Hi all and happy holidays! Well I figure this year I try to find out why my trigger brakes don't work anymore. Even when it was new (2003) one side worked better than the other, but last year they finially stopped working all together. I looked for adjustment (like on a bike's hand brake) and there is none. They squeeze and feel like they work but nothing happens when you apply them. It says in the manual that then applied (squeezed) it disengages the drive wheel on that side of the snow thrower and allows it to turn in that direction. So by saying I starting to think that the clutch isn't slipping when applied.... is this something has to be taken apart and cleaned or should parts be replaced? Any suggestions.... thanks again for you'r time.
