Spend the money for a mity vac and solve the problem. Use a paper towel to soak the dirty fluid out of the brake and clutch master cylinder then fill it with new fluid. Mity Vac is a small vacuum pump with a hose and rubber fitting to go over the bleed nipple then you pump and it pulls the new fluid thru. It is easier if you have someone to keep pouring brake fluid in while the Mity Vac is pulling the clean stuff thru.
Yes I know that is not what he asked but it is the easy and quick way. The pump the brake and clutch levers is old school.
Yea I have the Mityvac lol...

He's merely concerned about getting a good seal from the bleeder to the piece of tubing the old brake fluid will be collected in. The proper size tubing should do. I have never had a problem with fluid or air getting past.
chillax, teflon tape around the threads will ensure a snug fit. yes it the tube is the correct size it should, but sometimes it does get stretched out as you go from the different bleeder ports.
if he had speed bleeders he wouldn't have to worry about air getting into the brake lines.
GTS have it your way and yes I admit the Mity Vac may not be the most durable of tools but I will put it up against the old fashion way any day.
I understand I seldom post here but the good thing about lurking on different boards is seeing what different people do for different problems so if I happen to get somebodies bike in my gayrage I might already have an easier way to fix them with that info.
It does not matter how the original poster bleeds his brakes and or clutch as long as the end result is they work.
Later People and hope youns all have a good holiday month

wow, get up on the wrong side of the bed today?
Yes, it will, of the bleeder/caliper itseld. Sealing the threads of the bleeder with teflon tape isn't going to help avoid fluid leaking past the bleeder and the tubing.
The question had nothing to do with sealing of the bleeder threads. He never asked that, and he also never said he removed the bleeders. All he wanted to know was if the method described would ensure a better seal between the tubing that is collecting the used brake fluid and the outside of the bleeder.
Also,
Not my fault you misunderstood the question and offered flawed logic.

The end result when using a MityVac isn't anywhere near the quality of a manually bled system. Maybe you just have low standards or don't mind brake fade, but I have a huge problem when my brakes turn to shit after a few laps.
Yes, I have used MityVacs, and yes, they are a terrible product. Not only are they poorly made, but they don't get the job done properly.

GTS the brake fade is probably heat and nothing to do with the Mity Vac but then after scouring the board reading different postings in different threads it is apparent that you are the man that has done it all and no one else should have an opinion different than yours.
I am not a professional wrench and it has been a hobby for many years. I still have fun with wrench weekends in the gayrage and my standards are to make peoples bike safe before they leave.
If you want a pissin contest then go for it but you will just be pissin on your self because feeding the gold fish isn't worth ones time.

Brake fade happens because any air trapped in the system boils due to the extreme heat generated. Using a MityVac is doing the job half assed and you will not get the results you would by doing it the right way. Leaving air in the system will ensure brake fade.
And yes, I have bled brakes many many times, and am somewhat of an expert at extracting every last bit of air from the system. Would you like references for the brake systems I have assembled and bled for AMA race teams?
MityVacs being inferior to bleeding brakes the proper way by hand isn't an opinion, by the way, it's a fact.
