Anyone using Mityvac 7300 for brake bleeding/flushing?
2006 Ultra
The Mityvac 7300 is the compressor-air driven unit. Works great for me for draining my engine oil but I have not tried using it to bleed the brakes. It works quite fast for the engine oil, maybe 5-10 minutes to get out 3.5 quarts.
I was hoping that someone could tell me their experiences using it to drain and renew the brake fluid. How did the brake-bleeder hose attachment work? Did it leak fluid or allow air into the system? Did it pull fluid too fast to keep the flulid reservoir filled quickly enough? I know there is an air flow valve on the unit that to some extent will control the suction, but I wondered if it was variable enough to control the rate at which the fluid was extracted. When doing engine oil I have this valve full open of course.
Thanks in advance for any reports on this.

Why mess with it? The speed bleeders do the job fast and without any extra tools.

I have thought about getting the speed bleeders. I like the stainless version. One question is: when first installing, that is taking out the OEM unit and replacing with the SB, how much brake fluid comes out before the new one gets screwed in?
It would seem that it is important to make certain to work relatively slowly to ensure than the threads are not crossed before wrenching it in. Then, what size tubing and what kind attaches tightly to the SB to ensure that that no fluid leaks from that juncture while doing the bleeding or complete replacement.
I want to replace all the brake fluid, not just bleed the system. My brakes are just fine now.
Any advice on using the speed bleeders will be appreciated.

I completely flushed and bled my brakes with these bleeders. It takes five or six minutes per caliper. Just keep filling the master cylinder with brake fluid and slowly pump your brake pedal or lever. Once you see there are no bubbles in the tubing, then you are done.
