Motive Products Power Bleeder for a C1

[Christopher R.]

Has anybody bought a Motive Products Power Bleeder lately? They list a new one (0102) that might bolt on to the C1 master cylinder. But the catalog is contradictory, and I'm confused. I know they have the adapters that cover the master cylinder fill. I want one that bolts right into that hole.

Chris,
I bought the Motive Power Bleeder Pro, #0250 Model - the one with a set of 3 adapters "to fit European, Asian, and American cars". None of the adapters I got with it fit the stock C-1 master cylinder (...022). So, I took a chunk of aluminum and made one on my lathe. When I got all done it worked well, but it didn't work right out of the box.

The master cylinder adapters are the "weak point" of the Motive Products unit. Otherwise, it's a great system. However, as Dave mentioned, you can fabricate a master cylinder adapter or, in some cases, modify one of the Motive Products-supplied adapters to improve its utility. For a C1, I would think that the best adapter could be rather easily made from an old master cylinder cap. Just drill and tap it for an appropriate size nipple and install the nipple----presto, a perfect master cylinder adapter for use with the bleeder. I wish it were that easy for other Corvette master cylinders.

Why not do a manual bench bleed before

installing? Just install old metal line on output and run back into the master cylinder. Fill with fluid and depress the cylinder. This should bleed the air out of the master cylinder prior to installation. Haven't used this process in a long time, but it used to work. Good luck, Gary....

I don't see the need for this thing. I get my wife or daughter to push the pedal on command (the only time I get to do that) and operate the bleeder screws with a hose into a bottle. Takes no time, really, new from scratch or just a flush. Just keep MC full.

That's the beauty of the Motive power bleeder - you don't have to keep checking the master cylinder. Pump it up, take one trip around the car with the bleeder bottle, and you're done.

we made our pressure bleeder from a pump

up garden sprayer filled with silica gel to remove the moisture from the air coming from the garden sprayer. fill the master cylinder with fluid and connect the output from the sprayer to a modified MC cap and use the sprayer pressure to push the fluid thru the system. you can also use dry nitrogen for pressure. we started to use that after we started to use the dry nitrogen to fill the tires on the race car.
