Homemade Motive type power bleeder for $14
Went to Walmart and bought a sprayer - $9 inc tax
then to Ace Hardware and bought a fitting- $3 inc tax
then to Autozone,guy sold me a used top - $2 cash no tax
Came home drilled a hole ,did some soldering,cut the gasket and here it is, a $14 power bleeder that works in about an hour and a half.
First pic is for show,you can't use just the bales , you need large clamps,2nd pic shows how you must clamp it down. Just thought I would share.
Here is a link to the sprayer. http://www.walmart.com/ip/RL-Flo-Mas...rayer/13376324
This pic shows the inside. I also soldered the vents closed and flattened the top so the clamps had a place to sit.
For those concerned about introducing air into the fluid here are couple solutions , the top pump is a shorter one I found for mine and I can put 2qts in mine without the pump touching the fluid,you could shorten a pump,the bottom pump is the one that came with the bottle with a plastic bag and straw to direct the air up and out of the fluid.
( I started to demonstrate with one of my Magnum's instead of that plastic bag but I'm hoping to get lucky tonight and I might need all of them.)

Thank you , this bleeding process seems to be the most popular.
This $14 unit ,if used carefully should suffice for most guys that only have 1 vette.
After bleeding their car they can pour out the brake fluid ,put some RoundUp in and go kill their weeds.

I made something similar, but used a flat aluminum plate for the top. It worked pretty well, but I managed to make a mess when I unhooked it.
I decided at that point that using the sprayer for pressure only, and refilling the master cylinder with brake fluid as needed was a much cleaner process. YMMV

reminds of the time i went to kill all the weeds with my pressure sprayer and spent 10 mins walking around the yard squirting the weed b gon on the weeds only to find out when i was done that the weed killer was still in the measuring cup on the front porch.....i forgot to add it to the sprayer....so what i had just done was selectively water only the weeds in the yard.....

I do use a Motive pressure bleeder and modified the clamming system that covers the Master Cylinder which works but is not exactly easy to hook up...
BUT looking at the pictures of how you simply modified a standard cap for the master cylinder I know will be duplicating this cap in the next few days...
BTW,, I own 6 Corvettes and 3 of them are C3's and I have to bleed the brakes on each of the three every spring ...
my C2 which has the same design brakes rarely needs any attention.. The C4 and C5 are just a regular maintenance type of deal...
Thanks for the GREAT IDEA...

This tube will keep the level below where the top meets the master cyl.
Then if you release your air pressure from the Motive tank you will have almost no fluid spilling out.
In the case of my $14 unit you would have very carefully loosen the large pump handle or install a pressure relief valve like the Motive has.
When I get a min I'll post a pic of my very old "fancy" unit with the release valve and pressure gauge.

As promised is my fancy dancy unit , it has a pressure bleed-off valve and a gauge. Wow ,this one is worth maybe $6 more.
The top is 3/8 steel from an old Ammco brake bleeder and I extended the inlet tube and sealed it so no fluid gets behind the rubber gasket. The original master top (above)has an advantage over the flat plate style in that if it would spring a leak the lip around it would deflect the fluid down rather than straight out.
The larger hose is just a safety around the smaller inner hose in case it would spring a leak ,the fluid would run out the ends,analitus.

but as to the bleeder, just drill a couple of 1/8 holes in the top, and secure with the stock clamps, and take your air jet with the holes in the sides of the discharge...the one typically used for blowing crap off, and hold close enough to the holes, and the pressure will divide itself out....too close maybe blows fluid out the gasket, but you WILL blast those lines full of fluid....
it's how I fixed my '72 here after years of fighting it....
there are several ASSpects of these brake systems that need attention not a pretty tschituation.....

It was hell bledding my new brakes. I rigged something up to put pressure on the master cylinder. It worked great pushing the fluid. Nothing else worked.

Maybe I'm missing something here. Isn't the "mess" problem an issue of releasing the pressure gently without disturbing the master cylinder? I know that my garden pressure sprayer has a release button on the side of the canister. Wouldn't that eliminate the mess issue?

If I'm not seeing things...looks like Roger has some sort of needle valve on the side of his unite.Muddy

I have not used the unit I bought.....may be returning it in favor of the homemade unit !
What is it with C3 brakes ? Why won't simply pumping the pedal with a wrench on the zerk do it ?
