| Everyone's saying, replace discs as a pair. Why? I wrecked a disc on my bike when it was fairly new, ie, around 10k miles maybe, (just don't ask, right?  ), and I replaced just the one disc. The bike was still under warranty then, and the dealer's never felt the need to say, oh, you'd better replace both discs as a matter of course.Obviously if your "other" disc is on it's last legs anyway, it'd make sense to change them as a pair. but if it's serviceable, I see no reason why the brakes won't work fine with one replaced only. Check the thickness against the minimum value which should be stamped on the carrier. Use a micrometer, though: a vernier gauge will pick up the ridge at the edge. In all honesty, the difference between "min" thickness and "max" (ie, new) thickness is pretty small anyway (0.5mm?), so you'd never have two wildly different discs. Discs aren't cheap after all. I'd stick with Brembos, though.  |
