Porsche Reinvents The Brake Rotor - No Rust, Low Dust, No Fade!

I'm an 11 on Mohs hardness scale after you pull out the whiteboard

Thumbs up for "Engineers don't have feelings, so no feelings were hurt" XD

Loved the "They didn't realize engineers don't have feelings" line. I once took a psych class titled "Introduction to Personality." The professor was getting frustrated because this particular class was very quiet and not really responsive. From the front of the class he said, "Come on! Let your personalities show!" I slowly raised my hand and glanced around nervously, but.. when he called on me I said, "We're engineers, sir. We're here to learn what personality is."

Now I know why people with Porsche never brake in traffic, it is too expensive.

“Engineers have no feelings, so no feelings were hurt.” Truest statement ever uttered!!!

When I worked at a Jaguar dealer, we had a customer that tracks his F-type, for fun not competitively. He changed his pads and rotors 3 times due to wearing them down on track in just a few years... they were carbon ceramic brakes, and surprisingly they're the same price as Porsche's! he basically paid for the car again, but this time just in brakes. I think it would be cheaper to take a hit on depreciation and just trade in the car for a new one than to replace carbon ceramic brakes

“Engineers don’t have feelings” I've been telling people this for YEARS, "I'm not broken, I'm an Engineer."

Jason will develop the first white board brakes. They will cost $20.00 and outperform carbon ceramics.

This technology was used on bicycle rims for many years by a company called Rigida (renamed to Ryde). Their rims were called CSS (Cardbide SuperSonic - indicating the processes by which the tungsten carbide was applied to the aluminium rims. The wear rate was very low and the rims lasted much longer than normal aluminium rims. They did however suffer from brake squeal and somewhat inconsistent wet weather performance.

"70% of brake dust actually comes from the rotors" I never would've guess that, I always assumed it was just the pads! Also, the best part about those price breakdowns, it that in 20 years when the Cayenne Turbo is worth like $10000 on the used market, the brakes will still cost $11000 to replace with OEM parts

Reaching 100.000km on my 2018 Porsche Cayenne S equipped with those PCBS brakes from factory and they still look like new (even with a lot of towing 2.2 tons). Disks look like new, brake pads are at approx 50%. I really like this technology

Lotus used Metal Matrix Composite (MMX) material for the brake disks on the 96' Elise. Mixing silica carbide into the aluminum gave the same hard surface. No wear, no dust, and excellent braking performance. The pad material attached itself to the rotor surface (a few micrometer thick), giving maximum adhesion friction, which you get if you have the same material on both surfaces. Material is constantly transferred between the disk and the pad back and forth during braking, resulting in the low wear of both pad and disk. The weight was as for aluminum, so very light compared to cast iron, reducing un-sprung mass. Aluminum conducts heat much better than cast iron and transfer the heat from the disk to the larger wheel mass and area. So temperature was about half of that for cast iron disks. Downsides were high production cost, and eventually metal fatigue issues from uneven thermal expansion of the different thickness of the boss and rotor when using such a hard and brittle material. Surface coating seems cheaper and better, except for the much higher mass of the brake disk with cast iron as base.

“I’ll put a white board anywhere” : absolute madlad

“Engineers don’t have feelings” They lost them in college getting their degree

I've seen other famous YouTubers who've let their family members raise a truck on just a jack and then their nephew is sitting under the rear suspension, working on it. If that jack fails, his legs would be crushed and his whole life would change. But they're also cavalier about safety in other respects as well, such as not wearing eye protection while grinding or drilling, not wearing seatbelts while driving on the open road, etc. You did just fine suspending the car for a photo shoot, and until you pointed out the hidden jack stand under the floor jack, I hadn't noticed it and I still wasn't concerned. And since you don't have feelings, then a sarcastic response to the haters out there shouldn't affect them, either. But nope, you kept it all above board and showed who's the bigger person. Kudos!

Those brakes cost more than all of the cars I've owned combined
