But I'm curious as to how it attaches to the MC and forms an airtight seal. Does it work if you have a dual MC? After you have bled all four, is the MC full of fluid? Which model works the best ?
Thanks

It uses air from your compressor to create a vacuum in a canister you attach to your bleeders at each wheel cylinder. It comes with a fill bottle for the MC. I used it on my other truck and it worked good, but not on my ‘52 1/2 ton so I don’t know if the fill bottle will work. It will drain the MC in a hurry so be sure to fill after each wheel.

They have several adapters that connect to various master cylinders. For the dual MC, there is a flat plate adapter that covers both chambers. If you have need for a dual MC adapter, be sure to get the one made out of aluminium. I have found that the fiberglass/plastic ones sometimes flex and leak under pressure and require additional clamping.

I made an adapter out of a spare M/C cap. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Check the Motive website. They make/sell "caps" for most types/brands of master cylinders. Determine what you need, and then order from Motive or other from other vendors of their products. | | | | | Joined: Dec 2002 Posts: 3,439 Moderator - The Electrical Bay | | Moderator - The Electrical Bay Joined: Dec 2002 Posts: 3,439 | I use a plastic bottle with a hole in the cap, run a piece of clear tubing that fits the bleeder valve, and presto, a one man brake bleeder system.
Another quality post.
