Replacement brakes for G3 ski bindings. If you've broken a brake or are switching skis and need a new width, look for your G3 brakes here. We are currently stocking the ION brakes which work with both the ION 10 and ION 12 bindings. You likely wouldn't get in trouble for putting some brakes on the ION LT 12 binding either. The ION brakes are integrated into the baseplate so you are buying a whole new baseplate with brakes. That means you will need to remount your bindings to install the brakes. Price is per brake, so you will need two (2) for a pair of skis.
