So, I noticed, after 6-7 laps at autoX yesterday, that there was a bit of brake fluid pooled on my engine bay cover that sits over the brake fluid reservoir; anyone else ever have fluid forced out the cap after repeated hard braking?! Brakes feel and work perfectly fine. Possibly the rubber seal shrinking/going bad under the cap?

Saw this happen on an AP2 during autocross -- how hot was it, and was the reservoir overfilled??

Come to think of it, it may have been overfilled due to the recent flush/bleed I did. I'll keep tabs on the level next weekend and see if it recurs...

I'd say it was overfilled and the fluid expanded under hard use. Get yourself some reservoir covers like Mugen or Spoon for extra protection, they actually have a purpose despite people using them for cosmetic reasons.

I appreciate the knowledge lmao! I always wondered why people ran "socks", makes perfect sense now...

The only time I have boiled over I was over filled and that wasnt even on a track

I think the seam in the middle tends to leak. Thats where i see a little bit kf fluid in mine. I ran over a checked a CR at an autox once and it was in the same place on that car despite being 5 years newer

Hmm. I will fully investigate and diagnose/pinpoint this if that's the case, for future reference...
