Anybody use one of these? Does it work well?
Thanks in advance.

yes I use it on my 911 and Dodge 2500, each vehicle takes a different cap for the master cylinder.. dont have to bother momma to pump em:}
I made a pressure brake bleeder out of a half-gallon bug sprayer from ACE hardware. For the cap on the reservoir I just bought a new cap from a VW parts place (happens to be the same as a Volvo if you wish to upgrade).
I can send you the plans, if you wish (the "user Manual") is attached.
I've modified mine with a 1/8" ID "Quik-Connect" fitting that allows the cap to rotate freely AND I can quickly change from the Speedstah cap to a different one on our other cars. "Constant Product Improvement" - just like when I was still working!
I should have known Gordon would have a less expensive very effective alternative!
Thanks!!
Wow Gordon great write up, post the plans cool build

I dig this. I need to bleed my brakes soon. I've always had the wifey help me in the past. I'll start looking for the parts. Thank you for the DIY write up Gordon!
The original plans I used (from a BMW site) are kaput, so look at this one, with some caveats:

Here's the sprayer I used. 2-quart should be fine for a Speedster/Spyder system:
Caveats: You do not need a pressure gauge. What are you, NASA? Give it 3 or 5 pumps (tops) and you're good to go.
Get a real VW brake fluid reservoir cap (or a cap for whatever reservoir you are using) and modify THAT. Nothing beats the real thing. Remember to add an o-ring or rubber washer inside of the cap to seal it if it doesn't come with one. From the top (inside) of the cap, figure out the depth that the fluid is when at the "full" line. Add a length of copper tubing from the cap to that depth and when you're done bleeding and drain the system, THAT will be the depth remaining in the tank (see the user manual).
You do not need a tank bleed valve, but if it comes with one, that's a bonus. Instead, just unscrew the pump handle enough to let it release pressure. Again, we're not talking a lot of pressure here - maybe 4 - 5 pounds max - to do whatever bleeding you need to do and you will not have brake fluid just spewing out when purging the tank - not gonna happen.
The water-cooled division of Five Cent Racing stole my version with the quick disconnects so my remaining one just uses the the original sprayer wand valve (which has a locking on feature) and the hoses that connect to that. Unscrew the cap end, screw the cap onto the reservoir then screw the hose onto the wand valve and let 'er rip!
Here is another good video showing how to make one:
https://www.youtube.com/watch?v=GX04sMcMweg
Remember to gently pump a little fluid through the system first to get it to the cap, then screw on the cap and pressurize the system. It will hold 2 quarts of fluid, enough to easily bleed the entire system whether Speedster or Spyder (hydraulic clutch, too).
I never save the remaining brake fluid - it absorbs water too quickly so I just discard it. You can try bleeding with just a quart of fluid - I have and for one or two wheels (maybe even 3 or 4 if you're efficient) had no trouble. You cannot introduce air into the brake system with this bleeder due to the design of the cap tube.
I had all the stuff beyond the sprayer kicking around the shop, but even if you buy new parts to do this, you should come in somewhere under @$25 bucks, or about $100 less than commercial versions.
Happy DIY-ing!
Gordon could you not simply top up the fluid at the end to the fill line if your off with the height of your fill tube cap combo?
"Gordon could you not simply top up the fluid at the end to the fill line if your off with the height of your fill tube cap combo?"
Sure, but 99% of the time that is unnecessary - when you let it drain back into the sprayer after you're done bleeding everything, the fluid remaining in the reservoir should be right at the fill line if you've set the length of the tube under the cap correctly. If not.......Top it off.
I've tried commercial vacuum bleeders and pressure bleeders. I even have a spare MC cap with a Schrader valve threaded in the top. I use that for initial bleeding.
But I have never gotten as solid a pedal as I do when you do a good hard and heavy 3 pump-and-hold. Repeat about 6 times. It seems to drive the tiniest air bubbles out and give you a repeatable, high, and solid pedal. No hot fluid(air) fade.
I found the reservoir mounted position sits at a slight angle the back chamber (closest to the fire wall) went dry before the front chamber-was a pain in the butt. Watch out for that.
Re; Brake Bleeding:
If you use that unit @Gordon Nichols that you created what ever you use of brake fluid and what ever is left will be contaminated by the air and moisture so you have to throw out the rest for sure.
I am thinking of building one over the winter and I guess I need a cap are they all the same size? Not sure what IM is using as a stock part.
Yes, brake fluid absorbs water like a sponge so I made my pressure bleeder in a 2-quart size so it’ll work with a single quart of juice so I’m not wasting a lot when I use it. Been a good approach thus far.
All of the “VW” style caps are about the same and the same as many Volvo tank caps, too. Probably the best thing to do for an IM, though, is either get another one from IM or find out what it is, from them, and get one locally to insure that it’ll fit your tank cap threads.
Hey, while we're on a thread of DIY projects, my neighbor recently threw out a worn-out document shredder for the trash truck (it had chewed up too many old credit cards, I guess). I grabbed it and removed the drive motor from it and then put the shredder remains back for the trash.
The drive motor is about the size of a hand ball and runs on 110 volts AC so I pulled it apart, removed the armature and bearings and turned it into a magnetizer/demagnetizer.
You may have seen my first one, made from a removed oil burner blower motor, but that one admittedly has a YUGE! coil and is vast overkill for a shop magnetizer that gets used mostly for screw-drivers (but Tim Allen on "Tool Time" would absolutely LOVE IT!)
THIS one is much smaller, and while it can't turn a regular spark plug socket into a magnetized spark plug socket, it is just perfect for zapping screw-drivers and other iron-based tools and doesn't heat up while in use like it's big brother.
So, I give you the original "Ultra-Magnetron 10,000" and it's new, soon-to-be-a-Christmas-gift little brother, the "Magnetron 1,500 Lite".
Do not be fooled by the "Lunch-Time Salad Container" look - This is a serious piece of shop equipment designed and built to last for generations of use, assuming we're still allowed to have small hand tools in a few more generations. Fully fused and thermally-protected (as the original motor was) for operator safety, "The Magnetron 1,500 Lite" is the perfect tool for instantly magnetizing and demagnetizing any of your shop screw-drivers or small pliers - in fact, ANY small ferrous tool in your shop, with a simple pulse of the power button!
(Note: This model might not have enough poop to magnetize sockets larger than 1/8" and it shouldn't screw up your mechanical Rolex Oyster, but we haven't yet finished environmental testing so, in the meantime, don't wear a mechanical watch within three feet of these devices when in use - Caveat Emptor).
Never again will you have to hold a screw on the end of a non-magnetized screw-driver with one hand while trying to turn the tool with the other as the tool itself will hold the screw fast all by itself. When you're done with your job you have the option of leaving the tool magnetized or returning it to a non-magnetized state with the push of the "Mag/DeMag" button. The perfect multi-purpose tool!
Another quality shop product from the Christmas Elf at:
Five Cent Racing ≡ Air-Cooled Division!
Remember, these Magnetron tools are NOT sold in stores.
(In fact, they're not sold anywhere.)
But one just might show up at the Carlisle Raffle (if I find another motor to cannibalize).
Emailed IM ... Interesting other method, but I would be afraid to take too much out of the reservoir and introduce air and also run out of fluid... Maybe with two people.

Here is another product that is interesting using tire pressure ... tire bleeder
How many feet away do we have to stand ... from your magnetron?
It depends - Are you wearing a Pacemaker?
No, just wondering I could of used you creation the other day I had to settle for a few strong magnets stuck on the screwdriver which magnetized the blade of the screwdriver
Oh.
Well, with the Magnetron you can just stand there like you're using a teapot. Insert the tool in the black tube, hit the button for a second (short pulse) or so and remove the newly magnetized tool to use it.
To de-magnetize the same tool, simply insert it into the Magnetron tube, push and hold the button while removing the tool, then release the button and the tool is de-magnetized.
Thank you, William Gilbert.
Well you can make a remote button just like an x - ray tech in the other room . Just kidding
