WTF?!

Ride down a hill with it on then ride up it with it on then put muddy/grimey water on the disc. Then ride it normally. If i was you though when you start to get on corners of railings etc i would get rid of the rear v brake and get a magura bolted down, will be so much better at holding on stuff

I would try changing the plastic washers that go around the slave cylinders, this might just solve your problem.

What you need is one of these beasts http://www.tartybikes.co.uk/product.php?pr...category_id=104 and if your running standard pads you want some of these aswell http://www.tartybikes.co.uk/product.php?pr...p;category_id=4 on a grind that should be good and quieter.
