My Turbo S finally brakes like I imagined it would, after the brake hose recall fix and 85,000 kms. of uneasy braking feel.

I had the first brake pedal related TSB done (IIRC something along the lines of "brake pedal travel too far"), then the PSM update when it was available. The biggest change in feel was the result of the first TSB, the engagement of regen/decel was much more responsive with less brake pedal application. After the PSM update, the blending of regen and mechanical brakes is much less noticeable with regard to how much you have to press the brake pedal once the mechanical brakes kick in, especially when coming to a stop. Before the PSM update, I felt like I had to press on the brake pedal just a tad more to keep the rate of the decel the same once the mechanical brakes took over without regen--which was a real concern when it's wet out.

My brakes also feel significantly better after the brake hose recall. Before they felt odd, with a noticeable feel at low speeds when the car swapped from regen braking to physical braking. That has gone now and theyre much more linear

Regarding:

worryingly long pedal,

This is a known issue with Taycans. There is a service campaign regarding long pedal braking. It is solved with a bleed or flush & fill. It could recur on your car over time. Just keep it in mind. Here is one of the threads on the subject among others.

I'd be surprised. The software update didn't change the brake feel on mine at all, and I can't think of any mechanism by which it could eliminate a "mushy" or soft pedal.
99.9% of the time a mushy pedal is a bleed problem and with the hybrid brakes on a Taycan there is a specific procedure to get all the air out. There have been multiple reports of mushy brakes being fixed by bleeding properly.

Mine had a software update performed a few months back for the brakes feeling 'mushy', as I mentioned it when I came in for a wheel change. Nothing else is listed on the invoice in terms of brake-related activity. But it fixed the feel of the brake pedal and it was night and day.

Now I am intrigued by what it could possibly be in the software!
Was it mushy all the time or just when going slowly or both?, ie was it mushy when regenerating and/or when hydraulic?

 

[Pozuelo]

Always mushy, which was exacerbated when hydraulic kicked in compounded with loooong pedal travel and braking distance !

My MY20 Turbo lacks the CCB and I wish it had them because the standard brakes suck. My Cayenne has a more confident brake feel and it weighs nearly 1k more than the Taycan. My C7 Z06 has CCB and I've never had an "oh shit, am I going to stop" moment like I've had in the Taycan. It is to the extent that I don't ever use the Sport modes or drive it hard because I'm certain of one thing, the car will not stop on a dime if the need arises.

I received the recall letter but in the same breath, it tells me parts are not yet available.

Wow!
Mine are excellent, I have only had to do one really big stop in traffic and I was very impressed by the braking.
I just had my brake line recall and was concerned with all the stories it may come back worse than it went in but it is just the same.

I have a MY20 Turbo as well and have the PSCB brakes. I have only a few times driven a friends TurboS on the autobahn in Germany and used the PCCB brakes very hard.

In the few times I really had to use the brakes to their limit, I could not find any difference in Performance before the ABS kick in. And I certainly did not find them lacking in performance. I have no more scientific details, but for ordinary road use I am not sure there is much difference in performance between the two types of material. I guess if you drive hard and fast on track, you would find a difference.

Are you sure you are not feeling the difference from different tyre types? Like all seasons vs summer tyres?

I am sure what you felt was right.

On a Formula 1 car the only performance gain from composite brakes came from the reduced weight.
Cast Iron brakes gave identical deceleration (it depends on grip not brake material).

In fact when cold or wet cast iron was better - not a problem in racing but it must have been a big job to solve for a road car.

Also remember that the MY20 had the 10 pot calipers with 410 mm discs ( huge). I find it hard to see that they should have bad performance, unless there Is air in the system or something else wrong.

I know we have had many issues and faults with the Taycan since beginning, but Porsche feel in Steering and brake performance has not been lacking for me at least.

In the last 10 years, I've driven a handful of cars. This Taycan, the MY16 Cayenne SE Hybrid, the MY16 Z06 and a MY20M4. I drive the Cayenne pretty conservative since the electric range meter trained me well (to try and eek out the most erange) The BMW is not my style so I drive it very little. The Z06 I tend to drive like I stole it. The Taycan, from day 3 onward, I drive like I'm going to make somebody's day by rearending them.

The brakes are by far the absolute worst in any car since the TA GTA I had when I was 19.

It was a CPO with 12k miles. Seemed well cared for with the few miles it clocked. I am doubtful air in the line would be an issue unless this was a known factory issue which if that were the case, I'd imagine a more pronounced and measured response from Porsche. Until today when I looked up the curb weight of the Cayenne and the Taycan, Id have sworn the Taycan was the heavier vehicle because when I brake, it feels like trying to stop an 18 wheeler with a tricycle. I was shocked to read the Cayenne is nearly 1k lbs heavier.

There is something wrong with your brakes, and it is probably air. Our 2020 Turbo S pedal is high and firm - perfect height and firmness expected from a Porsche (we have bought five new since 2011, bespoke from the factory).

Have your brake fluid replaced at a Porsche dealer or speed shop you trust. I have driven a TS with mushy brakes at PECATL - it is not normal.

It was a mushy feel all the way down to the hydraulic brakes, which felt far too far down on the pedal. I only had to do a proper emergency stop once, and the *actual* braking performance was superb once I got them to bite, as you would expect. But the pedal felt so much better once I took it in. I'm not saying they didn't do something else (they could have bled the lines), but it wasn't on the invoice, whereas I would have expected it to be. It was pronounced enough by when I put it in, that I was getting a quite concerned. Not sure if it got worse over time, or I just got the point where I felt it just couldn't be what it was meant feel like ?‍

My wife & I have both experienced an occasional “soft pedal” when braking. Yesterday it happened at a normal stop & the pedal was soft and traveled further than normal which was a bit concerning. As soon as I started to move again and then tried stopping multiple times the brake pedal acted normally.
Anyone know why this is happening on rare occasions? Usually a “soft pedal” in any car does not come and go intermittently but the fact the Taycan has both conventional & regenerative brake systems I’m not sure what causes this to happen. I see no fluid on the floor in the garage so I’m pretty sure nothing is leaking. Any thoughts?
