In 2019, Porsche made a bold move by introducing the Taycan - its first modern-day EV. I say “modern day” because the first EV to be designed by Ferdinand Porsche was the 1898 Egger-Lohner C2 Phaeton. But this is a topic for another time. The Taycan became a global sales success and won numerous awards, including the “World Car of the Year” (2020) and Car and Driver’s “Best EV of the Year” (2025), to name a few.
The model quickly became the go-to performance EV for those looking, not just for impressive numbers (you have the Tesla Plaid for that), but also sports car-like handling. But not all is perfect with the otherwise great Porsche Taycan. Some owners continue to report issues with the Taycan’s dreaded engine control malfunction, and I recently stumbled upon another complaint, made by an owner, concerning the car’s brakes.
The issue was first mentioned in the Porsche Taycan Owners Club, where the owner posted a video of his EV, making a very loud squeaking noise every time the brakes are used. Any unusual noises that come from the brakes warrant concern, but it turns out the owner’s concerns may be unfounded.
The “issue” that may not be an issue
Many Porsche Taycan owners opt for the PCCB (Porsche carbon-ceramic brakes). These are high-performance brakes meant to provide superior stopping power during hard driving, such as on a racetrack. They are also much lighter (usually by at least 50 percent). There are two caveats to this, however. Carbon-ceramic brakes perform poorly when cold, and they often tend to produce loud squeaking noises. This is exactly what is happening here.
This particular Taycan seems to have the PSCB (Porsche surface-coated brakes), which means these are cast-iron brake rotors, coated in a reflective tungsten-carbide layer, for reduced dust, corrosion, and fade.
Porsche cars equipped with the PSCB option typically feature white brake calipers, but you have the option to have them painted black, likely for a stealth-like look. This owner has ticked the black brake callipers option.
Should you worry?
The more keen members of the group are quick to point out that this is normal behavior for the PSCB, especially at low speeds, after the car has been sitting. This is very similar to how carbon-ceramic brakes behave, as they need to get up to temperature for maximum efficiency.
Some members suggest that the cold and wet climate is the cause and that it should go away after a while. Another member recommends a bit of spirited driving with the regeneration function turned off. It is well-known that EVs feature regenerative braking, which essentially allows one-pedal driving due to strong “engine braking”. With the electric motors doing most (or all) of the stopping, the brakes aren’t working a lot.
As one Taycan owner from the group points out: “This is the challenge with combining brakes that were designed for high heat/stress conditions in an application where they get very little use. Just need to give it a spirited drive with regen off.”
Porsche’s brake-squeak issue is a hot topic on Reddit, where owners are looking for or providing insight to anyone who is only now coming across the issue.
Another group member says: “They are high performance race brakes. They all make noise. Once driven a bit, it goes away!”
Another Facebook user chimes in by putting any concerns to rest: “More or less normal with PSCB. Especially in damp conditions.”
This isn’t anything new, but it seems that anyone’s concerns are quickly put to rest once it has been made clear that this is normal behavior for performance brakes. Hopefully, this article serves to explain the issue to those who are new to the specifics of performance brakes. I always invite car enthusiasts to share any insight or their experience in the comment section below.
