Okay to start with, i am going to do a full brake refurb I want to replace the seals in the callipers, is ebay ones http://www.ebay.co.uk/itm/RENAULT-M...omain_3&fits=Model:Megane&hash=item3ce8bf72ce okay to use or should i go to Renault. I already have Orange paint, but might go powder coating your thoughts please. I have stainless brake lines ready to fit, yes in Orange :cool: Ds1.11 ready and waiting Now for the can of worms Grooved discs are supposed to help clear dust and gasses, correct ????? Can i get grooved Brembo HC discs or are they only plain, i would also like them to match on the rear as well if i can get grooved. What is wrong with EBC discs, was thinking dimpled and grooved, as drilled tend to crack or am i talking bo**ks. I have used black diamond in the past on a Fiat Uno Turbo, now you know i am old are they worth a look at ??? This is going to be mainly tracked with some road miles as well. Is there much of a difference between the 312mm and 330mm brakes, i know the price difference, is the performance that much better Sorry for dribbling on
