^ not very true theres alot of bindings now such as the sal z12 that uses a screw that you need to pull the toe off first before you can get at it and some heels where you have to take the brake off to get at a fifth screw (sth's)
alright take brakes off four screws on the heel and thats it front two screws on the toe then pull the toe back towards the tail of the ski and youll see the third toe screw
