Porsche Tech Says Carbon Brakes More for Showing Than Slowing

When you specced out that new Porsche you wanted, even if it was just in your head, you picked the carbon ceramic brakes option, right? Of course you did! Track day, bro!

If you want to haul your new 911, Panamera, or Cayenne down from speed on the circuit, you need the carbon brakes. Every chump knows that. Or do they? According to one of Porsche Australia’s top techs, the carbons might actually be for hard parking, not hard lapping.

“Yes, ceramic discs can degrade if you’re hard on the brakes,” Paul Watson, Porsche Australia technical representative told Australia’s Wheels. “Heat build-up will degrade the carbon fibers in the disc, so if you’re doing club days we’d always recommend iron discs.”

We all thought that carbon brakes were designed to last forever. No matter what the use. But Watson says that’s not the case.

“When we first launched the discs we told people they’d last virtually for the life of the car and people were doing a number of track days and coming back to us saying ‘I’ve worn them out’,” he admitted. Though he, of course, wouldn’t say just how long you can expect them to last.

That’s important to know since PCCB brakes cost $8,000 and up to add as an option. Then it can cost well over $10k to replace the rotors alone if they wear out or get damaged.

They do, though, still look cooler, weigh less, and should last longer than iron brakes on the road. Especially if you’re parking for the winter and the brakes see more years pass than miles, which isn’t uncommon for the kind of car that has carbon ceramic brakes.

So who are carbon brakes for? “People who don’t like cleaning their wheels. They don’t leave a build-up of brake dust, so that’s an advantage,” claimed Watson.

Bless Australia and their honesty. Though we’re guessing some execs back in Stuttgart aren’t reading this with as much joy.
