Manitoba Airbrake Practice Exam

Question: 1 / 400

What is the purpose of the brake shoe lining in an air brake system?

To absorb sound during braking

To provide friction against the brake drum when the brakes are applied

The brake shoe lining plays a critical role in the function of an air brake system by providing the necessary friction against the brake drum when the brakes are applied. This friction is essential because it generates the stopping force that slows down or halts the vehicle. When the driver engages the brakes, air pressure is used to push the brake shoes outward against the drum, and the lining material is designed to withstand high levels of heat and wear while maintaining effective friction levels. This ensure that the braking system operates safely and reliably under various driving conditions. The choice of materials and construction of the brake shoe lining also contributes to the overall performance and longevity of the braking system.
