Fitted some new discs (Brembo plain) to the front having had judder through the brakes for some time. Only happened when braking from high speed, so had left it for a while. I suspected "warped discs" (or maybe just pad deposits) so finally put some new discs on.
Have CL RC5+ pads, they stop the car fine and the judder seems to have gone now the new discs are on, but the brakes are very noisy. Is this just the pads I'm using? They were never like this when the pads were new. There's still plenty of life left in the pads too.
(Sorry, I can't edit my spelling of noisy in the title )
