I have a 1964 Valiant with drum brakes all around. When i got it a few months ago i went over the brake system. I replaced all wheel cylinders, new spring kits, and brake shoes.
I also replaced the front drums with NAPA brand drums. Now when i hit the brakes when i'm over 50 mph the car vibrates pretty bad. Could one of the new drums be out of round and causing this.
I know that when the car is in the air the right front tires seems to grab a little every time the wheel goes around.
