mechanical brake on front wheel only????

[_paralyzed_]

you still have some diff action, it is a fluid, I burnt up a lot of rear diffs running no fluid, and haven't ruined one since using diff lock lube, and I go through about 5 gallons/2 motors a summer (sorry guys, I run nitro too!)

Depends on how you drive, but for me, front brake only makes a very strange, almost un-driveable, ride. If anything, you want to have rear brakes only, let's you swing that rear end around.
