Just received the pilot part.
I'll install it into my Twizy, set the powerbox to stage three and go nuts on them, drifting, full braking from top speed, light braking at high speeds and constant power braking till the battery goes dry.
Then I'll take en out and inspect them for leaks of other possible problems.
In will only wear it on one side so I can compare it to the stock piston on the other side in terms on pressure or less/ more friction and retraction when pedal is released.
In other words, I need your patience for another week until I am absolutely sure these are safe to use;)
Thank you for your understanding in advance.
