How Many Kilometers Should Motorcycle Drum Brakes Be Replaced?
1 Answers
According to the mileage and driving habits (i.e., the frequency of braking), it is generally recommended to inspect them at around 60,000 kilometers. If the thickness of the brake shoes is less than 0.5 mm, they should be replaced. For riveted brake shoes, replacement should occur before the rivets are exposed; otherwise, the brake drum may develop linear scratches, requiring either drum resurfacing or complete replacement in severe cases. Introduction to Drum Brakes: Drum brakes consist of a brake drum fixed to and rotating with the tire, while the brake shoes are fixed to the axle. When the brake is applied, brake fluid pushes the brake shoes against the inner edge of the drum, creating friction to control the tire's rotation and achieve braking. Components of Drum Brakes: Drum brakes are composed of a brake backing plate, brake wheel cylinder, brake shoes, related linkages, springs, brake drum, and other accessories. They are primarily found on the rear wheels of some small vehicles. Drum brakes are cost-effective and offer higher absolute braking force, but they have a higher wear rate, resulting in higher overall costs.
