Default Re: Bleeding brakes-pedal pressure problem. Could use some advice/suggestions

Don't despair, we'll get it fixed.

The first thing you should do today is unscrew the brake lines from the master cylinder. Then poke gently into the center of the MC fittings. If you have RPVs, you'll feel resistance right away. If a paperclip or better, the blunt end of a drill bit slides way in, you have no RPVs.

Regarding the inline RPVs, the red 10psi ones, can be installed in the closest hard lines to the MC like I have done on my '32. There is absolutely NO reason that they have to be screwed directly into the MC ports.

Here is the my rear RPV circled in a blue oval.



.. and here is the one for the front brakes




Also note that you can have RPVs in the MC and also in the rigid brake tubing too. Make sure the flow arrows on the added RPVs are orientated toward the brakes.
