Default Brake bleeder

Who has the Motive Bleeder and uses it on their '67 or dual master cylinder? Do you have a special adapter for the dual master? Picture of adapter or source too purchase an one? Dennis

JohnZ published pics a few years back. He re-issues them periodically. I believe he uses the stock adapter/cover for a dual MC from MOTIVE and then uses one or two large c-clamps and a small section of unistrut or square box channel to secure the adapter to the master cylinder.

I've been bleeding brakes successfully without power bleeders for the past 35 years or so. I bench bleed the master, and gravity bleed at the wheels. Simple, easy, effective. JMHO....

I have the same set up as pictured. I am also a proponent of the old fashioned way. That's how I did my 67 when I replaced an aftermarket master cylinder with one of the new correct reproductions.

Buy recently a friend and his helper tried numerous times to bleed a 67. Not sure what or if anything they were doing wrong. But I took my Motive kit and he and got the brakes bled in less than an hour.

They do work, but probably not necessary in most occasions. The one thing I like is that I can bleed the brakes with it by myself.

I have a Mity Vac, it works well, but I like the idea of having fresh fluid entering the brake system from the top down. Dennis

With the Mity Vac I find that I get air leakage past the threads on the bleeder screw(s). Therefore I never know then all the air has been removed from the system. This requires that I use a second person to work the brake pedal for the final flush. But the Mity Vac helps out a bit...........especially is you use a pint/quart Mason jar as a vacuum reservoir. This extra vacuum capacity really pulls the brake fluid thru the system when you first open the bleeder screw(s). The Mity Vac I have has adapters to use this jar in the system.

I could probably use the speed bleeders (which have a seal on these threads) if I really wanted to do it all myself......or use the Motive Bleeder. Like so many above, I never really needed any special tools to do this job over the last 50 years. This includes using silicone fluid for the last 20 years.

But I do like the Motive Bleeder, and might just buy one the next time this job comes up. You can never have enough garage tools.

Powershift, the air leakage has always been a concern of mine. Dennis

Gravity bleeding is just fine.

Just let the fluid run out until you get clear fluid.

If you get really nasty fluid you might consider doing a denatured alcohol flush.

And gravity bleeding replaces the fluid from the top down, too. That's how gravity works!

It takes me less time to do the actual bleeding than it does to jack the car up and remove the 4 wheels.

I use kit supplied adaptor along with a 1/2" aluminum plate on that and my large C-clamp to hold it all together. Sorta like what oldpainter's picture shows

I've been using the pressure bleed method since I started working at Clyde's Texaco in 1961 (he made his own).
