Now, it has to be a really big smash for your wheel, but, in some cases you can bend your disc brake rotor. This is something that you need to fix ASAP – bent rotors can play havoc with your disc brake pistons and more. There are a couple of fixes for this one. If you still want to use your brake (we'd recommend this route), try bending it back like we show you in the video. Got a tip to add? A mechanical that you need some help with?
