2. Detailed Product Pictures

Drum brakes can be grabby if the drum surface gets light rust or if the brake is cold and damp, giving the pad material greater friction. Grabbing can be so severe that the tires skid and continue to skid even when the pedal is released. Grab is the opposite of fade: when the pad friction goes up, the self-assisting nature of the brakes causes application force to go up. If the pad friction and self-amplification are high enough, the brake stays engaged due to self-application, even when the external application force is released.

While disc brake rotors can be machined to clean the friction surface (i.e., 'turning'), the same generally cannot be done with brake drums. Machining the friction surface of a brake drum increases the diameter, which might require oversized shoes to maintain proper contact with the drum. However, since oversized shoes are generally unavailable for most applications, worn or damaged drums generally must be replaced.

It is quite simple to machine brake drums if one has a slow running lathe (one rule of thumb is that cast iron should not be machined faster than fifty feet per minute). Usually it is only necessary to machine away the ridge that forms that makes brake drum removal difficult, especially if the brakes are self-adjusting. In severe cases the ridge can make the brake drum captive, however most drum brake designs provide a way to externally release the self-adjusting mechanism in order to ease drum removal and service.
