Thanks for yr help with this mate.
If Im honest, I probably need to spend more time trying to do it properly that just tightening front and back and using the fingers crossed approach - like I used to when I was 14 lol.
I'm in the process of fine tuning a ProX that I got before I stopped building and want to get it spot on, so your help is much appreciated.
I'm sedning brakes away to get them anodised and when they come back, I'm going to put yr method into practice,so again thanks and really appreciate yr help.
