Pressure Bleeder

[jordankjcm]

I'm thinking about crafting a pressure bleeder for bleeding the brakes. I have all the parts with the exception of the cap that will screw into the master cylinder. I have the original style of MC cover with the male plug that screws into the top. Does anyone have a the size of the plug that will screw into the top, or have a suggestion as to what would work for the top adapter? It would have to have a tube run through it so the bleeder can pressurize the MC and fill with DOT3 fluid as well. I was thinking of some type of PVC or plastic plug. It doesn't have to handle much pressure (<15 lbs).

Thanks!

I have a Motive pressure bleeder, which is a simple pump up container with a pressure gauge. I just made a threaded adaptor for the fitting on top of the cover, and filled the pressure bleeder with some DOT 3 and was set. Bleeding the brakes was a piece of cake. I can go to the garage and dig it out if needed

The threaded adaptor fitting for the top of the master cylinder is what I need to fashion. What did you use for the adaptor?

Thanks!

I used a couple of pipe reducers (I think I started with 1/2 inch) until I got down to a nipple size that my bleeder (garden sprayer) hose would fit over (I think it was 1/8th inch brass pipe).
Just a heads-up:
I poured a half quart of fluid in the bleeder, pumped it up and opened the valve. Fluid level went down and after a couple of seconds I heard air hissing out of the bleeder.
Ready, fire, aim!
I then closed the vent petcock on the master cylinder, removed the three plugs in the top of the intake manifold and sucked out all the brake fluid with a turkey baster.
Drained the oil and happily saw no sign of brake fluid.
I replaced the oil, put the remaining half quart of fluid in the bleeder and proceded with the bleeding process.
I hope soemday the pain will wear off and I can have a chuckle when telling that story.
Good luck,
Dan

LOL!!! I would have done the same thing!

Dan, thanks for the tip...I never would have thought that the fluid would be pushed into the manifolds. I'll make sure I shut the vent petcock, so not to replicate your experience. Thank you for your tip and information!
