My dad gave me his Scalpel 29 4 2013 and I've been working to get it to a good riding state since it sat unused for a long time and the challenge I'm struggling with is disc brakes rubbing.
I learned to gravity bleed the brakes, and in the process I cleaned the bike, the calipers and equipped it with new shimano disc rotors and pads (my dad had uberbike ones, they were a little rusted and I wanted to eliminate them as a possible issue).
After getting the bike back together I used the whole loosen, hold brake, tighten bolt method for the rear, it didn't seem to work, I sometimes wonder if that method ever works. But after eyeballing it and adjusting it myself, to my shock I got it to spin perfectly with no rub.
But the front caliper resists my every attempt to center it. The wheel is a thru axle, not a drop out, and there's no play in it, I even bled the brake further to make sure the lever was as responsive as it could be. I tried a hayes alignment tool, I checked I had the right mount. No matter what I do I can't seem to get the wheel to spin freely without the disc rubbing. The amount of space I have to play with seems incredibly small, and the caliper mount even comes close to pressing into the rotor if I push it too far right.
My dad says he never got it to stop rubbing either, and I know he replaced the fork on this bike. But I don't know what to try next. Here are some photos, I don't know if they're any help.
