Parking Brake Pedal Doesn't return

[money pit]

I bought a 70 Barracuda a couple of weeks ago. I'm fixing a lot of little things. I noticed the emergency brake pedal doesn't return when the parking brake is released. Is there a return spring that's supposed to pull the pedal up. I looked on Ebay and noticed on a 71 and up there is a return spring. Could I use the 71 and up pedal assembly? I also noticed when I set the parking brake the mechanism doesn't pull the parking brake cable. I think the cables are rusted. The car is from Virginia and does have rust issues. Thanks

The spring are on the cable inside the drums. Look in the bottom hole of the axle. Part of the spring can be seen there.

Does this spring cause the peddle to release? Thanks

If the cables are moving free & adjusted correctly the spring inside the drum will retract the whole cable pulling the pedal up .
If the cables are sticking you need to replace them or lube them until they move freely

The underside of the car is pretty rusted. I think the cables are probably locked up. Thanks
