First of all thanks for the help!
: Well I just found that one of the pads is 2 mm more inwards than it should be and the piston doesn't seem to want to retract. I'll try the wheel seating method, thanks, although I'm now fairly sure it's the above problem. ^
I'll see if I can get the pads out to sand them. Is using 96 degree alcohol an OK substitute to rubbing alcohol when cleaning the rotors?
When I talk about the play it's when I fully lock the wheel, the rotor isn't moving, it's something else and it's starting to worry me a lot.
The Great Stonk
: The fork is an RST Gila T5 (2005) 100mm travel, yes, very crappy but seems to not want to die. The fork has a fair amount of play in it but the amount of play I'm experiencing (if it was in the fork) would make the fork not safe at all to ride. I just tightened the headset today, I'll see if it helps solve the problem.
The rotor bolts are fully tightened and in place.
I'll have to check the spoke tension though, haven't thought about that much. What would you classify as dangerously low?
The CPS bolts are snug when I set it up, I doubt they're the culprits.
I still get 2cm of play even when I'm pulling really really hard on the brakes so again, I don't think it's that.
I'll try and get the pads off without screwing the system up and sand them a bit.
I really appreciate the help, thanks a bunch!
