Bleeding Brakes -- My Way

JCS4640 on Fri September 08, 2006 3:11 PM User is offlineView users profile

Yesterday I had to put new Calipers on the rear of my '76 Vett, and of course, when it came time to do the bleeding, there was no help to be had. I have a hand vacuum pump for doing bleeding and (it is useless so I threw away). I gave it some thought and I noticed that I had about a half dozen empty R-22 bottles and I had a brainstorm!!!!!!!!!!! I made the bottle into a vacuum bottle but you all know the valves on these bottles are a one way flow only. I cut the valve off my main tank, drilled and tapped the hole on top of the tank to 1/4 pipe, installed a brass fitting I found in the garage which now has a low side gauge on it, and I put a Shrader valve on one side, and then I cut the valve out of the other tank with about a 2" diameter of the tank left on the valve so I could attach it to my other tank. On this valve all I did was drill a 1/8" hole from the bottom side up into some kind of plastic inside which made my valve two-way - about an hour and a half later I was bleeding the brakes and this thing really does the job! I'll send pictures if I can figure it out!

I like that idea did you use a mig to weld in the fitting or braze it? and if so what kind of solder did you use? and did the gauge screw right into the existing valve hole?, hey lots of questions but I need to make me an air tank to blow out condensate lines with and I like that idea, the gauge is a little big, might get broke off in the back of my truck but I could buy me a smaller gauge.

Don't take life seriously... Its not permanent.

No the gauge does not fit in the hole,you can drill and tap for 1/4 pipe,My gauge is hi because of the fitting i used but you can have it lower no problem to do. I used stick solder and stainless acid. O there is a pop off valve on top about the size of a nickel,take it of and weld i/8 hole

Seem to have that same problem myself, though with my second hand vacuum pump, paid a bit more and got one that was rebuildable with a relatively inexpensive O ring kit. Spent twice the time making stuff so I could drop my TH400 transmission myself then it took just to remove the transmission, yeah, was advised to either buy or rent a jack, couldn't find anything that would go low enough and high enough and wasted more time looking than building what I have.

To me, using the vacuum system to bleed brakes is a good start, but always seem to get more air out with someone pumping the pedal, that was one job my wife could help me with, but I have to be careful not to yell, LOL, she can hear me. Ha, step hard on the pedal, honey and hold it until I tell you to release it, count to ten and step on it again. Are we done? No, honey, we have three more wheels to go.

Son is coming over this morning to help me put the transmission in, just want someone on top to start the bell housing to engine bolts so I can use both hands in the bottom to guide in the transmission.

I just punched a couple holes in a Mason jar lid and soldered in a couple 1/4" brass tubes for a catcher, couldn't you just as well hooked up your vacuum pump to that? But would add a valve in series with the pump for fast control, you may have found your master cylinder in that Mason jar with that kind of vacuum.

Now let's see if we can figure out how to mount 4 by 12 foot sheets of drywall to a ceiling, by yourself.

When i was 45 I hung about 40 sheets of 4/12/-5/8 rock alone off 6ft. ladder, I did set 2 or 3 nails in the sheet first

I too, tried all the brake bleeding gizmos and gadgets with varying degrees of success (usually minimal). I finally sprang for a real pressure bleeder and never plan to go back to that other stuff. It is quick, easy, and does it right. The added bonus...I can do it myself and avoid the spilled fluid and the inevitable shouting matches while I had my better half pushing the pedal.

The only downside, other than the cash outlay, is you need an adaptor for each type of master cylinder.
