YOU would actually have to remove the brake drum and measure them ,the width of the shoe then measure across the diameter of the drum .
Beind brake drum to replace
measure inside diameter of brake drum (where brake shoes touch drum) and measure outside diameter of brake rotors. usually if you look at wheel side of drums and rotors the size is stamped in millimeters on each
use a pad wear indicator :)
Brake drums can be resurfaced by turning the brake drum in a brake drum lathe. When the brake drum has deep grooves in it, it cannot be repaired.
A drum brake is a brake that uses friction caused by a set of shoes or pads that press against a rotating drum-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum.

Take the wheels off and measure the diameter of the brake rotor (disc) or drum with a ruler or tape measure.
Inside diameter. You will need to remove drum to do this. Take the drums to your local auto parts store, they can measure them with a micrometer and let you know if you need new ones or not.
Pull the hand brake and if it clicks more than 3 times the rear brakes are worn. The more clicks the more wear. If the master cylinder brake fluid is low they are worn. To see just how much they are worn you must remove the wheel and brake drum and inspect them.
The car will drive fine but the rear brake shoes may drag on the drum. This will quickly wear out the rear brake shoes, hurt you fuel mileage, and cause a loss of power. Replace the springs.
Pretty hard to do if you do not have the tools. If you really want to have it checked, then remove the drum and take it to your local garage. Have them turn the drum only a couple of thousands to check it.
