404 brakes

Hey guys,

My front brake pads (69 404) are stuck to the rotor and won't let go. I have rebuilt the master cylinder and calipers, cleaned and reinstalled the slave cylinder still when used once or twice they come back and stay stuck to the rotor, any ideas?Thanks.

Since the 404 seems to be very old, I suggest you change the brakes to new one's, more safty and less problems.
