M4 GTS Brake 'rings'

Steve Gill · 06-07-2021, 09:18 AM

Anyone has seen this before? I'm wondering if the pads aren't sitting correctly? They were starting to make a squealing noise.

Not uncommon, often times you will see race cars with front brakes glowing under heavy breaking, usually the whole rotor glows, you look like you have hot spots or perhaps they are hot but not hot enough to have them turn red uniformly. Just my thoughts, I suspect the pic was taken at a track event.

Yes, not that uncommon. You can see from the photos attached from my night outing at Sebring that the rotors are normal and dependent on the brake pressure do show the same pattern.

Thanks - yes, was at a trackday in Scotland. You can see a slightly more uniform pattern in this picture:
