I took my wheel off my front forks to repair a puncture. I had the bike upside down when I removed the wheel. When I came to replace the wheel back into the fork slots, the hydraulic disk calipers were too tight to accept the brake disc. I had to use something to prize open the calipers so the gap was wide enough. When I span the wheel it's still to tight and the calipers still make contact with the disc. Is there any reason why the calipers are now tighter and how do I fix the problem?
Thanks.
