Brake Bleeder

[CA Victoria]

FWIW:
While the power (pressure) brake bleeder is not a new revelation, the adapter I discovered was new to me and may be of interest to other home mechanics who are not familiar with these relatively inexpensive products.
The Motive brake bleeder I bought came with several adapters for a dual MC or single MC that clamps on. Since I bought it Motive introduced a CNC machined aluminum cap that screws into MC body. It makes the job much more pleasant with the thread in adapter.
Another positive feature is to be able to pressure check the connections and not over tighten but stop at a point when the seal is made.

A couple comments.

Using a "garden sprayer" for bleeding brakes in not the best tool because you're pressurizing air into the fluid. Best to spend the money and use a pressurized brake bladder designed for brake fluid, keeping the fluid as pure as possible.



You need to create MUCH higher system pressure for proper leak detection than what pressurizing the fluid reservoir can provide. Perform an initial system bleed to allow some pressure build, then "stand" on the pedal to develop the needed hundreds of fluid PSI.

This is all i have ever used for the last 30 plus years ,easy simple cheap one man never fail system.

While I’m not an engineer I do not agree with the statement made on injecting air into the fluid.
The Motive system works well for the home shop mechanics represented here. After using this one a couple dozen times it has successfully completed many bleeding operations. After testing at the specified pressure and working the brake system in place I do not have any puddles on the floor. GEFM!
IMO I cannot justify $1275 if the $100 option works.
I love the screw in cap option. They also make a quick change coupling for swapping adapters that I have not installed yet.

Likewise. I have used and made many from garden sprayer’s for our race teams over the years. Never an issue. The only way to bleed brakes. As far as this pressurizing air into the fluid this statement is garbage. This has also been confirmed as false by our engineering team. Cheers

Please explain definition of GEFM. I'm old. I get the IMO just fine.

Lol, me neither Lawson, I made it up.......GEFM, good enough for me
