1965 fury front brake

[buicker]

Hi! On My 65 fury with power brake and drum brake on all wheel , the front brake don't come back, I have changed the wheel cylinder, and the spring, but still the shoe won't come back all the way, this mean that as soon as I touch the brake the front wheel will locked. I am wondering if the master cylinder could cause this the problem?

Brake hose is probably the culprit. typical hose failure has the inside failing and it starts to act like a one way valve... That is it lets the higher pressure activate the brakes, but the springs aren't enough to let the cylinders retract.

Here's a video illustrating the problem. Yea, this is a disc brake caliper, but it's the same principal.

hoses are not that old , a few years, but i'll check that.
