Just like the brakes on any vehicle, the importance of having properly maintained scooter brakes cannot be overstated. A scooter brake gets worn with every use and sooner or later your scooter brake parts will need replacing. Just as most currently imported Chinese-made scooters use the common GY6 or QMB139 engine, most street scooter brakes for these scooters are of three very similar designs. As a result, scooter brake parts are usually interchangeable with a large number of brand name or generic makes and models. Scooter Parts Catalog ships brake shoes, brake pads, and other scooter brake parts usable on a wide number of scooters. Replacement parts for scooter brakes are not expensive, but damage and injuries caused by worn scooter brakes will always be too costly.
