1. First, put your mouth on the bleed fitting.
2. Second, suck real hard until you get a bad taste in your mouth. :bird: Just kidding.
I've tried before to bleed brakes systems with new lines, etc. with absolutely no success...but that probably has more to do with no patience than anything else.
Go to autozone or advanced and buy a Mighty Vac...it is one of the best tools you can buy for under $30.00. I use mine all the time on cars and bikes. Takes away the need to have someone there pumping and holding....pumping and holding...pumping and holding... :waytogo:
