When the brake cylinder pushes the two shoes apart, the leading shoe "wraps" with the rotating drum. This wrapping pushes the trailing shoe through the transfer bar into tighter contact with the drum providing the servo action.
Notice that your leading shoe nearly always has more brake lining than the trailing shoe and also notice that it requires more pedal effort to stop a car with drum brakes when it is going in reverse than it does when the car is moving the same speed in the forward direction.
Oh, dude, the self-servo action on drum brakes is when the leading shoe is pulled into the drum by the rotation of the drum itself. It's like the drum is saying, "Come here, shoe, let me stop you!" So, basically, it helps with the braking force and makes sure you stop when you need to. Cool, right?
Ah, the self-servo action on drum brakes is a beautiful thing. It's like nature working in harmony. When the brakes are applied, the rotation of the drum helps to push the shoes into the drum with more force, making braking more efficient. Just like adding a happy little tree to a painting, the self-servo action adds a touch of magic to how drum brakes work.
Self-servo action in drum brakes refers to the design feature that amplifies braking force when the brakes are applied. This is achieved through the rotation of the brake shoes, which causes them to press harder against the drum as it rotates. The self-servo action helps to improve braking efficiency and reduce the effort required to apply the brakes, making it a key component in drum brake systems.

What about 1993 Pontiac drum brakes, please be specific.
Drum brakes.
This will greatly depend on what kind of brakes you have and which parts you are trying to replace. Do you have disc or drum brakes? If you have disc brakes, do you want to replace the calipers, pads, or rotors? If you have drum brakes, do you want to replace the drum, or the shoes?
No. Drum brakes expand inside a rotating drum to stop the vehicle, disc brakes squeeze in against a rotating disc.
The rear brakes on a 1984 Chevy truck are drum brakes.
Only the rear brakes are drum brakes. The front brakes are disc brakes. To answer your question, twist the end wing nut by your drum brake. It tightens and adjusts how much you have to press on your rear brake lever.
Disc brakes and drum brakes.
No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
Disc brakes may have been an option but it would normally come stock with drum brakes.
A 1996 camaro has the same DISK brakes as a 2001. It does not have drum brakes.
Drum brakes do not have the stopping ability of disc brakes, so no not harder, but slower.
