Thats a lovely display of the internals(scratch) ,looks complicated ,my question is when I bleed the brakes does the fluid just push the piston out to the pads or is there some other kind of adjustment that is required ,if anyone can give me the link to the manual for the brakes that would be great (that piston needs some serious sanding to get the rust of which is caused by not servicing the brakes ,(oil with moisture)Thanks PCB
