Pressure Brake Bleeder - another way ...
Buddy Richard ( '86.5 5-sp) & I have debated many silly ways to design a DIY pressure brake bleeder - but this one works like a charm! With some additional fittings, it will also double as a coolant system pressure tester ...
At the heart of this new toy is a small precision regulator with a pressure gauge: Connected to shop air, air pressure is stepped down to a spare brake fluid reservoir cap using two swiveling ( Legris) fittings and a piece of pneumatic tubing.
Setting air at 8 psi, and spinning the cap off to occasionally top up with brake fluid - brake & clutch bleeding was a solo operator breeze. No more a threat to domestic bliss in trying to coordinate "pump, pump - hold ! No, No! ... " well, you said to .."
).
This first version passed with flying colours this afternoon: Version II will have two lines tapped into one of those bottles of brake fluid shown - and air will transfer the fluid directly to the reservoir when the container is placed just downstream of the regulator. Plus, as mentioned, when tapped into a coolant line, it becomes a system tester. No patent applied for
- try it, you may like it.

Garth...........very innovative, well done.
Had a m/cycle racing buddy convert a Coleman lamp ( the ones you pump up to create pressure) that did a similar job, clean, efficient and zero stress on the SO relationship.
Still, with the Motive bleeder on sale for $39 @ 928 specialists, hard to beat.

Been using that one for years, patent is probably out of the question. (ask MrMerlin what happens when you fill the resivor with ATE blue and put the shop air hose on it without bringing the pressure down enough. 40psi worth of blue brake fluid all over the bay, blew the resivor right off the master cylinder!)

". I'm sure you understood the comment as fecious humour 
Having been a 'lifer' at pumping the brake pedal - never again: now to make a monster adapter for the Chev 4x4 fluid cover ...

Yes, that is a concern - and why a second fine adjust regulator is a reasonable approach: My concern was blowing off the infamous 'blue hose' to the clutch MC - replacing that could wreck a guys day ....

I made a smaller one for doing my tranny fluid. Drop the weighted end of the tube in the resivour, open the air valve and the fluid goes up and in. Ive got a converter seal with a slow leak, so i get under there more often than i like ...this makes the job much easier.
