I have been watching from the sidelines on this thread, up until now, but it is obvious that there is no real knowledge of this vehicle and similar types. Most tracked vehicles, being low geared, have reduction units outboard and braking systems are inboard of them, take CVR(T) as a common example, so it is possible to have a brake before the reduction, just needs calculating the size and effort needed.
The other point is that another actual brake is not absolutely neccessary, because hundreds of thousands of road vehicles produced and in use, use the same wheel brakes for main and parking, just different methods of applying. A hydraulic set up on the existing linkages could be made relatively easily. Not a job for the Sat & Sun mechanic, it needs to be made, tested and approved before putting in production and installing. And no, I am not looking for work here, just applying long term experience on "weird and wonderful vehicles".
Going back to sleep now :yawn:
