wedged between the drum and another piece of lining that is still attached to the shoe. Basically causing a condition where the brake lining instantly becomes twice as thick as it should be. A broken lining could leave a bare spot on the shoe or an exposed rivet that could cause a grinding noise. Does it unstuck when you pit it in reverse?

Pull it apart and find out

Mine was usually oil saturated. when you pull out brake assembly check the oil return hole in the bottom of the 3-1/2 hole where the brake assembly goes in. Stick a wire down it to make sure its clean

Drum units are so easy to remove why not just pull it and check for sure.

Randy K. Crump · Feb 22, 2014

I don't need to put it in reverse to get it unstuck. All I do is pull the clutch in to stop the tractor then push the clutch out to begin moving again.

The support arm for the loader is very close to the drum. I don't know if the drum will clear the loader and I would rather not remove the loader.

You don't want to put off checking out a problem with your brakes. Being able to stop when you want to is far more important than being able to move forward when you want to. My dad told me about when he almost put my grandpas "G" into a ditch because a broken lining stacked up on him while he was motoring down the road in high gear.
