I was also saying that it sort of looks like the parking brake has it's own set of brake shoes and if these do not press the rear pads against the rear rotor then how does it effect the rear brakes? I'm just looking at the diagram posted so I'm trying to understand how the parking brake works on the M3. I don't see where it connects to the rear calipers, which is what I was expecting to see. |

If you get on your brake pedal to stop the car and sit on the brakes after a session (say you decide to chat with someone on your way before parking and apply the brakes for a few minutes while doing so), then I guess you could warp the rotors since you might be affecting how the rotor cools and contracts. That is what I should have said earlier as opposed to referring to the parking brake. It's still not a good idea to engage your parking brake though.

This is why I never use the hand brake after sessions and I confirm it is a drum-based system independant on rear wheel. I usually leave the car in gear on a flat surface and move it half a wheel after 10-15 minutes to avoid all the heat going only on one side of the discs. Cooling laps are important but not always easy on open sessions with a lot of cars. Also Lucid, as you mentionned, it is incredible that the BMW technician speaks only about wrapped discs and no word about pad's depot. I am now facing 2 opinions about the same problem and I don't want to have trouble with my dealership. |

Yes, I see where keeping your foot on the brakes after a session could explain warped or deposit damaged front rotors. If you had to hold the car still on a hill with the engine running after/during a session do you think it would be better to use the parking brake or the disk brakes? I believe the front rotors get hotter than the rears so I think you would be smarter to use the parking brake than the disk brakes. Stupid idea? |

Oh, I see. I haven't been in such a situation, so don't really know. Maybe use the regular brakes and roll the car very slightly every 15 seconds if you can't stop on a flat section?

Mine has only done 3000 miles or so on it, 2 track days, and the front discs are already cooked! They vibrate really badly on high speed and heavy braking - got it swapped out 2 weeks ago from BMW under warranty( the 2 fronts dics were warped). Need to find something more reliable.
