I have seen videos of people using pressure bleeders that attach to brake fluid reservoir, I can't seem find them in europe

Is it possible to bleed alone with this type of vacuum bleeder? Or is this just a pressure leak testing pump and 2 people are needed to bleed the fluid?




Also found this,



Would this be similar to motive bleeder?

You can use that first type just fine; those are used on motorcycles, it just make take some time. The second apparatus looks like it would work if it has the correct cap to fit the BMW brake master cylinder reservoir. It looks like the pressure comes from the tire, where the hose supplying the pressure attaches to the Shrader valve on the wheel. You have to be careful though, because th max pressure you want to use to pressurize the brake master cylinder reservoir is only 18 - 20 PSI, where a tire is over 30 PSI.

Instead of those, just use the two-person pump method instead if you can't find a pressure bleeder. If you are good, you can do the pump method by yourself. If you have the proper catch bottle set up where the end of the tubing connected to the bleeder valve sits in brake fluid and doesn't allow air to get back into the brake caliper, you can use a boom handle to pump the brake pedal. The trick is to have the catch bottle above the height of the top of the brake caliper. And once pumped a few times wedge the broom handle against the door frame rubber seal to keep the pedal pressed down, then go close the bleeder valve.

I had no issues doing a fluid flush by myself with the kit below.

I currently use a pressure bleeder and it is GREAT, but if you say it's an issue getting that in Europe, then not an option, though I'm a bit surprised by that.

A few cars ago I used SpeedBleeders (http://www.speedbleeder.com/). This replaces the bleeder screw with one with an integral check valve. You turn it 1/4 turn like normal, but nothing happens until you press the brake pedal. So it's like the normal 2-person method, but you don't need the second person. It seemed to work pretty well, but does require replacement of the bleeder screws.

I had a really hard time using the bleeder in the first pic. I rented one from advanced Auto. Ended up just getting a buddy to help do it the old fashioned way.

Now, I was doing a full bleed and replacing all fluid, so that might have played a part. That fluid looked amazing in all corners when I was finished

I prefer this style system. It uses air pressure to create a vacuum that sucks through the bleeder instead of putting pressure in the reservoir. A self feeding tank sits inside the reservoir so it’s always topped off.

Who's kit is that? Looks nice.

The vacuum bleeder is by capri and the feeder bottle is by fit tools. Both on amazon, though lots of different companies with similar products out there.

I've had and used mightyvacs, compressor powered venturi setups like above and the motive pressure bleeding setup.

pressure bleeding wins, every time.
vacuum bleeding works, but there's some tricks. First of all, take the bleeder screws out completely. Otherwise you'll just suck air at the threads. Take it out, use the small tip ad jam it into the caliper directly. It will work mo betterer.
secondly, the hoses that come with the kits are too short to be practical. get some new vinyl hose.
A larger catch bottle also goes a long way. The small one sucks.

personally I've not touched any vacuum bleeding stuff since motive. I can do all four corners in like 30 minutes. it's amazeballs.

I used motive too last time just simple awesome.

i used the motive one as well...its $55 on ecs. i believe all the european brands use the same connector for the brake resevior so you should be able to use for other cars too

thus far it fits volvo, bmw and vw.

fromthe same euro kit cap.

motive lists european distributors.

I agree with the Motive unit, great device and procedure. The reason I asked about the vacuum setup is because my Hummer for some reason doesn't interface well with my Motive pressure bleeder. Yup, I have the GM cap and tried both thicknesses of the rubber sealing washer. I've followed the pressure bleeding proceed from All Data too. All I get is brake fluid all over the engine compartment and on my shop floor

IMO you can't bleed the clutch without a pressure bleeder. Vacuum doesn't work on the clutch hydraulics.

that brings the suck.

Mightyvac will get it done.
since it's a hummer it likely has some generic bleed screws.
speed bleeders work, you can find the common sizes in the help section at the parts store.

also super handy on trail rigs because you can bleed the brakes easily after trail fixes because you're dumb and tore a hardline off the axle....

don't ask, it was a brilliantly stupid one in a million thing that wiped the hardline off the top of the axle.

I used to have something like the Motive bleeder - but after about 15 years the seals all dried out. I ended up making my own simple one with just the connector to the resiviour hooked up directly to my air compressor. Just keep the PSI under 20 and it works just fine, it's even less messy to clean up and wastes less fluid.

this is a fair point.
I saw a DY where a guy made a pressure bleeder from a garden sprayer.

I deemed it not worth my time since I could buy one for $55 on amazon, but for someone where it's not available...

Yeah, I'm not sure why it doesn't work to pressure bleed the Hummer. I just need to resurrect my wife's calibrated right foot . She likes (I think) riding the lift

I have the Motiv bleeder with the aluminum reservoir cap.
Worked great to bleed the F3x brakes in my E90.

Using the vacuum style bleeder in the first picture, I was physically unable to get tubing to fit well enough around the bleeder nipple, so as soon as I pulled vacuum it was pulling air around the bleeder from atmosphere. It still worked well enough, but it was really hard to tell when I was 'done' bleeding because of all the extra bubbles. Because I was alone and I needed to get the car on the road, I ended up re-bleeding each caliper 3 or 4 times until the pedal didn't feel spongy (took a long time, wasted a lot of fluid), then re-bled using the 2-person method the next day when someone was available.

[nsjames]

that's why when you use a vacuum bleeder you really need to pull the bleed screw completely and use a narrow tipped adapter directly into the caliper.

If you do it right you can pull 25in of vacuum and it will hold for a long while.
