To get the surface area of drum brakes smooth, start by removing the brake drum from the vehicle and cleaning it thoroughly to eliminate any dust or debris. Use a fine-grit sandpaper or a brake lathe to gently sand the inner surface until it is even and free of imperfections. Ensure that you maintain a consistent pressure and check for any grooves or uneven wear that may require further attention. Finally, after smoothing, clean the surface again to remove any residue before reinstallation.

Why do brake drums on a vehicle run hot?
Drum brakes heat up faster, and stay hotter than disc brakes because of their design. Drum brakes have a drum covering two shoes which apply friction to nearly 90% of the drum surface. This friction causes drag which slows the drum from spinning, then stopping the car. Unfortunately, this use of friction, causes heat and the design of the drum restricts ventiliation. Disc brakes also use friction, but a piston applies much greater force on brake pads than shoes apply on a drum. The pads press on a spinning rotor, causing the drag and slowing the car. The design of the piston having greater force than the shoes, require less surface area to be used in applying the braking force. Less surface area = less friction points = less heat. But saying all this if your drum brakes are running hot then possible you are riding the brake with your foot while driving, the wheel cylinder is sticking causing the brakes shoes to drag and not fully retract, or the brake shoes are adjusted incorrectly and are dragging on the drum. Check the adjustment first thing to see that they are adjusted correctly. Also, the disc brakes have a much more open design allowing air to cool the brakes. Many brake systems have cross-drilled and/or slotted rotors which also allow heat to disapate much faster.
A car with front desk brakes and rear drum brakes has cylinders where?

93 Pontiac drum brakes?
What about 1993 Pontiac drum brakes, please be specific.
What is the surface area of a 55 gallon drum in square inches?
To calculate the surface area of a 55-gallon drum, we first need to determine the dimensions of the drum. A standard 55-gallon drum typically has a diameter of 22.5 inches and a height of 33.5 inches. The surface area of a cylinder can be calculated using the formula 2πr² + 2πrh, where r is the radius and h is the height of the cylinder. Plugging in the values for the radius and height of the drum, we can calculate the surface area in square inches.
What does it mean to machine the brake rotors and drum brakes?
The rotors in disc brakes and the drums are what the pads and shoes rub against to stop a car. With use, the surface can get grooves in it or a build up of rust scale; reducing the braking efficiency. To machine the rotors and drums, they are put on a lathe that cuts a new smooth surface on the face of each. Depending on wear, any given rotor or drum can probably be turned 2 or 3 times before needing to be replaced.
What causes Popping from rear when brakes are applied while driving?
if they are drum brakes it could be that the drums friction surface has a defect on it and everytime the shoes hit it it pops or it could be a bad hold down or quieter spring in the drum itself
How do you change car 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 brakes in rear on cavalier?
Drum brakes.
Why are disc brakes more powerful than drum brakes?
Simply a question of Force distributed over a much smaller area in the case of disk brakes (or higher pressure)
How does the surface area of a drum affect its pitch?
By it's TEMPTURE
Does disk and drum brakes work exactly the same?
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.
