brakes arent working as well anymor

Brakes are definitely not a strong area for me. I understand the basics of how they work, and when the shoes or pads need to be replaced, but that is about it.

I have a 1965 GMC with 4 wheel drums, no booster.
They used to offer more than enough stopping power, but recently it seems that I cant stop nearly as well. When I push down hard on the brake pedal it seems to hit a strong resistance part way down and then the brakes seem like they just arent engaging all of the way. The pads were last checked a couple thousand miles ago and had more than enough left.

I would like to see if anyone has any ideas what might be the problem before I try taking it to a brake shop. (8 lugs on 4 wheels means I am sitting at the shop waiting for quite a while)

Do you have a dual master cylinder on your truck and might that be the cause of the problem? Can't be too many things to check on a system like yours other than the basics: air in the lines, drums too thin or turned down too many times. Bad brake shoes? I'm sure a good brake shop could find the problem but a few things you might check first. HTH Bob

No, it's a single master cylinder.

I guess I will just throw it in the brake shop for the day and see what they come up with. I'll just make sure I have a ride so I dont have to sit there all day.
