73 Headlights
okay headlight warriors. I rebuilt one of my actuators and the other one works fine. They close perfect and flush with car. When I turn them on and they rise, one is about a quarter inch lower than the other. I can even push up to lock it in place and its still a quarter lower than being flush with the opening. Looking at the driver side light from underneath, I notice on the right side a flat head screw that is on some sort of arm that hits the headlight frame when I push the whole headlight assembly up to where it needs to be. Is this screw my problem? Seems if I were to turn that screw inward enough it would allow the light to go farther up and be flush as is should when fully open. As of today I could not budge that screw even being soaked in some blaster. And its a pain in the *** to get to. Any ideas?

To get at that bolt, it's a fairly simple process.
Remove the four headlight bezel screws (1 on each side, 1 each top and bottom in the center). Pay attention to the threads. If they're the original screws in their original holes, you'll see different that they're different. Don't mix them up.
Use masking tape to cover the edges of the headlight opening on the front panel so you don't scratch any paint when removing the bezel. In your case, I hate to say it, but you're at a bit of a disadvantage since your headlight sits a bit lower, which will make it a little more challenging to remove the bezel from the headlight assembly. The further up the assembly is, the easier it is to remove the bezel. In any event, when you use masking tape, there's no need to use any that has the most aggressive adhesive - you don't want to pull off any paint when the tape comes off.
With the bezel off you have easy access to the two bolts (# 2 in the diagram) that hold the arm/stop (# 7) in place. Remove the bolts, the arm comes out, and you have easy access to work on that pesky bolt # 5. Once it's freed up, you can clean and lube the threads for easy adjustment.
And after you do that side, I'll bet you'll be itching to do the same on the other side. Just because.
Good luck! Let us know how it works!

Happy to help.
If you replace the slotted screw with a 1/4"-20 bolt of the appropriate length you'll have an easy time if any future adjustments are needed. And if there's not one there already, add a 1/4"-20 jam nut to lock the adjustment in place.
And watch out for your paint!

Leaks anywhere in the system will cause a soft pedal. A year ago when you installed the new mast cyl and calipers (just 1, or all 4?), did you have a hard pedal after bleeding?
Kind of strange to hear that a caliper will leak every once in a while - in my experience, they've been good, until they're not, and then they don't get well again, they get replaced. Which has always been well after a year.
Caliper leaks are easy to see. With the wheel off, shine a light down through the top and look for wet pistons pushing against the pads. Wet is bad; dry is good. If they're leaking, not only are you losing fluid, but most likely your calipers are sucking in air past the seals when you take your foot off the brake.
Also, do you know whether or not your rotors are warped (even just a tiny bit). Warped rotors can cause the calipers to suck air.
I don't think I have a definitive answer to your question - you have a lot of places to check (including the hose-to-caliper and hose-to-brake line connections). But if you can find visual evidence of a fluid leak anywhere, you know where to start.

Wow. Totally stumped on that. No ideas, not even a wild-a$$ guess. But I'll bet a number of others on the forum can help. Start a new thread with 'odd caliper leaks' or something similar as the title, and spell out the whole story. Someone will have an answer. Good luck!
