Drum brake ovality?

[bikemaniac]

Hi,
When applying my stock drum brakes, the decelleration is jerky in the sense that for each wheel revolution the brakes brake harder at approx 50% of a revolution and softer at the remaining 50%. Is this normal or can/should it be solved?

Next, concerning brake performance: When riding in town at lets say 40 mph approaching an intersection with lights .... and the lights suddently turn red, I have a very long brake distance compared to a modern car, I almost every time end up in the intersection and have to back up a little. I feel I really press the brakes hard .... but maybe I should REALLY press with all I have got? I know the car weighs more than 2000 pounds, but still .... how would you describe the brake performance?
