PSCB Service Life and Replacement Cost

It's 1500 for pads usually.

Unless they are quoting you rotors also, they are scamming you.

And why would they replace your rotors? They are not supposed to rust.
And they are supposed to have way longer life than steal ones.
So can they prove that they are used and no longer adequate? As taycan uses mostly regen when you press the brake pedal

Wasn't it someone here that said, according to Porsche, the PSCB rotors are to be replaced at 6 years, mileage not withstanding. If true, that could be what the SA was warning against.

The Taycan maintenance requirements call for replacement of brake pads at 6 years due to "corrosion" likely from lack of use.

Anyone know if this applies to PCCB brakes, too? - I might need to remortgage the house ?

The Taycan maintenance requirements call for replacement of brake pads at 6 years due to "corrosion" likely from lack of use.

brake pads are 1500$

brake rotors are 6000$

different parts

brake rotors, PSCB, should last 200.000-300.000 km use. Absolutely no reason to replace at 6 years

If they don't last that long, i would argue with Porsche they show you whats wrong with them and ask for warranty replacement if they can't. And if they say the rotor rusted, i would link them the unvailing of PCSB by porsche, where they state black on white: "they don't rust" and again, ask for warranty replacement

PCCB pads should be replaced when they reach 40-50% use, so they damage less the very expensive pccb rotor

PCCB rotors should last again, 200-300k km, basically the whole life of the car, unless tracked a lot; and realistically even more due to regen breaking

Porsche has a tool to mesure PCCB rotor wear.

For PCCB, you can also buy from Brembo, replacement which is slightly cheaper.

Rotors and pads are replaced in pairs of 2; so both sides of the car at once, even if just one is more used.

As a resident of the Arizona desert being in the valley of the sun, corrosion of my pads is about as likely to happen as a 7.0 quake. I mentioned that issue with my service advisor early on and he said that is what wear indicators are for. I'm sure he will have a different slant on things when the parts department is through with him. By the way my bolt is going on 5 years and 99.9% one peddle driving. Corrosion is not in the cards in this area. Mummification is another story.

It is a scam, but Porsche claims that the brakes and rotors are only rated for 6 years.

The pad replacement interval is six years (as other mentioned above a few times) worn or not. The rotors don't need replacement until worn, which I have heard quoted variously as "30% longer than steel" (says Porsche, being typically conservative), "50K-70K miles" (Macan reference, without regen), to "100K+ miles" on a Taycan given regenerative braking.

My replaced PSCB Taycan rear discs at 29,100 miles are pictured below.
Delamination of the surface coating had occurred on one inner surface.
The other 7 surfaces were ok.
This was considered normal wear and tear.
I wouldn’t again have PSCB.

The advertised claims of increased longevity are not always achieved.
The replacement cost of PSCB discs and pads is about 3x standard brakes.
Obviously all disc surfaces had been exposed to the same usage and environmental factors.

The damage was not identified at the scheduled service 6 months earlier.
There are product safety implications- because all of the outer surfaces and all but one of the inner surfaces were ok, there is a chance that delamination such as this would go unnoticed, more so given the contribution of regenerative braking.

I would have kept pushing for warranty claim.

Wouldn't have a hard driving session with new calipers cleaned off the rust?

This seems disingenuous...

There's also detailers that can clean off the rust.

I wonder how to even check mine, since that's on the not visible side... I guess without removing the wheels, not possible.

But this seems extremely disingenuous. Especially at 30k miles, I would have pushed for warranty claim. Especially since you checked 6 months prior, they should have checked the brakes and informed you... which tells me they never checked them.

Also, in your picture, only 1 of the discs has rust on it, and it seems surface rust, easily cleaned by a hard driving sessions. The middle part rusting is absolutely normal and nothing out of the oridnary that would require chaging the discs.

@chun - with standard discs it may be possible to clean off light corrosion, but in my case, the tungsten carbide surface coating, specific to PSCB, had delaminated.

Also going through this at the moment. PSCBs with the rear right disc/rotor only showing excessive wear on the inside disc. Pics attached. Porsche Swindon are already trying to wash their hands of me - pay up or refurn the loan car immediately. Offered trivial discount even with a claim to Porsche GB. I am continuing to push back as the vehicle is a 21 plate with only 34k miles on it. Never tracked and since I’ve had the vehicle I’ve complained in emails to their service manager and dealer principal of rubbing/grinding noises which sound like the brakes. Low and behold now they want thousands to replace pads and rear discs! The german youtube video - ive raised those points and they are just dismissing everything I say and just pointing to ‘external factors’ like a stone chip has caused delamination.

Personally, from what I can tell in the photos and from other research, is that the pads are faulty and may have hairline cracks which has caused uneven wear. My inner disc looks just like the German guy’s explainer. They are refusing to show me the pads without charging me more…

What to do at this point?! I am leaning towards independent examiner and taking them to small claims/ombudsman for this.
