Cool Tools series, part 4

Disc brake facing tools – for both post mount and IS mount brakes.

Disc brakes require precise alignment, perpendicular to the hub axle, in order to operate correctly and without drag. Most of the time, manufacturers get this right, but occasionally frames and forks deform or are otherwise made not quite right. That’s where these tools come in – the Park Disc mount alignment tools are very precise and will face material off the brake mounting surface in order to bring them back into alignment. Not cheap – but when you need  them, you need them.
