It is very common for the brembo supplied duscs to fail by warping, mine went after 4k miles, got skimmed, went again after another 3k. Waste of time, crap material, how else can they do massive discs and 4pots for £800 fitted!?
I am trying the EBC ultramax discs at the mo with ferrodo pads and this set up has an excellent feel and bite, the pads are not anhaialating the discs yet , either.
If you want "warp free" (as far as you can get warp free), get Stock Seat Leon cupra undrilled discs and run them. They are expensive though, but high quality material.
One thing you can try with your existing discs is to heat cycle them and see if they true up. Go out when its is quiet and do several accelerations and heavy stops one after other until you pretty much have ****** the brakes and have very much reduced braking or brake fade (be careful dont crash or get nicked!) Once they are really ****** up, drive the car, do it on a bypass or dual carriageway roads where you dont need to brake and drive the car steadily for about 30 mins, not using the brakes at all. This is important as it allows the brake discs to cool while rotating and does not allow heat spots to occur. For eg, if you got them very hot and then parked up, the material of the disc would cool more rapidly on the bit of the disc you can see and less so "under" the caliper and brake pads. This is often why they warp and compunded if it is raining or very cold.
Put a serious heat cycle through them and they may true up, they may not. But remember to drive for at least 30 mins without using them then very gentle braking only until you get home, next morning, see what they are like.
If you do go for new discs, do your self a favour and heat cycle them after and initial very gentle bedding in process (a few miles only) as I decribed, but it is real important to do it where safe and quiet, to get best results. I do mine at 3am on the dual carirageway then, hit the motorway and cruise for an hour.
Good luck, oh, btw it's "brakes!" not "breaks!" !!!lol
There is a lot of nonsense talked about brake bedding in, see how racers do it! They ragg them up to temp, driver a slow cool down lap and are ready to go!
