Anyone upgraded brakes/brake feel? Too soft!

[WuffvonTrips]

Put Taycan on charger one night and accidentally direct charge was enabled. So it didn't take my usual home charge profile of 85% and charged to 100%

Get in Taycan and drive the next morning at 100% and its like a magic fairy fixed my brakes overnight. It was INSTANTLY noticeable from the moment I set out of my garage. Nothing changed between parking except the SoC.

The braking felt close to mechanical with instant response and stopping power. I barely had to apply any pedal pressure to get deceleration. Huge contrast to the amount of pedal travel required less than 24 hours before.

As my SoC depleted the terrible brake feeling started to come back little by little.

Once my SoC went below 90% the awful brakes were fully back to how they were previously.

Also the amount of green recouperation displayed in the center gauge is barely visible when at 100% SoC. I live on top of a valley and to go into town my entire drive is downhill. My individual profile is set to always have recouperation on and I am very familiar with how much recouperation is normally displayed on the meter when going down the hill under normal battery SoC which is always 85% or less.

That is indeed odd- even allowing for your downhill run adding extra energy, it sounds like your Taycan isn't recuperating as designed. For one thing, it should initially (I don't know if that's per trip or day) be using 100% mechanical braking, regardless of the % SoC (to help clean up the discs).

New PCM control unit with new code + new hydraulic unit fixed my low speed braking issues as I stated above.

Taycan slowed before and after as it should using recuperation as designed by Porsche (ie no where near our Tesla’s 1 pedal driving) and displays on the center gauge correctly except when charged to 100% then it’s minimal at best.

AFAIK PCCB does not require cleaning up aka wiping like a rusty steel rotor does.

I too experienced the "spongy" brake feeling at slow (parking lot) speeds and also the weird "goat" sound as the car came to a stop. Finally on a particularly hot day in late July got the "PSM Falure Visit workshop, Continued driving possible with adjustment" error display. Champion Porsche in Pompano Beach kept the car from 9-Aug-2023 to 25-Sep-2023 (i.e. 6 weeks and 5 days) to figure out that the brake fluid needed to be flushed and an software update needed to be performed. Was told by the SA just prior to picking up the car that the software update was a known issue "campaign" to fix the brakes.

I love my recently acquired Taycan Turbo but the brakes are just so soft compared to my 992 C4S. I wouldn’t expect the same level of braking power/bite, but the Taycan pedal seems surprisingly spongy for an otherwise beast of a car.

Has anyone successfully improved brake feel/bite on a Taycan? I currently have PSCB FWIW.

thanks!

I also just bought a witk 10k miles (moving from a Tesla). I am shocked at how soft the brakes are. In the Tesla the cars slowed rapidly when you took the foot off the accelerator (regenerative). The Taucam does not slow at all by comparison but worse the brake travels a long way and is fairly soft. My two adult kids describe it as dangerous. I assumed we just needed to get use to it until I saw this thread

It shouldn’t feel that way at all. Have Porsche fix your brakes.

Braking is done mostly with regeneration. Nothing you can do.

My Tesla’s had regenerative brakes and was massively effective in doing so. btakes on my recently acquired Taycan (10k miles) seemed frankly dangerous. I am shocked at lack of bite from regeneration and the soft spongy feel

Adjusting to the Porsche system does take a little while. I also came from a Tesla (2020 S). Lift off regen and one pedal braking were excellent.

All initial braking with the Porsche is regen (watch the power meter as you brake). I believe that the hydraulic system comes into play when you exceed 0.6 G deceleration and when you slow to around 5 mph. The regen turned on and off by the button is in addition to the always present brake pedal regen, and doesn't do a whole lot of slowing. The the Porsche is capable of a much higher level of regen than Tesla. Porsche has a problem blending the regen deceleration and hydraulic braking. There is no recall for this issue, refer to TSB 90/21. Not every car, but a lot of cases have been reported on this forum. Some are apparently solved by bleeding the brake system. Mine was fixed with a software update that was issued June 2023. The problem with my car was not there upon delivery and no one seems to be able to explain how the problem developed, but the software update resulted in improved pedal feel and eliminated the car intermittently losing braking at the end of a gradual stop requiring a sudden extra inch or so of pedal travel to restore braking. There is a cure for what you are experiencing. Only time will tell if it is permanent. Head to your dealer.

Thanks - I appreciate the advise from someone with Tesla experience
