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

[@stephensheppard3501]

@420 Friendly they are more concerned with selling new cars than worrying about repair of used cars, they also would not be paying that price for the repair anyways.

[@subscribeowikd3336]

[@gwot]

@420 Friendly I wasn't in sales, reasons unknown to me, we check the cars for maintenance stuff after buying them, the used car dept pays for brakes/tires all the time.

[@gwot]

@@stephensheppard3501 we do pay close to that actually, the mechanics still get paid the same amount, and our cost was only like 2k less than retail

[@dbclass4075]

Due to that, some owners swap the pads to steel and then reinstall the original pads when it is time to sell the vehicle.

[@Balomis]

"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

[@fuzzy1dk]

makes no sense that 70% would be from the rotors, the data showed was 1500x the wear on pads vs. rotors on thickness, the rotors are no where near 1500x the area of the pads

[@truantray]

Porsche says that. But his own data says pads wear 1500x greater than rotors, and dust comes from pads. Anyone knows dust difference between organic and semi metallic pads is huge. Also Porsche owners rarely buy their cars, they rent them, so they don't care about resale or any wear beyond 36-48 months.

[@CED99]

Yes, if the pads wear 1500x the speed of the rotor, that's 1500 good reasons to expect the brake dust to be mainly pad

[@Balomis]

@@truantray I think y'all misunderstood EE, that "1500x" metric is specifically about the tungsten carbide rotors and the pads designed for them. Typical rotors are cast iron and the pads eat away at them significantly faster. Metallic pads actually produce more dust because they remove more material from the rotors, which is a byproduct of the increased braking performance.

I guess some people here have never worked on a car. You made me laugh. As a mechanical engineer I have wanted to throttle the person that designed some of the junk on cars. I mean really, why is the fuel tank access port on top, where you have to drop the tank to get in it. I am pretty sure we have the ability to seal one placed on the side or bottom where it would take seconds to access. Or perhaps having to remove the exhuast system to replace an O2 sensor. Or remove the entire engine to replace an alternator, distributor, or AC compressor. The list goes on...

[@SteinOnkel]

@@court2379 The access port for the fuel tank is on the top, so that you can access it regardless of how much fuel is in it. O2 Sensors mounted vertically can get too hot and if they are mounted from the bottom, condensation can collect inside of them, causing misreadings and failures.

[@dagandrefjeldstad3856]

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.

Not unless you’re racing... For street use the racing type are worse (like ceramic won’t work well until it’s hot, and bare metallic pads are really loud screeching and destroy rotors fast), so the best ones for regular street driving are the normal semi-metallic and maybe even some organic ones (but the organic ones are often worse).

I recently drove an EV owned by a relative who almost never touches the brake pedal (he uses strong regenerative braking and tries to drive "one pedal" almost entirely), and even though the car is driven daily the rotors were clearly rusty - I could feel the grinding when I used the brake pedal.

Nice to see Porsche have their calipers in the right place - inboard! (Front ones on the rearward part of the disc, rear ones on the forward part of the disc). This reduces the cars polar moment of inertia; calipers are heavy un-sprung weight so ideally should be as close to cars C of G as possible. All cars where handling is a feature, from the MX5 to a Ferrari, will have inboard-mounted calipers. Sometimes they paint them red or yellow to illustrate this plus point. However, on many cars with no pretence to great handling the calipers may be mounted anywhere around the disk - and that's OK. It is a marginal advantage after all. But what gets my goat are manufacturers who put the calipers in exactly the worst position - outboard - AND THEN PAINT THEM A BRIGHT COLOUR! It's as if they think it's the bright colour that gives the handling advantage! It's like saying "we put the calipers in a poor place for handling, and then we painted them bright yellow just to show how we got this wrong"!

[@NavarroOne]

When you mentioned the Mohs scale, it would be nice if you included the hardness of cast iron rotors

[@hlund73]

Probably not an appropriate scale. In reality this will be a much more complex engineering problem - even the fancy brakes are mostly iron. For a simple comparison about 4-5 mohs

[@kilpatds]

From my experience tracking cheaper cars with iron rotors: rotors wore out after about 4 sets of pads. A friend of mine who has way more experience tracking cars has been tracking his car with carbon ceramic brakes for the last 5 years or so, and has yet to need to replace a rotor. The cost comparison needs to be for N-sets of pads (per the manufacturer's estimate) plus one set of rotors for a total cost per M miles, and then turned into a cost-per-mile estimate.... otherwise you're comparing "things that will happen to you" with "things that won't happen to you" and wondering why the costs differ.

[@Jaqen-HGhar]

lol at replacing rotors

[@Francis-rs7zu]

@Wypipo Trippin Not everything is about having the cheapest brakes per mile driven. Performance comes at a cost. I had regular cast iron brakes on one Porsche, and they lasted about 25K miles before wearing too thin. OEM Parts cost about $1700 for a complete brake job.. My next Porsche was a GT3 with carbon ceramic brakes - a $10,000 option. Predicted lifespan of the rotors is over 250,000 miles. I replaced only the pads at 75,000 miles, and they had about 60% life left. The rotors were still good for another 200K miles according to the dealer. This was after multiple high speed track days. In the long run - the ceramic were cheaper. THey also weighed about 44 pounds less which mean increased accelerating and braking. I could brake 60-0 less than 2 seconds, less than 98 feet.

[@kilpatds]

@Wypipo Trippin when you track cars, the brakes wear out a LOT faster. :) One track day took out about 1/2rd of a set of pads. Per the above estimate, 8 took out rotors. This is on a Corvette that otherwise would have gone over 50k miles on a single set of pads easily. Per my friends experience with carbon ceramics, ~20 track days had done nothing evident to the rotors. So that "million miles" equivalent comes up a heck of a lot faster in tracked cars than you'd think. :)

I doubt they invented it. I believe their ceramic brakes are by Brembo. You can find OEM ceramic rotors but they are still expensive. There will no doubt be lower cost OEM options for the 3 people who own a cayenne but care about saving money.

[@cknerr]

That is an old machine shop technique called spray welding. Spray welding is often used to build up a shaft's OD after it has been damaged or machined a tiny amount too small (usually called an oops). The bearings on the end of a shaft has some tight tolerances, so this technique builds up a ceramic layer that can then be machine down to correct size. I am thinking Porsche figured out how to get a hot enough flame to melt carbide or did they simply melt a ceramic with a high percentage of carbide? There is a huge variety of ceramics that could be used. Usually they are brittle, so I wonder how they got around that issue. BTW, I am an engineer too.
