Drum brake
In Turkish: Kampana fren
In short
A drum brake works by brake shoes expanding against the inside of a drum in the wheel hub.
It is common on small motorcycles and scooters, especially at the rear. The lever or pedal turns the brake arm via a cable or rod, and a cam spreads the shoes against the drum.
- Free play grows as the shoes wear; adjust it with the nut at the end of the cable or rod.
- Many models have a wear indicator (an arrow and a mark) on the brake arm; replace the shoes when the arrow passes the limit mark.
- A wet drum brakes weakly for a while; dry it with light braking after riding through water.
Also known as (including Turkish names)
