Brake discs Raybestos or OEM Volkswagen

FWIW, I recently replaced my front rotors and pads at 40k and I have about 8mm on the back. At this rate, I'll probably have to replace the backs around the same time I do the fronts again. My rotors look nothing like yours though. Mine are smooth and no grooves.

I had the impression that those discs wouldn’t warp as easy as one piece discs but it looks as I was wrong. VW tried to machine my warped discs with them mounted on the car at one point but they failed so badly that they did not even want to show me the result. After that they messured the runout on new discs on the bench and found them OK. After the discs were mounted on the hubs they were messured again and that one of them had warped. That was the way they found the bad hub. I was quite surprised when I was told that VW did not have any tolerances for the runout on the hubs or the discs. I took for granted that they had quite strict tolerances both on the hubs and the discs. I don’t know if the eight piston caliper and the setup with opposed pistons makes the whole system more sensitive to warpage or not but that has been suggested. And to get this a bit more connected to the thread subject I can add that I have not found any alternative to VW original 365 mm floating discs at all. I was quite surprised to find them cheaper than the one piece 334 mm discs to my Passat W8 though.

Could be the hubs. Mine had an axial throw of 0,02-0,03 mm which I thought wouldn’t affect the discs. I filed a complainment to VW regarding warped discs and they blamed the calipers. Told me one of eight pistons was a bit sluggish. With new calipers and two sets of discs later they found what I had meassured before the complainment, a warped hub. The last pair have not warped after the typical 5000 km mark as before. So at least the floating 365 mm discs are very sensitive regarding straight hubs.

Just the bigger carrier with the bigger rotors on the front. Didn't bother with bigger for the rears. I bought Red Stuff pads.

On my truck I got a screaming deal on some Brembo pads, and Raybestos rotors. Put them on today and I swear the truck stops better than my Impreza ever did with the Advance Autoparts Wearever Gold that were on it.

That being said, it would be great to see a basic writeup with pics of the fronts and rears being changed. I ordered and received some new slotted/drilled rotors with ceramic pads. When ordering, I just used the GTI as the model, since it uses the same brake rotors as the TDI, 312mm F, 272mm R - IIRC. If I have time, I will get some pics and write a rudimentary writeup on it. Not sure if I have time/patience to tackle this myself so I may just have my Audi/VW guy do the work (he has many more tools and 2 lifts). In any case, I will try to get some info and pics in here.

Just discussed this last week. I side with my VW dealer on it. They recommend just replacing the rotors, its really not that much more than having them turned, considering you almost guarantee no pulsation, no shimmy or shudder and more even brake wear.

I am happy with the R32 setup so far ( rotors are freaking heavy); but if I was to upgrade it would be either AP or stoptech trophies....

I looked at the brakes on our Tiguan, and it has one disc that is notably scored, same way. We just crossed 2k miles.

The rear brakes will be an absolute nightmare. There is not a lot of room. As far as I am aware, MK6/MKV R/R32 brakes are the same, so... prepare yourself for a miserable time doing the rear rotors. The rear pads are fine. The rotors suck ass.
