Flushing out tractor back end

[Durrus]

Just in the process of doing the brakes on a JD 6600. Oil came out clean, but we found the brake discs were well worn down with a lot of brake material sitting in the sump behind the screen for the transmission.
Just wondering what would be the best way possible to flush this material out?

TIA

When our Claas forager spat out the contents of the charge pump they put it on a dialysis machine when it was mended. Ran for about ten hours with the oil being constantly changed and filtered.

We had a tractor gave bother when new 20 years ago, they nailed it down to the gearbox not being cleaned out properly after drilling, they couldn't get the last of it out so ended up putting in line filters in the pipework by replacing pipes with hoses with the filters in the middle.

Initial flush with diesel
Then do a couple of oil and filter changes, checking contents of filters each time

If it was mine I would like take it for a run on road to get hot and stir everything up then drain

Has this tractor been used for towing heavy trailers on roads where the trailer brakes are not working correctly?
Is oil cooler blocked?
