Hi all daft question but just been playing around on my 2012 evo and when spin back wheel around on lift up stand can just hear slight squeal from disk when brake not on, what is best thing to do do i need more play in leaver?? if so do you adjust the pin on back of brake so that it goes into the back brake leaver more or wind it out so goes into the master cylinder more? only just makes a noise but whats best to do ??

Likely nothing wrong with it as disc brakes do that sort of thing because the pads are mostly allways still in contact with the rotor.

As long as the wheel spins freely otherwise, leave it!

Disc brakes need to be zero clearance, sometimes a little dust will do that but I wouldn't pay it much mind unless there is a big chunk of gravel stuck in it, the pads have a sharp edge which tends to make them self cleaning

thanks people its only a slight noise so will see how it goes

Yeah. Get some miles on it.
