Mighty-Vac not so mighty.
Vacula really sucks.

Perhaps a recommendation would be helpful instead of nonconstructive criticism.

ABSOLUTELY!

THANK YOU!

I have used the motive power set-up with aluminum cap and longer hose, coupled with a home-made bleeder bottle set-up. It was used to do 5 cars in a row and worked very well on all of them!

In the case of the motive, the guy had to stop to refill with brake fluid, but that's because he did 5 cars straight.

I am looking to buy one used from a guy for 10 bucks because he doesn't do mech work any more, so I'm gonna grab it at that price.

I hope you are joking.
[I was]

Ok, I conceed, it was lame joke...

omegabenz · #5 09-03-2003, 03:01 PM

If you have used both, then yeah, thats probably fine.

But ok, so vacula sucks, well does it suck good, if it does, then Maybe Ill get that one.

It seems like the motive mighty bleeder is for someone that uses it a couple time in the product's lifetime.

I want something that I can use once a week or more.

"man, my hoover sucks so good it can pick up a bowling ball" Add some details you jokes will make more sense. I thought you were joking anyway.

Thanks,

To be more specific:

I tried a hand actuated Mighty Vac, and it was too slow for efficient bleeding, and does not stand upright on its own. At least on the one I had, the reservoir was too small to do a whole system flush, and I overfilled it once by mistake. Once it got brake fluid in the mechanism, it never operated properly again.
Perhaps they have other models, but I gave up on them.

It was this 'SilverLine' model (like $80-90):

Now looking around, I see they are also marketing a big vacuum transfer pump with the Mighty-Vac label on it. You will see this same unit with like 50 other brand names on it.
I have one that was packaged as an oil extractor (same, but no bleeder fittings). I have the manual one (not the pneumatic).
It sucked oil pretty well, but a 2-foot drop (empty, in its box) shattered the base, and split the container open. I was the clutz, but that seemed pretty weak to me. Never tried it for brakes because I have the Vacula. But hey, the pneumatic one has a different base under the container. Certainly cheaper than the Vacula, holds 6.5 liters, and can be used for other purposes.

csnow

did you guys notice at 6.5 liters it will not hold a 4.2 or 5.6 litre motor. both these use 8 litre of oil.

i bought one that uses shop air from MSC. their ad said it held 5.5 gallons. when it came in it only held 5.5 litre. had to send it back. my liquid vac has a bad diaphram and cannot hold a vacuum so i'm looking for something right now.

can you tell me where you saw these 2 liquid extractors?

tks

From brakes to oil:

I got those images from http://tooldesk.com

No direct links. Search for mityvac.

This is not any sort of endorsement of this vendor, since I was just 'borrowing' pictures from them.
BTW, I noticed the pneumatic one has an 8.8 liter capacity.

There are a gazillion vendors for these things.
Harborfreight also carries some models on these.
They also have a 6.25 GALLON pneumatic extraction device for $130, but it looks like the actual 'fine print' capacity is 4.25 gallons:

Or if you're tired of hooking up special equipment, you can use this approach. I'll never go back.

Speedbleeders, I tried once, I did not like them.

I want to buy a brake bleeder for less than $500, but more than $200-300 that will do domestics and import cars including MB, BMW, VW/AUDI.

ANY new ideas

gsxr · #11 09-13-2003, 12:49 AM

I'm surprised nobody has mentioned the Speedi-Bleed pressure bleeder (which is NOT the same as Speed Bleeder). Using vacuum to pull fluid through is a bad idea as you almost always get air leakage around the bleeder screw nipples, and the resulting bubbles are a nuisance because you don't know if the lines are clear yet. MB dealers use a pressure bleeder. It works great, although when done you need to remove a little fluid from the reservoir with a turkey baster or something. Make sure you replace the rubber "buttons" on the m/c reservoir before starting or you could end up with a real mess if the old ones are cracked. I love mine, I'm annoyed that I used my MityVac for so many years - the Speedi-Bleed is much superior. You can still get the kit for German cars here for $40:

I still would recommend looking at the Motive Power Bleeder. Mine seems exceptionally well made. I don't see why it wouldn't last for hundreds of uses. $50 is a small investment -- so if it doesn't meet your expectations, you don't have much into it. I think you'll be pleasantly surprized.

The big advantage to the 'pull' (vacuum) method is that it fits any sort of car, truck, or equipment that you may need to bleed without reservoir adaptors and such.

My vacuum device has outlasted the ownership of so many disparate vehicles, that I find this to be an important consideration.

Any air that comes in around the bleeder valve is outside(and remains outside) the hydraulic system, so it is not really a problem.

This can make it difficult to distinquish between air that was in the system vs. air that came in around the bleeder.
A little silicone grease on the bleeder threads will prevent this.

gsxr · #14 09-15-2003, 10:48 AM

Some cars with ABS can NOT be bled with the vaccum method, and require pressure to bleed properly. I believe this applies to all Mercedes with ABS. There are valves in the system that require pressure to move fluid through them, vacuum won't do it. It does work on most older cars though. I used the vacuum method for years, but after trying the pressure method, I'll never go back. It's that much better. For you guys who like to make stuff instead of buy it, here's some DIY bleeder articles that simulate the Speedi-Bleed kit:

Bought a Vacula years ago and found it to be a PITA to use. I found another system made by Gravity. It was cheap and has worked well on all model cars that I have worked with so far.
