Thought I’d share with the group how to make your own brake pressure bleeder kit. I’m in the process of building my own,looks simple and easy.

[quote=”twiggy02919″ post=32706]Very nice, thanks. If you build yours please let us know how it works.[/quote]
You obviously didn’t watch his videos of how it worked.

Yes i did watch the vídeos. I think you misunderstood me because I was looking for first hand confirmation on success from someone in the ETCG community.
Twiggy I built it. Pumped it up to 10psi it held pressure never went down,so I assume it would work. If the tank was cleaned out it could be used as a cooling pressure tester would just have to buy a separate cap for my expansion tank.
Occasionally I think about doing this. But then what goes through my mind is the question as to whether the cap on the MC is the same size with all vehicles. Is it?
If they are different sizes, you would need a set of adapter caps to make the pressure device fit on top. By the time you make a whole set of caps, you could have bled the brakes normally with a friend pumping.
I do have a vacuum bleeding device, but it seems to regularly find a leak at the hose connection, so I rarely use it.
Thank you for your feedback. I have been wanting to build one for a while. It might be a little while longer as I’ve been working 70+ hours per week. Please let me know when you use it on your car, Id like to know how well it worked out over all.
Twiggy I used it last week and it worked great you just have to make sure everything is air tight. Also don’t go over 20psi I’ve been told to much pressure will blow out your brake seals
spelunkerd I bought a separate cap that works for my grand am. I only use it for one car and its easier for me and quicker by myself.

Unfortunately…they are. I have a ‘professional’ unit and had to buy a drawer full of adapters only to find sometimes I still don’t have the right one to do the job :angry:
As for using the vacuum bleeder, I too have found they seem to show bubbles in the fluid being pulled out of the caliper/cylinder, but what’s really happening is it’s sucking air down through the bleeder’s threads. That doesn’t mean air is getting in the system, just a bit annoying to gauge if it’s air in the system or not. Applying dab of grease or anti-seize on the treads helps.
Those were my thoughts too, John. Thanks for letting us know about that difficulty with cap size — its another reason why (for my amateur use) it’s not worth my time to get that kit. Too bad, I really like the theory of positive pressure bleeding. Yes, I understand it’s mostly an annoyance with an air leak at the bleeder screw, and I’ll try your idea to use a dab of grease or antiseize.
Duane at realfixesrealfast invented a ‘pedalpusher’ that uses compressed air for a one-man bleed. And Eric recently demonstrated a cool way to do this with a combination of gravity feed and a preprimed drain bottle. I think I’ll try his method next time.
great find with the video! i personally like the idea of bleeding the brakes with an extra person to press/release the brake pedal.
I was looking at a pressure tank made by Motive because they sell any type of adapter to fit your application and the price is reasonable compared to making one.
I used an oil can type bleeder I got online and it really worked well to push new fluid through my ABS module. I was pushing the fluid in reverse and omg the fluid was orange, captured in a container at the master cylinder connections with clear tubing.
