PSCB Grab
Hi folks,
My (new to me) 2020 Turbo has PSCB, which I believe are standard on the Turbo. I have to admit that I've been having a tougher time than I expected adjusting to how much they initially grab. I like strong brakes but I wasn't expecting them to be so grabby with very little pedal push. When pulling into the garage, etc it's quite difficult to do so smoothly. I just want to make sure that this is standard behavior for the PSCB and that there isn't something wrong ...

standard behavior, though doesn't happen consistently
I had a lot of miles on my 911's PCCB, so used to a grabby brake.
Hard though, when you're trying to be careful pulling into the garage.

Keeping them clean helps a LOT, as does keeping them warmed up.
PSCBs are wonderful brakes when they are hot, but getting heat into a Porsche's brakes in street driving often entails risk to one's driver's license and/or sheetmetal. I've resorted to dragging the brakes for a quarter-mile or so on occasion. That works... for a while.
Edit: another tip that helps keep you from looking like a spaz in parking lots and drive-thrus: switch the drive mode to Normal temporarily. By lowering the idle, this will help you stay off the brakes and enable smoother driving/parking maneuvers at very low speeds.

They are grabby. And it is somewhat inconsistent, as in sometimes they grab more or less so. I have not found keeping them clean makes any noticeable difference however others here and in other threads have stated they felt it does. They are great brakes otherwise.

Wow, that's interesting. What year is your Macan? and are they definitely PSCB, not PCCB?

2024 GTS and they come standard with PSCB's. What I don't know is if Porsche changed pad compounds from those of the previous years with PSCB's due to complaints and now the 24's might be slightly less grabby? I'm not complaining about the effectiveness of my brakes either. I just wish mine had more initial bite.

Ok, update on this. I had the dealer evaluate and they said the brake system looks fine. They checked fluids and said levels were good and fluid was in good shape. They claim they didn't top any off or lubricate anything. But the grab is completely gone now. Scratching my head on this one. It's a night and day better now. Braking is completely linear now. It almost doesn't bite enough now, but at least it's linear. I'll take it.
The only thing that was fixed while it was there was they replaced the front passenger air strut which was leaking. Anyone have thoughts on whether a leaking corner on the air suspension could have caused the brake grab to begin with?

That is damned interesting, because it's exactly what happened to me. Dropped it off for its first oil change, and when it came back I had to double check to make sure they had given me the right Macan. The brakes felt absolutely perfect. It didn't last more than a couple of weeks before the old grabby behavior started to return.
I couldn't see how anything could have affected them except for the fact that they had washed the wheels. And in fact, for my car at least, a good wash does restore smooth braking for a while.
