My rsv 06 factory brembo front discs are loose- the outer section moves when i apply force to them using my hand. I guess this isn't normal and they are coming to an end?- only done 7k of road use. The diameter of them are fine so can these be repaired or is it replace? Im doing track riding from now on so any suggestions on powerful disc and pad combo whould be helpful and were to buy, price etc.
