I have a BK Warrior 9920 + Feigeo 9L, which I got about 3-4 years ago from RC-Monster. Since day one it has had brake fade (brakes stop working at the hint of the ESC getting any warmth). I didn't drive it much so i didn't care.

However, I'm driving it a lot now and it's a dangerous proposition to drive my 11 lb e-maxx with no brakes.

Since it is no longer under warranty, and I don't feel it is worth the expense to send it in for repairs, i was curious:

Is there a specific component that I can replace that will fix the brake fade? I have tried contacting BK directly, but I have not heard back. I have worked with surface-mount components before, so I am confident I could replace said part... if I only knew which one?

I have tried putting a fan on it, but that just delays the brake fade for a few minutes.
