Brake question...sorry.

66 coupe front GT discs stock rear drums. My problem is my rear drums are tightening up as I drive the to the point of smoking. I've taken them apart, cleaned everything thoroughly put everything back together and readjusted them. Still getting tight. I've had this set up on the car for a couple of years now with no problems. Any ideas.

Re: Brake question...sorry.

Are you sure that the self adjusters are on the correct sides?  They are marker R and L.

Yep that's all good. I've been driving the car with the present set up for quite a while and it's been fine. It hasn't been driven a lot the past couple months. Could it be the adjustable prop valve?It's not what you would call a quality part. Made near the Great Wall I think.

Re: Brake question...sorry.

With the exception of DOT 5 brake fluid is hygroscopic, absorbs water. Water equals rust, Your wheel cylinders could be rusted and siezing.
 How old is the rear flex line at the rear axle, it could be plugged or collapsing and holding the shoes out.
 I would do a complete brake fluid change  and put in a new set of wheel cylinders (cheap) and replace the flex lines front and back.
 I personally would not drive a vehicle very far that has brake issues.

I'm taking your advice Rudi. Ordered all the parts today plus a new prop valve. I looked this thing over and everything is put together as it should be so I'm not sure exactly what is wrong. But with the age of the hose in doubt and no more than what the rest of the parts cost I'm replacing everything including the brake hardware.

Re: Brake question...sorry.

My car did this when the rear flexible hose collapsed internally.
