Question about '72 brake pulling
When I brake on my 72 the steering wheel pulls abruptly left. Is there an adjustment on the brake. I've never done any brake work.

There's no real adjustment for that but something is wrong with one side or the other
Start by putting the front up on stands, spin the wheels by hand and have someone press the brakes (car doesn't need to be running) and see of the passenger side even works
Check the pads/rotors for being worn out / grooved up, etc. Does the rotor on the passenger side seem clean, use a mirror to look at the back side as well. These don't have floating calipers so inside and outside are independant
If everything looks ok and seems to move when you step on the brake, bleed the system, might be air in the line to the passenger side (brakes should feel spongy though...)

Brake pedal doesn't feel spongy right? if it does you might have air in the lines and it need bleeding
Visual inspection
Either the drivers side is grabbing too much or the passenger side isn't grabbing enough
Scored up rotors, really smooth (polished) rotors, worn or glazed pads
Make sure you use a mirror and look at both sides.
Car is safely on stands (not harbor freight ones...)
With the wheels off you can have someone apply the brakes and make sure you see the inside and outside pads moving (not much room to move but if you look close you should be able to see them)
You can remove the pads by taking out the pin in the middle of the top of the caliper BUT they are sometimes a bit of a pain to get out and back in and whatever you do - don't touch the brakes if the pads are out!

I would guess a broke hose collapsing. I would replace both hoses (if one is bad won't be long til the other is) and bleed brakes.Would check that before calipers.
