hard pedal intermittent 1975

Hi everybody i'am a new member on this site, hope you can help me! i have a little brake problem here

About 10 minutes after starting the car and driving high or low speed my brake pedal becomes hard and it's really hard to brake, after i stop the car pushing hard on the pedal everything becomes ok and i can ride it as long as i want without problem :confused

Booster seems ok when checking at start with pressure on pedal, little vacuum valve seems ok too.

The only thing i noticed is the rear galipers are warmer than the front ones after many braking period, shoul be the opposite right?

Any suggestion? .........thanks!

Could be the rubber hoses, are they original??? They collasp inside, and don't let the fluid flow.

hoses are new, tonight i did remove the little white teflon anti rattle for the pads at the rear, seems to be a sticking brake pads due to these teflon, i'll try it tomorrow and see how it goes.......thanks for the help!
