IMHO, you can use vac or pressure bleeders all you want (not 100% reliable in my experience, the vacuum ones anyway), but in the end, you need to finish off with a conventional squirt.... and Speed Bleeders do not allow backflow of air or fluid from your bleed hose. The threads are sealed and there's a spring-loaded ball in the bottom..... However, the system must be full of fluid ahead of time, as that ball valve needs to see some fluid pressure to work. I love SpeedBleeders, nothing better IMHO.

They are great for replacing fluid, as they can quickly suck out the old fluid from the MC without a mess, as well as pull fluid through quickly. They are especially nice for doing an auto or truck, where there is a lot of fluid to move.
So what if it sucks air around the bleeder threads? This air doesn't get in the system. And if you really don't like it put a dab of grease around the threads. Thick grease is not going to be sucked in and will block entrance of air.

Am too lazy right now to download the manual from HF but IIRC the bleeder wants 65 or 100 PSI. If your pancake compressor can sustain those pressures then all is fine. I doubt it, the bleeder requires a large amount of air.

I've done that, but still gotten a steady stream of air. It's not a big deal, I use it when replacing fluid. Even though bubbles are showing, I know it's bled due to the amount of fluid moved through.
I spent most of my money on guns, motorcycles, women, and whiskey. The rest I just wasted!
