I'd just like to know if anyone knows the size for an aftermarket brake reservoir cap for an E90 , I've heard 45mm, but do you know the part/model # ?
I'm looking to make a DIY brake pressure bleeder for future use since I basically have a sprayer that I was about to throw out and figured let me try it out.

i know someone else has to have done this successfully.

Anyone ever find the cap? BMW cap is 30 bucks + shipping. At that point might as well buy a bleeder...
