parking brake on 773 not working?

[linderlawn]

My parking brake recently stopped working. The machine will still move with parking brake engaged. It doesnt seem to affect anything else at this time. Is it just the switch? And could it eventually stop the machine when I am actually using it?

Does the parking brake hold when you raise the seatbar? If not then there must be something wrong with the mechanical parts in/under the solenoid on the middle chaincase cover.
