Brake shoes are used in some types of drum brakes found on motorcycles and scooters. A drum brake consists of a brake drum that rotates with the wheel and brake shoes that press against the inside of the drum to slow or stop the vehicle.
The brake shoes are made of a friction material, such as asbestos or ceramic composite, which is attached to a steel backing plate. The friction material wears out over time and needs to be replaced when it becomes too thin.
One of the main advantages of brake shoes is that they are less expensive than brake pads. They also last longer than brake pads, but require more frequent adjustments.
The disadvantages of brake shoes are that they are not as effective at slowing down a vehicle as disc brakes, and they generate more heat and dust. In addition, drum brakes can be exposed to moisture and can rust or seize if not used for long periods of time.
It is important to check brake shoes frequently and adjust or replace them as necessary to ensure optimal braking performance and safety. As always, it is advisable to follow the vehicle manufacturer's recommendations on how often to replace the brake shoes and have a professional mechanic regularly inspect the brake system to make sure it is in good condition.
The service life of brake shoes can vary depending on several factors, such as the type of motorcycle, the quality and type of shoes, riding style and road conditions. On average, brake shoes should be replaced every 5,000 to 10,000 kilometers, but it is important to regularly check the condition of the shoes and replace them when they are worn out, even before this period.
Brake shoes can be repaired to some extent, but in most cases they will need to be replaced when they wear out. Some of the repairs that can be done on brake shoes include:
Note, however, that these repairs are generally not recommended for worn or damaged brake shoes. Keep in mind that brake shoes are a safety-critical component of the braking system, and worn or damaged shoes can lead to reduced braking performance and longer stopping distances.
It is advisable to replace brake shoes when they are worn or damaged, as repairs may not restore their full braking power and may compromise vehicle safety. In addition, if the brake shoes are worn unevenly or have deep grooves, it is time to replace them. It is recommended to follow the vehicle manufacturer's recommendations on how often to replace the brake shoes, and have a professional mechanic regularly inspect the brake system to make sure it is in good working order.
