Yes, the Deere 410 has internal brakes. They're inboard of where the axle housings bolt to the main case. If you're getting a chattering or grinding noise when you apply the brake it's almost certain that the lining is worn away, you have metal on metal doing the braking. There are other possibilities but brake lining is the most likely. This machine as I said before has common oil for all drive and hydraulic functions so if the brakes are grinding up metal it will get in everything, transmission, diferential, steering, loader, backhoe, pumps. Change the two transmission/hydraulic filters, look for shiny silver material in the filters.
