Advice Needed On Brake Rotors (r33)

Hey all,

Car in question: R33, GTS-T.

Basically about 2 months ago now, I had my car serviced and various things done at a very reputable workshop in Brisbane, one of the things I had done was to have all my brake rotor's surfaces machined. I was advised that I didn't need new pads on the car at all as there was still plenty of 'meat' left on them.

In the last couple of days i've noticed a ring develop on my rear brake rotors, only the rears and both sides, although the rear right seems more prominent. It isn't that there is a gouge in the rotor at all, its all smooth when you run your hand across it, it just looks to be a different colour to the rest of the car.

I took some pictures so you can all see what i'm talking about, I just want any advice if anyone has come across this problem before and what it was? Or if maybe I need new pads? Any advice would be good, thanks in advance.

i would always get new pads with a machine of the rotors, so they bed in to the surface on the rotor..

could be that your rotors had a high spot in that area and the pad isn't touching completely now that the rotors are flat.

it's recommended to change pads when you change rotors, but not totally necessary.

All you do is take out the pads and turn them face down on a flat concrete surface, stand on them and rub them a couple of times. This removes any unevenness cut into the pads by the old rotors.

My rotors have a couple of lines on them like this, I changed pads & rotors at the same time and this has happened.... don't worry about it!

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
