I am replacing my stock block and aftermarket prop valve with this combination doodad. Pretty slick little bugger. Matches up to stock lines pretty well. Only have to rebend the line going to the rear (bottom mount on stock block, side mount on this one). Anyway...

See that brake light switch there on top? Yeah.. under that is a small hole that allows brake pressure to trigger the light. As I dont need the switch and removing it makes installation of the inlet lines much easier, I am removing it. I have a plug for it. It originally sealed with teflon tape, I will do the same. Only one problem... can you name it?

Yep... I have no idea how to bleed the air that will be trapped under that plug. Do I need to? I gotta think I do... that would be a pretty ugly air bubble if I didnt.

Any ideas? I am thinking about leaving the plug loose and having the wife pump the pedal... when I get brake fluid seeping up, I seal it down. Not sure that method will get all the air out though.

Thoughts? Comments? Questions? Venereal diseases?

How about bleeding the brakes with the item not bolted to the fender? Bend it down so that the air has to get into one of the used brake lines, then bleed brakes. Once done, bend it back into place and bolt it down.

You lost me... this port doesnt have a brake line attached to it.

I inadvertently tried my own idea. I had Jen help me bench bleed the MC in-car. That went very well. Bubbles... bubbles... bubbles... no bubbles. I then quickly hooked up the lines from the MC to the block. As predicted, it gravity fed brake fluid through the lines and seeped out that port where I had the plug barely started. Oops... and yay!

I do have a notehr question. I have these brass junctions in 2 places on my car. Basically female/female adapters that join up brake lines. They are original... think they need replaced? Or only if they are leaking?

If it ain't broke, don't fix it!
