I have a mid 80's parts car that I'm fairly sure still has the pv in it. I can send it to you if you want to experiment.

Sure I will take it if you can get it to me. I will start taking this one off and see if something jumps out and attempt to fix it as well.

@Mustang5L5 , Im tearing all this down and since going this far, Im gonna replace the master cylinder again, its all rusted up and messing with my head anyway from a clean up the engine bay standpoint, so which brand you like for that? I know they mostly same but whose? I'll then coat it in clear paint to stop the surface rust.

Less that 10 miles on this MC.

I'd probably go with a Reybestos unit. It's what I've run on my car and I've had no issues.

I'd swap that MC out too as well. That's just....wow.

My building was not insulated at the time of install on the MC I think... and had condensation issues in the barn.

It is now foam insulated and HVAC so Im all nice and cozy in here now.

Heh

Any particular bleeding kits you guys like? Buying the MC is the easy part, that bench bleed is a killer!

I am beginning to suspect that your booster is bad or that the spring return in the MC is bad and is only acting up when it gets 'mashed' into position.

I doubt the booster would effect just one caliper, I betting on junk in that prop valve.
Stranger things have happend though.

PV is off. I believe the rear and nearest ports are for the front brakes. I'll read up above about inspecting and rebuilding. I have also attached a picture of the booster... it's had better days eh?

Might be a good time to see if anything silly happens with the booster when you run the engine.

Hmm...did you have a leak? That booster looks like it's been seeing brake fluid.

If brake fluid seeps inside the booster, it can degrade the rubber and cause it to fail over time.

This car sat up for so long, that all happened prior to me addressing any brake issues. Guess could do a new booster too no?

Started on the PV disassembly.
