JD 4430 brakes squeeling right above pedals

Reid1650 · Oct 11, 2012

I have a JD 4430 everything works great, even the brakes. After about 30 mins of the tractor running the box where the shafts from the brake pedals goes into starts whining. Anybody have any knowledge on this issue? Thanks

I haven't witnessed this but it's possible that the strainer(parts key #42) has some debris in it or an o-ring is leaking in housing.

I also wonder if noise could be coming from the brake accumulator??

Don't use it have it repaired first before it ruins the brake system. Your brakes use the trans pressure to operate the brakes if the valve goes bad it will keep some pressure on the system and wipe out your brakes
