Brakes seem to start getting hard/stiff by after a long drive. Still hard for a few hours after but by the next day they are normal again.

72 RR 440. Brakes are fine for about the first 30 minutes. Stops well too. Drums all the way around. Then they start getting a little hard. Once I park it the brakes seem to be even harder but by the next day they are normal again. Any ideas?

On short drives they don’t seem to get stiff at all or harden up after parking. Any idea what could cause this?

Manual or power brakes? If power it sounds like the booster is losing assist.

Not clear, is the pedal firmer, or is it you need to press harder to get the same braking effect you had up to the first 30 minutes of driving?

It could be the type of brake shoe [ lining ]. As the material warms up, it loses it's braking efficiency. Try a different brand of brake shoe.
