I have this MityVac Brake Bleeding Kit but have not used it. Has anyone use it and is it easy to use?

The Fluid Evacuator Brake Bleeding Accessory Kit is design for use with Mityvac Fluid Evacuators, P/Ns 07200, 07201, 07300 and 07400. It is provided standard with P/N 07300, but must be ordered separately for the other evacuators. The joining of these two MityvacŪ products produces a quick and easy method for one-person vacuum bleeding of hydraulic brake systems. This Kit includes a durable brass flow control valve and universal brake bleeding adapters that will fit most bleeder screws. SEE PHOTO.

I've never used this, but I'm just not a fan of bleeding brakes with vacuum. This gadget might be handy when bleeding a clutch or some other unusual situation. It might work okay for flushing, but I'm a little leary about it getting all the air out of a modern ABS system that has been opened and has lots of air.

For all I know it might work great, but I would have to reserve judgement.

I prefer good ol' two man brake bleeding, but I often use a pressure bleeder because there never seems to be a helper available when I need one.

Good luck,

I've used the MityVac for brake bleeding and cannot recommend it. You must have a really tight seal at the bleeder screw or it will suck air in. I even had one suck air in through the threads on the bleeder screw, so I kept thinking there was air in the system when there really wasn't. Get a Motive Products pressure bleeder instead.

Re and Re the brake fluid today and here's how I (one person) did it.

1. WD140'ed all four caliper bleed screws
2. Raised the car on all fours with jack stands
3. Removed all wheels (rotated them after)
4. Removed all bleed screw caps and wiped clean
5. Connected the Bleeder Kit (valvel turned to Off) into a Fluid Evacuator and pumped it about 20 times to build vacuum
6. Connected the other end into the bleeder screw
7. Removed the cap off the brake reservoir in the engine compartment, wiped clean the area, top-up the reservoir with fresh brake fluid to slightly above the maximum level
8. RR caliper - turned the bleeder kit to On position and loosened the bleeder screw (about 1/2 turn) and fluid started to drain.
9. Kept watch the reservoir ensuring the fluid level do not fall below the maximum level too much by topping it up every so often with fresh brake fluid
10. RR, LR, RF, LF was the bleeding sequence I followed.

Note: The brief instructions that came with the kit indicated that small tiny air bubbles maybe seen through the clear tube while bleeding (caused by air being suck-in through the bleeder screw) but suggests that there's no air in the system.

I've consumed about 1/2 liter of fluid in the process and my reservoir has clearer fluid. Nice. Brake pedal function works and feels the same. Having not done it before it is an easy job, but I hope I did it all correctly.

How will you prevent the fluid draining when you remove the bleeder screw to wrap teflon tape?

I wouldn't screw with a mityvac for bleeding teh brakes. It's too easy to make a pressure bleeder out of a cheapo, 1gal home garden pump sprayer, a Mercedes brake reservoir cap and a 1/4" MIP x 3/16" barbed fitting.

Haw, if you have a parts car, the reservoir cap is basically free.

I was astounded how easy and fast I could flush the brakes and, it even worked on my clutch...once I correctly installed the disk.

The Kit connects to the fluid excavator. See photo.

I also use the fluid excavator to do oil changes, etc..
