Question:

What do Ceramic Brake Discs Actually do on a Porsche (exept be bright Yellow)?

My dads currently got a Audi RS4 but is thinking of getting a new Porsche 997 911 Turbo.He was running through the option list and he, nor I, knew what the Ceramic Brake Discs.They are a ?5,000/?6,00 option and wasnt going to fork out that sort of money untill he really knew what they are. There supposed to be Fade Free Is this True? If anyone knows anything about them in great detail please write backP.S He has spoken to a Dealer about them

Answer:

Carbon ceramic brakes do have a number of advantages. First is weight. Theyre about half the weight of steel rotors, which is a huge difference in both unsprung and rotating mass. They also are fade free. That being said, In my 996 GT2 with hoosiers (racing tires), I recently switched to steel rotors (the PCCB ones were dieing on me, and theyre hideously expensive), and I have yet to get any fade. The fade issue would only come into play in rather long races with very hard braking. They also do wear extremely well, but the cost of running them is still far more than steel brakes. instead of an 8 thousand dollar set of ceramic rotors, I bought some performance friction (awesome brakes) rotors for about 350 bucks a piece. The last upside to the ceramics is the awesomely linear pedal feel. In hard braking its just totally linear stopping power. Steel rotors you usually have to do a hard initial stomp to generate more heat, then slowly let off a bit to get maximum braking. If youre not doing significant track use, dont even bother with them. If you are, Im still not sure I would. Theyre awesome, just not 8 grand a set awesome. And tell him to consider a 996 GT2. Much more raw/awesome car. its like the turbo's twisted, insane cousin.
Yes. If the house is built on a slab the water pipes are put in place and covered up before the slab is poured. The pipes are brought up in appropriate places to feed the bath rooms, kitchen, etc. My house is on a slab and after 35 years I started developing leaks in some of the piping and I had to reroute the pipes through the attic. The pipes today may be of more durable material which hopefully is used to give them more longevity. But I would suspect a contractor might go the cheapest rout to save construction cost if it is legal

IF you can find a tempurature laser gun shoot it on your bathroom floor and that will show you where the hottest spot on the concrete will be, then you will more than likely have to bust that concrete area to repair the leak. The copper lines run under the slab and then only go through where they are needed to supply any fixture. Water does travel the path of lest resistence and could show itself many feet away from actual leak, but it being hot water, the temperature gun should pinpoint the closest spot being that water will cool off pretty quick.
