Unlike some small scooter brake units that use bands that \u003cem\u003econtract\u003c\/em\u003e or \u003cem\u003eclamp-down\u003c\/em\u003e on a spinning drum to provide the braking pressure, this brake unit's shoes \u003cem\u003eexpand outwards\u003c\/em\u003e to grip the inside of the drum. This is essentially the same system used on an automotive drum brake, but on a much smaller scale. External labeling states this is a \"Servo Brake\" from Xun Lin Brake. This is an outside view the 90 mm unit. There is an almost identical 100 mm version in stock as well.\u003cbr\u003e\u003cbr\u003e\n\u003cb\u003eNote:\u003c\/b\u003e This rear brake has been discontinued and is no longer available.
