If you want to change your bleeders, it's a pain in the butt to get air bubbles out.
With the Vac you can just drain the fluid change out though the speed bleeders and it's done... and any fluid change after that is a non issue, time or work.
Wow... I think I just sold myself on that....... :tongue:
I've used both, the Mity-Vac is nice if you're in a professional environment, but if its something you're just gonna use once in a while, theres no reason not to pickup the harbor freight unit.
Thanks Monk. Lemme see if I understand you correctly. You're saying:
"If you just change the bleeders to speed bleeders, it will likely introduce air into the lines and that's a pain (and kind of defeats the purpose.)
So if you change to speed bleeders-get a pump too."
I think I get that. I'm kind of interested in the converse:
If I get a Mity-Vac (or cheaper substitution) is there any point in speed bleeders too? I can only think that they would be a benefit when I don't have access to the vacuum pump.
There's nothing to say that the Mity-Vac is fool proof. The lid on mine wasn't very sealing well and would not create a vacuum, until I put enough pressure on the lid to help create a tighter seal. Once I did that it worked great. I would think that speed bleeders would be ideal for quick bleed jobs but that the vacuum bleeder would make replacing the fluid much easier. I would then think having both wouldn't be detrimental.
Speed bleeders and MityVac are two different things in my opinion.
Speed bleeders are great if you are unable to bleed your system by yourself. They make the process a whole lot easier and faster. But, there are ways to do it solo, bikes and cars, without a speed bleeder. So it's only worth it if you're going to be doing it often, like if you're someone who bleeds it if it becomes the slightest bit spongy.
I use the MityVac more for just having something on the end of the nipple sucking all the fluid out when I open the bleeder. Makes sure nothing dribbles out and on the bike. The fluid chamber makes it really easy to dump into another container as well. I'd spend the money on the Mityvac. An extra $10 for a product you know is going to work vs getting frustrated with a cheap broken knockoff.
I'm a fan of speed bleeders. Havent needed to use the Mity-vac since I switched over.
What I'm wondering (I'd be changing it solo)........ Isn't a lot of air involved changing to speed bleeders? There-for warranting having a vac to replace fluid and get all that air out of the system............ where after having the SB's installed and with fluid done, it would just be a matter of sticking the tubes to the SB's and use the vac?
Speed bleeder work great! No vac is needed. No air will get in the lines if you don't open the fluid reservoir until you have the new bleeders in place. If any should, it will come out with the old fluid.
They are super easy to use, all you need to do is pump the brake or clutch, and keep adding new fluid to the reservoir, as you pump the old fluid out. Hope this helps.
I have used all of the options, but my favorite is this one, it also makes complete fluid replacement a breeze, including cars. http://www.harborfre...eder-92924.html

I'm missing something here... If I'm riding my bike and apply the brake nothing comes out the bleeder(if I had SB's).... but changing the fluid I pump the brake and add fluid and the old stuff comes out the SB....... how?

You "crack" the SB open about a 1/4 to1/2 turn to actuate the SB. Once you pump the brake it allows fluid and air excape. When through tighten SB and your done. I use a small length of tubing to direct the fluid into a jar or pan.

Thx, like doing a regular bleeder, w/out the tightening/loosening, repeat thing, sounds good, most have a ball and spring in it?
So after much (probably way too much) deliberation, I decided what I really need is speed bleeders. I'm really anal about any sponginess at all. The MityVac is probably in order for the full fluid change but the SB's are what I need for now.
I got them from Tightwad so he'll send me what I need for my 5th gen. I am interested though if anyone has specific info about using them with the linked brakes. Like, for example, I assume one goes on the proportioning valve? Will I need to pump the secondary master cylinder by hand? Should I go with the bleeding order that the manual recommends? Or does that matter?
A. right front caliper outer
B. left front caliper outer
1. right front caliper center
2. left from caliper center
3.PCV valve
4. rear caliper center
5. rear caliper outer

Its a basic check valve, so just crack it open, pump till the bubbles are gone tighten it up. - No tightening/loosening routine. Nice.
I made my own power bleeder with a 1hp wet/dry vac, compression fittings, some clear tubing, and a pickle jar. It works so good that I threw my MityVac away after using my own bleeder for the first time.
