The primary components of self-energizing drum brakes include the brake drum, brake shoes, wheel cylinder, and various linkages. The brake drum, usually made of cast iron, rotates with the wheel, while the brake shoes are lined with a friction material that grips the drum when engaged. The wheel cylinder, located between the shoes, contains pistons that push the shoes outward when hydraulic pressure is applied.
Дискові гальма складаються з обертового диска, на якому розміщені гальмівні колодки. Коли водій натискає на педаль гальма, колодки притискаються до диска, створюючи тертя, яке зупиняє колесо. Однією з основних переваг дискових гальм є їхня здатність до більш швидкого охолодження, що зменшує ймовірність перегріву і вигорання гальмівного матеріалу. Це робить дискові гальма більш ефективними, особливо при інтенсивному використанні, наприклад, під час гальмування на високих швидкостях або в умовах гірських доріг.
Drum brakes operate through a system of shoes that press against the inner surface of a rotating drum to create friction and slow down the vehicle. While they are effective, drum brakes have several limitations, including heat dissipation issues, longer stopping distances, and a tendency to fade under heavy braking, especially in wet conditions. On the other hand, disc brakes utilize a rotor that spins alongside the wheel, with calipers that squeeze brake pads against the rotor, resulting in superior stopping power, shorter stopping distances, and better performance in adverse conditions.

Truck brake systems operate under high-stress conditions, generating significant heat during operation. However, when temperatures plummet, the brake drums can become cold and, in extreme cases, ice over, leading to reduced effectiveness and, consequently, increased stopping distances. The wood heater serves as a preventative measure against these cold-weather complications. By providing a steady source of heat, it helps maintain the optimal temperature of the brake drums, ensuring that the brakes remain responsive.
In terms of weight, drum brakes are typically lighter than disc brakes, making them suitable for compact vehicles where weight savings are crucial. However, when it comes to cost, drum brakes are generally less expensive to manufacture and purchase, which has led to their continued use in budget-oriented vehicles.

When it comes to vehicle safety, one of the most critical systems is the braking system. Among its various components, brake calipers play an essential role, especially in drum brake systems. Understanding brake drum calipers can help car owners appreciate their importance, recognize potential issues, and maintain their vehicles effectively.
Brake calipers are part of the braking system and function as the mechanism that applies friction to the brake pads or shoes, which in turn slows down or stops the vehicle. In drum brake systems, the caliper is linked to the brake drum, a cylindrical component that rotates with the wheel. When the driver presses the brake pedal, hydraulic fluid is sent to the caliper, which then pushes the brake shoes against the inner surface of the drum, creating friction that decelerates the vehicle.
