I had the same question last night but I didn't ask, because I didn't know how to post my question without offending you.

If I need to extract small amount of fluid from power steering reservoir or brake fluid reservoir or coolant reservoir ... I use the pump from the big shampoo bottle. I use Mityvac 7201 for everything else.


From you there'd be no offense taken. For tasks like extracting small amounts of ATF, it works like a champ. For brake bleeding, and certain diagnostic chores I thought it would be a good tool to have, especially for only $20. The Miti-Vac gets it's fair share of uses like draining the transmission pan before a pan drop. I used it to drain coolant because I didn't want to remove a lower radiator hose or mess with the petcock on a few older cars I helped friends with. It was also nice to use to fill a transfer case, and the M5OD transmission on my van. It is also a good tool worth having.

I recycled a damaged bottle from the Blackstone oil kit. I glued two brass inserts (watts, A-8 96760-PT,1/4" OD) in to the bottle cap with epoxy. Now I can extract oil directly into a new bottle without draining my oil. The other good thing about this bottle cap is it also fits with many 1 quart oil bottles.


Good idea!

I thought this might be interesting, it is just one test you can do with this tool. I picked this up of the web a while ago, thanks to whoever wrote it.

Vacuum Brake Booster Testing and Diagnosis
This procedure will require the use of a hand operated vacuum pump with a vacuum gauge.
If you do not own one it can often be rented or borrowed from most “big box” parts stores. (Note:
18”HG is the minimum engine vacuum at idle in gear to effectively operate a vacuum booster

1) Remove vacuum hose from check valve on booster. Place hose from vacuum pump onto
check valve and draw booster to 20” of vacuum.

2) Let booster sit with vacuum applied for 5 minutes. If vacuum does not stay steady at 20” it is
faulty and needs to be replaced. If vacuum does hold steady at 20” proceed to step 3.

3) With 20” of vacuum in booster depress brake pedal once and release it. The booster should
transfer some but not the entire vacuum in reserve. Depending on how hard the pedal is
depressed it is normal to see 5-10” of vacuum depleted from reserve. The most important
thing is to ensure the booster does transfer vacuum but does NOT transfer the entire vacuum
in its reserve. If vacuum remains at 20” OR goes to zero the booster is bad and will need to be
replaced. If vacuum transfer is within the above parameter proceed to step 4.

4) Once again draw booster down to 20” of vacuum. Go inside car and depress brake pedal and
hold down for 30 seconds. You should see the gauge drop slightly and then hold steady.
Vacuum should stay steady as long as you are holding the pedal down. If vacuum drops while
pedal is being held down the booster is faulty and will need to be replaced.

Ok , I get it and I totally agree with you.I don`t think I get my Mighty vac cleaned up real good.

I own the "real" one. It is made by MightyVac and is called Silverline. This is the tool on which HFT is based upon. HFT is metal one too, so it must be good too. Lately, MightVac sells cheap plastic ones.

It appears to be well made.

Too little volume to do a lot. A MityVac 7201 with brake bleeder attachment is a much better solution.

A little more volume would be nice, I'm working on that. For sucking out a small amount of ATF in a transmission that was overfilled it was perfect. I have the MV 7201 and didn't want to be bothered taking it out, let alone clean it. For bleeding brakes I think it will be fine too. For anything with some real volume the 7201 would have come out.

A suction tool is useful, but I can't see the benefits for bleeding brakes. What am I missing?

You connect a hose to bleeder valve, connect that hose to the main tube of Mityvac, connect the main tube to Mityvac container. Pump the Mityvac 4-5 times then loosen the bleeder valve by 1 turn, brake fluid will start draining into Mityvac container, keep an eye on reservoir and top off to max line 2 times, you are done on that wheel. Go to next wheel.

I use mine as a mini-extractor... I prefer the traditional two-man or a pressure bleeder.

Few youtube celebrities have claimed that tube submerged in the brake fluid works as good as two-man or pressure bleeder to bleed the brakes. Watching them do it makes me think it is the easiest and safest method as you the one man controls everything and has the least probability of something going wrong. Pump the pedal by hand few times; that way you will not force the pedal to travel to never never land.

I did too I loved pressure bleeder, about 10-12 years ago.

I bought Motive Power Bleeder with all accessories for may cars at that time: 1994 Lexus LS400, 2000 MB E430 and 2004 Honda S2000.

I tried Motive Power Bleeder on LS400 and E430 around 2006-2008, it worked okay with front wheels but didn't do much for rear wheels, the rate of fluid coming out is as slow as gravity bleed. Also, it is time consuming connecting the accessory for LS400 (the one with short chains).

Why should I waste time connecting the pressure bleeder to the brake reservoir and then wait up to 1 hour for each rear wheel ? With Mityvac I can bleed both rear wheels in less than 10 minutes(I am slow and I am very careful working with corrosive brake fluid)

To me, using Mityvac 7201 to bleed the brake is easy and fast and no chance for error and absolutely no mess, raise the car, setup jack stands, remove/reinstall the wheels ... are hard works.

It may, but I already bought Mityvac 7201 to do oil change for my E430, why not use it to do the brake ?

There's nothing like feeling comfortable using a good tool! Especially when it can save you a lot of time.

Thanks. With a pressure bleeder, you replace the fluid in the reservoir and then pressurize with the pressure bleeder, go around to all four corners and pull fluid... Done.

I'm not really saying there's a wrong/bad way, it just seems to me that pressurizing once is slightly easier, and you can flow more, longer if desired.
