brakes lock

I have a 1981 F100 that has an issue with the brakes locking. I've replaced shoes, pads, wheel and master cylinder without resolving the issue. Once you get the truck moving it does OK. After sitting for a bit and restarting, the rear brakes will be frozen.

What have I missed???

Thanks,
Duane

Prolly the parking brake cables, which have a history of rusting & corroding into one, solid mass. Search this forum or wait for Dave (Franklin2) he's offered some good suggestions on how to deal with it, some not too awful long ago.

Wheel cylinders have been replaced and brakes adjusted when new shoes were installed.

I appreciate your input.

your brake lines may still have air in them or even maybe clogged up might try undoing the lines from the master cylinder and blowing them out and ck your park break cable
