Ghetto improve the brake fluid
 

Hi everyone
Today we decided to leave for the Nurburgring tomorrow evening.
As usual i was slacking on prepping my Cars, so i have to take the Z.
I have Endless Brakepads which i'll install tomorrow morning and break in during our drive there (6h).
I also have a bottle of Motul 666 here, would it be beneficial to drain the brake fluid reservoir and fill it with Motul?
I don't have any tools to flush/bleed and in this country you can only order such tools, which won't arrive tomorrow.

Thank you in advance!

Not doing a bleed and flush won't do any good. Just keep the reservoir topped off.
