TLDR: Went to a trackday months ago, brakes feel soft ever since. What to do?

Early summer, I went to a track day on Hockenheimring right after my first year service appointment. The car felt great and I pushed it as much as I could. Hockenheimring has quite a lot of heavy braking spots and admittedly I didn't bother with pushing one lap and cooling down the next lap. While I was on track I didn't notice much brake fade during most of the 4 sessions of 15-20 minutes of driving. On the way back on Autobahn, I noticed straight away how soft the brakes felt. I even had a scary moment where I had to brake from 200+kmh on the Autobahn and car braked much softer than I am used to, I took it easy afterwards.

I thought it would get better after everything settles down and frankly I couldn't drive the car much this summer but whenever I enjoy it on a backroad I can clearly notice how smooth the brakes feel. The bite feels much more gradual and less "bitey" than it was before the trackday. It still stops, probably as well as it ever did but I don't have the same confidence I had before the track day and I simply prefer a bitey brake feel I guess.

I checked on the pads and they seem to have some life left still. I am at 13k kms, at most 3k of it was spirited driving.

I read a similar post on the other GRY forum and people suggest I cooked the brake fluid and need to adjust/flush it. What is the most cost effective way to solve this and restore the original feel? Normally I am okay with investing in the brakes but I am being let go on the 15th so I would like to spare some $.


Any tips appreciated, thank you!
 
I had something similar after a hot trackday with the original pads. I had to clean the discs, the pads had totally changed the color of the discs and there was a lot of baked on pads-material.
I used a handheld drill with a scotschbrite wheel drill, no problems after that ...until it happens again 🥶 . Honestly, sometimes it happens even with Carbotech 8XP but then I just drive and brake more agressively and it goes away

Change the brake fluid. It’s cooked.
Often even small brake fluid bleed / refill helps to refresh the system after track session. so It's a good habit to do if you notice any fatigue in brakes. + that cleaning of pads and discs.

Do you do these yourself or do you take the it to somewhere? I have never done any brake work on the car before (or any serious mechanical work for that matter) 😅.

Thanks for the tips and pictures. I will have to find where can I get this done. Currently, I don’t even have space to remove a wheel, let alone the discs 😅
 
I've bled and replaced brake fluid myself before, but it's messy and annoying and I don't relish doing it again!
