Carbon ceramic brakes on S65 coupe questions
Hi guys,
I'm considering buying a 2015 S65 coupe with 40k miles. Since I can get an extended warranty I'm not concerned about too much but there's one thing that worries me, probably out of ignorance.
The car has carbon ceramic brakes and it was confirmed by the dealer that they were not replaced and the report says they meet, at least, the following criteria:
- brake pads/shoes/hardware (shoes 2/32" min. thickness; pads 4/32" min. thickness; free of cracks, excessive tapering; clean and lubricated)
- brake rotors/drums (meets OEM min. thickness/max. diameter; no excessive vibration, free of excessive rust, grooves, pits, hot spots)
I think pads are like $4k and rotors like $20k and I'm assuming the previous owner sold it before the pads were worn, like it usually happens. Can you guesstimate how much life both have assuming it was not abused?
I'm not really sure what's the average lifespan of pads and rotors of this kind but I seem to remember it's much more that regular ones, again, assuming not being abused.
Any info will be greatly appreciated.
Thanks,
Leo

Most likely I would keep this car for many years, assuming CCB rotors last 100k miles, can they be changed easily to conventional brakes afterwards? I understand that adds weight but I don't intend to track this car at all, to me this is luxurious GT that can go very fast.

I was told by a dealer rotors last at least 50k. I would make the dealer give spec of pads and rotors. Not say they are ok. Of course they are ok today, what about next month, Then the are bad and you need a brake job.

the dealer says that at least complies with those standards, but I don't know if that translates to 60% or 20%...

I called the closest dealership here in Central Florida and I was told that for these cars the pads and rotors should last one or two years tops and that's a really bad idea to downgrade to conventional brakes. I found a post from several years ago where a guy was told the exact same thing but in reality it was very different, it seems the dealerships didn't change their speech...

thats wrong, who knows how many miles you drive in 2 yrs? thats BS
You need to get the spec, see what the thicknesses are then compare to new, and the mileage.
Nobody here can see your car and measure the parts and give advice.
You have to do the work yourself or you are just mister consumer, blindly doing/trusting what ever the sales/service man tells you.
