sounds like a warped disc. Did you have the factory brake upgrade option if you have the brembo's or where they added afterwards?

Make sure you clean the hub of any corrosion when replaceing them.

thanks for the replys , just found the drivers side lower arm joint is worn as well , im not 100% its the discs as im geting a faint knocking under braking more so when in a turn , plus the steering wheel does not shake as it should if it was the discs, have a new arm on order and will change this week end will update when done
