Motive Products Pressure Brake Bleeder Modification
« on: November 07, 2021, 07:40:42 PM »
The Motive Power 0100 European Power Brake Bleeder Kit is a basically good idea but is a PITA to use, Why? Here's the problem;

The pressure tank hose is provided with a male brass 1/4 NPT fitting that is intended to screw into a female brass 1/4 NPT fitting on the end of the hose connected to the fluid reservoir cap. Simple, right?
No, screwing the pieces together winds up the hoses since there is no provision for rotation- the plastic hoses are crimped on both ends.. Screwing the two hoses' pipe threads together first and then threading on the cap winds up the hoses. too. A simple modification will solve this problem. Here is how:

Thread an air hose fitting on the tank hose end. Seal the threads with Teflon tape.
Buy a replacement brake fluid reservoir cap or sacrifice your original cap.
Drill a 1/2" hole in the center of the cap with a step drill and thread in a 1/4 NPT fitting as shown in the photo. This will probably seal in a plastic cap but for added insurance against leaks I added some JB Weld epoxy around the threads inside and out.
Now you can screw on the cap, connect the push-on fittings and pressurize your master cylinder. No tangled hoses!
