If you have rear rotors that look like a rotor mounted on top of a drum brake, you will have an emergency brake inside the drum portion. The rear brake rotors are not flat like the front rotors for this style.
The E brakes have brake shoes and they have "Star" wheels for adjustment just like the regular drum brake. You really need to take off the rear rotors to inspect the inner drum portion. If you do adjust the E brakes without looking at the drum part, chances are the drum is pitted and rusty and you will be lucky to stop once before the E brake linings are ground off.
The other type of E brake works off the Rotor pads. You will see the brake cable attached to a lever on each wheel. There will be an Equalizing cable connecting both rear wheels with an adjustment point joining the main cable. Although the 3 clicks moves the main cable, to have both rear brakes equally tight you need the Equalizing properly adjusted.
