M Sport brakes - all you need to know
This is a great article that covers pretty much everything you might ask in regards to the M Sport brakes.

Turns out I changed my rotors and pads last weekend. I also discovered this bit of beauty...

Interesting quote in this article about the color change of the caliper paint as it relates to cooldown. BTW, I assume they are talking Celsius.
"It is very important for the material in the brake components to have time to cool down in an air stream. If you park your car while temperatures of 500 degrees are still prevailing on the brake discs, the considerable heat will be transferred throughout the entire brake system. And the brake pads too will absorb energy from the hot brake discs. The heat transfer progresses through the back plate and damping plates of standard pads into the brake callipers. In addition to the damping layer of the damping plates, the piston seals and dust shields can also be damaged, as can the surface coating of the brake callipers. Leaving brakes to cool in a stationary position is extremely unfavourable when brake discs are at a temperature of up to 500 degrees. By performing a cooling-down lap, the brake temperature generally falls to below 200 degrees.:

I can tell you from experience the issue isn’t cooldown, it’s the brakes are inadequate for seasoned drivers and they get too hot.
I was routinely doing a cool down lap and continuing cool down by driving out of the paddock to sideroads to get temps down. My calipers still got torched. I think it’s all down to pad size. If the pads had more surface area, temps wouldn’t get as high. |

This is all very true, cool down time is very important. You never want to just "stop" with hot rotors. As in hot during or right after a session on the track. If there is a red flag on the track, you need to pull over and stop ASAP, or course. That is bad! The calipers will turn almost complete black in extreme cases. |

I agree on brakes for the track driver. BWM should have offer the M Carbon Ceramic brakes as an option. I would have tempted myself. Last edited by M2joey; 03-06-2018 at 07:21 PM.. |
