Everything was all hunky dory for 6 months after swapping callipers… now what?
Started as a slight rub of the disc on drive side down stroke, I ignored it. Then it got a bit worse.
Assumed I’d bent the disc, but first inspection cleared that notion. I did noticed the cone nuts had loosened a bit - so removed, tightened, headed back out - problem was much much worse.
Had a proper look last night trying to reposition brake, then noticed wear on the calliper itself where the disc was catching. Fiddled with the bold holding the adapted idly while mulling options and the bolt caught on the disc. Took Brake out and voila - disc is actually catching on the mount.
No crashes, no cracks in the frame that I can see through the paint… what on earth has happened here? And… what next? I’m well out of ideas and we are heading towards mud guard season!
