Ceramic brakes and the effect on crawl/traction control

I need to get some new brakes. I am an OEM-ist, provided cost isnít insane. Akebono comes with a whole lot of high praise and so do the OEMís. Cost is the same (Since local dealer didnít want to price match online and shipping made it null) and brake dust & noise have not been an issue.

Also there are 2 different part #s for the oem, one one the car at purchase and the one installed if they do maintenance? Why? Are they accounting for test drives?!!

My inference is that oem is semi-metallic & Akebono ACT is ceramic (correct me if Iím wrong about oem). Through my research the pros and cons of each are there & itís a toss up with trade offs either way.

So I was going to go with Akebonos, but I had a thought and canít find any info on how the change in material affects the traction/crawl control. Does it screw with the programs that control those systems? Do they adapt?

Google ainít been my friend. Anybody have some thoughts or directions toward informative material?

Metallic pads tend to have the best grip and provide the most grip without having to be warmed up. But most street ceramic pads have similar grip and warm up quickly, so that's not much of an issue. In a way, given how the crawl/traction controls work, the ceramic pads might be better on the rotors, last longer and resist heat fade longer with the constant brake pulsing.

As for the traction/crawl systems, they are only detecting wheel spinning and traction loss. So if a grippier steel pad stops the wheel from turning and it begins to slide, the ABS system will release the brake to restore traction. On the less grippy ceramic pad, all things being equal, the wheel will may continue to turn without engaging the system, at least until a bit more pedal pressure is applied and causes wheel lock up. Regardless, you get the same result. In a stop situation, slightly more brake pressure would be required for the ceramic pad before engaging ABS.

From a stop or on slick surface, the traction control/LSD senses the spin and applies as much brake force as necessary to stop it and send power to the wheel with traction. This is done without driver input and the system would not care what the pad type is.

I would go with the Akebonos. I've ran their ceramic pads on multiple vehicles and they work well. Less brake dust too.

Thank you for filling in the gaps on that. I was thinking that way but wasnít really sure if they physical interface would screw with the electronic. Thanks Boss!
