Brake Shoe / Set for trucks

Drum brake shoes are arc-shaped components of trucks equipped with friction linings. When the pedal is pushed down, they are pressed to the walls of the drum and ensure vehicle deceleration.

Types

Manufacturers' catalogues contain items with the following main characteristics:

• Installation axle. There are front and rear drum brake shoes.
• Number of cylinders in the system. The products may be driven by one or two cylinders. In the second case, braking is more efficient.
• Dimensions. They depend on the brand and the model of the truck.
• Type of fastening. At the online store, you can find components that are attached with screws or rivets. Unlike brake shoes for passenger cars, which are mostly glued, components with such fasteners are more durable.

Malfunctions and their reasons

Average replacement frequency is 100,000 km of mileage, or 5 years. The components may get deformed or abraded. The former often occurs due to a foreign object in the gap between the drum and the shoe, and the latter - due to the natural wear-out.

How to detect faults

Components failure is indicated by deteriorated braking and squeaking sound, increased fuel consumption, increased braking distance and pedal stroke. The degree of the wear-out may be determined by thickness, which is measured through a special hole in the shield. If the component service life has expired, you should buy drum brake shoes instantly and then contact specialists at a service station to have them installed on the truck.

Operation of the vehicle with faulty elements is prohibited. New components are to be installed in a kit per axle. After installation, avoid abrupt and prolonged braking for a few hundred kilometres.
