Nissan Titan Carbon-Ceramic Brakes

Hmmmmmm......could be.

It seems that a German manufacturer SGL Carbon AG, along with Audi, are trying to do just that. If they can get the process perfected, they are expecting the price per disc to drop all the way down to $465 a disc. This may sound steep to you but remember that carbon-ceramic brake discs last four times longer than conventional steel discs and go for anywhere between $665 to $2,660 a disc right now.

Here's the link to the article. http://www.autoweek.com/apps/pbcs.dl...&rssfeed=rss01

And here's the SGL website and the info on these brakes. http://www.sglcarbon.com/sgl_t/brakedisc/index.html

Carbon-Ceramic brake performance is revolutionary. The ceramic brake disc achieves not only very high, but also consistent frictional coefficients, maintaining them independent from temperature and weather conditions.

Carbon-Ceramic brake discs offer a tremendous weight advantage (about 65%) over traditional grey-cast iron components. This reduces the weight of the suspension and means a reduction in unsprung masses with a further improvement of shock absorber response and behavior.

Carbon-Ceramic brake discs are designed to last the entire lifetime of a car. Thanks to the non-iron based surface, corrosion is totally avoided, increasing the life span of the brake disc.

Cool. The best part is that in high moisture/humidity areas, the disk won't pick up the overnight surface rust. Wonder if they resist warping better than the steel version?

good question coot! it be pointless to get those if you're having to frequently get them re-lathed.

Here's a quote from the attachement I uploaded from http://www.outlawdiscbrakes.com/ . The attachement is everything you ever wanted to know about brakes but were to stupid to even know to ask...........or something like that. HAHAHA (Author unknown)

Carbon Carbon Rotors:
Carbon fiber rotors (carbon rotors) are by far the most technologically sophisticated rotors currently available. Carbon carbon fiber is a composite material made of carbon fibers in a carbon matrix. It is extremely light, has a very high coefficient of friction (cf = .5 to .8) and can withstand incredibly high temperatures without warping or cracking. The main appeal of carbon fiber rotors is the weight factor. They are approximately half the unsprung rotating weight of iron rotors and are used successfully in NHRA drag racing, Late Model Oval Track and some forms of Road Racing.

On the down side, carbon fiber rotors tend to increase fluid boiling problems in the caliper, which necessitates the use of heat shielded calipers, and the cost is prohibitive for most racers although prices continue to drop as volume increases.

The brake pads in a carbon fiber system are required to be constructed from the same materials as the rotor itself. Any attempt to operate a conventional semi-metallic brake pad with carbon rotor will turn the carbon rotor to dust in a matter of seconds.

So the answer is they don't warp.

Hmmmmm. I've been in the plant that made that type of brake for fighter aircraft. I knew about the dissimilar materials aspects of the stuff, but wasn't sure about warpage or any conditions relating to chemical splashing. (Like thecr@p that is on all of the highways).......

I wonder how much these brakes with the reduced weight would help the times of all the racers we have here?

I'm pretty sure that Mercedes-Benz has been using or at least offering these brakes for quite some time. Anyone know for sure one way or the other?
