Brake Bleed

I like the simplicity of the idea, but you mention an empty system. For most of us, that's rarely the case. We might be changing an existing part in an existing system. But this could still work. Firstly, take an existing system with fluid in the lines. Connect your system, open all the bleeders (connect some plastic hose and "pots" to each one). Power it up, open the valve and flush all fluid from all lines, emptying the system.

Then repeat the process as you've described in your video to refill and bleed the system.

Thoughts ?

You'd blow the line right off the bleeders..... and then blow fluid everywhere.


Mark doesn't go into enough detail about where he took the vacuum from --- and put the pressure to. Is the vacuum at ONE caliper - farthest away from the Master cylinder or where?? If so - how do the other calipers get fluid?

I like the idea but was left totally not understanding the detail of the process.....

yeah good point Greg, I think it could be possible though with less pressure

All the OEs do millions of cars this way every year. That is why I built my systems. The GM Parts are disgned to do it this way.

I was at the Camaro assembly plant for months and watched the systems work.

I'm not saying this is for everyone but it worked for me.

I totally understand you wouldn't do anything that wouldn't work ----- What the video doesn't show is many details..

Sorry Greg I revised my original post with more detail. See above.

It looks like the lower gauge on the manifold is where the vacuum is pulled from and the pressure is applied from the top of his reservoir, which would work just fine....if all the ports in the system are wide open. Obviously not the bleeders.

Need more details and information....please.
