Well not quite jamming, but dragging on the disc. I think it's a heat related issue, as they were fine (once I'd recentrered them by looseniung the mounting bolts, squeezing and holding the lever and tightening the bolts). But today when I got the Pino out for a pre ride clean, the rear brake was quite draggy.
I've not had a hydraulic disc braked bike before, so all this is new magic to me. I don't have a bleed kit (yet).
I tried pushing the pads apart with a suitable tool but no joy. I loosened the bleed screw on the lever and did the same. Some movement, so I though all was good, but no, still dragging. Possibly less, it's hard to say. There's no bite point adjust on the levers. The front is OK.
Before I FUBAR it, any suggestions? I'm planning to ride tomorrow in the scorchio heat.
