Brakes Front brakes heating up, pressurizing fluid, pedal stays up

These pins act as pistons too correct? They are forced in and the air pressure from the nipple allows it to slide back out. Maybe these pins are just do dry. I'll test greasing these pins up and see how they act. I'll order some new pins as well to get the process started.

Ya, they dont look real straight to me as I was looking at them... I was like surely not. Heh.

Make sure they're straight.

For those who want to see what Im working on if peaking in on the thread....

Ya it's all new hardware, which I know means nothing. heh. From the naked eye they do not seem 'bent' but my eyes are saying something is not right. I'll roll them on a flat surface tomorrow to see what I get. I went ahead and ordered new pins and grease and pick them up Monday. Will do the drivers side as well just to address any and all.

OK, tried different things and still same result. I talked to a few other people and also @Noobz347 about my tests and we think for sure that passenger side caliper is just bad.

1. I put the new pins in well greased.
2. Cranked the car, applies brakes. Turned off car.
3. Right rotor was seized, could not turn by hand.
4. Release the bleeder valve to start a test and no fluid came out.
5. Removed the new pins from the caliper. Still could not turn the rotor.
6. Removed the caliper to take off the J&M brake line. No fluid came out of it from disconnect on caliper side.
7. Broke the fitting lose at the frame metal line to the J&M line and the fluid flowed out of the JM line as expected till emptied.
8. Put a tube on the metal line and applied brake pumps several time to see the fluid come out clear and no trash.
9. I could push the caliper piston in by hand once I had disconnected the main brake line.

So thoughts are bad caliper. I would also like to replace the master cylinder to a new style, as its the factory old style. The master was a reman from Oreillys a few years back (no part number to provide) and the calipers were just a reman kit from LMR, they currently show these out of stock on their site.

@Mustang5L5 suggestions?

Quality source for reman calipers and a modern style master that fits current fittings etc? I do not really want to spend the coin on a Brembo front Big Brake kit for 15" wheels... $1700.

I also have an 89 LX proportioning valve here I took off my BTC project that could get swapped in as well, so maybe a new master cylinder, prop valve and caliper.

I am planning for rear discs... but not a tomorrow thing. Sourcing parts might be hard right now, a lot of suppliers are struggling with Covid demands due to all of us sitting at home wrenching.

But I can entertain the idea if you guys can steer me the right direction. Change it all over, I have flare tools too and could convert some line ends as well as needed.

Ill test the brake line in the morning, it's a brake line that J&M made me. He made me these lines as a one off on request and said the crimper could have not been set right.
