always keep the pump higher than the bottle to avoid fluid going into the pump. also helps to have the bottle higher than the bleed valve. never let the main resevoir get lower than minimum if air gets sucked in u have to start over

That black packing piece on the HF pump should have a "Remove Before Using" sticker on it.

It seemed like there was still a bunch of air in the system when you started the test/comparison.  Since you used the Pittsburgh bleeder tool first and you could see it pulling lots of air bubbles out of the bleeder valve, it naturally resulted in having less fluid in the Pittsburgh bleeder tool's collection bottle.

Still, my interest was to see that both bleeders did in-fact work the way they were supposed to work.  Also, since I am not a professional mechanic and I rarely work on brakes, I don't feel the need to have the "most comfortable" tool produced.  As long as it can do the job, that is good enough for me.  I mean, if I have to pump the handle a few extra times because I bought the Pittsburgh tool or if the handle isn't quite as ergonomic as the MityVac, I think I will manage.  I can always wear gloves and watching your video, it looked to me like you had to pump the MityVac more times to achieve the same pressure anyway.

Don't get me wrong, I am all for buying good tools that will last but I think the Pittsburgh bleeder tool is good enough for me.  I am going to go to Harbor Freight tomorrow and buy one so I can bleed the brakes on my RV after I replace the front brake hoses.  I have a feeling it will perform flawlessly (as long as I don't forget to remove that infernal spacer, lol).  Wish me luck!

The Pittsburgh will do just fine It's not like I'm doing break bleeds every week.
Very well done presentation. 👍

I have an older Mityvac and it broke at the plastic catch on front end. Later picked up the Harbor Freight vac pump and have not have any problems after several years.

We regularly use the mightyvac at work. You have to disassemble them periodically because a any slight amount of brake fluid getting into the cylinder makes the rubber inside drag against the plastic. Also, the little pin that holds the handle to the internal piston constantly falls out if the piston gets stuck in the pulled position while the handle returns to the released position.

tbh I didn't notice the ring in the first vid either.  I was confused though I was like it should work better than that.. even the cheapo ones can usually get the job done.  this is a much better comparison!

Good review and saved me a lot of time in learning how to use one of these pumps. Thank you

have a harbor freight one, after years of having it, the capture container does not hold vacuum. had to put grease on the O ring to get it to hold.  Looking for something better to bleed brakes,  review was good information.

I know this is old but I paid $15.99 today at Harbor freight for Christmas promotion regular price was $34.99 ... I have 4 cars to bleed including my Ford E250 cargo van... I luv Harbor freight

This was to close and near, lol. I love it though. Well thought out and you owned the last Pittsburgh debacle points... Thanks Pete...

I’m going w the MightyVac based upon this video and it’s comments. I’ve been beating my head against the wall trying to get me ATV brakes pumped up right and it’s killin me. Thx for all the tips here

Nice looking Porsche. The 944 is surprisingly practical.

Thank you for viewing both of them I liked the way you did and sharing I go with a mighty vac I never bleed brakes myself and always had someone pump the brakes. With me I think it's harder on the master cycender  that way.

I brought the mityvac because of the quality and accessories ,haven't tried to use it yet

Nice comparison. Worth watching.

The less priced one (Pittsburg) seemed to suck all or most of the air out first. The more expensive (Mity Vac) one can have more fluid than air. Pittsburg did the burping and Mity Vac got the solids.

Great comparison- you did a great job. Thanks.

Thank you for the comparison and the excellent quality as well as informational vid

Thank you for the comparison and the excellent quality as well as informational video. It seemed to me like the Harbor freight item had a good deal of air in with the fluid therefore it thoroughly bled the brake line prior to the MityVac test which would have removed all fluid filling the container with more brake fluid. I could be missing something though.
