Perävaunujarrut

Perävaunujarrut refer to the braking system of a trailer. These systems are crucial for vehicle safety, especially when towing heavy loads, as they assist the towing vehicle's brakes in slowing down and stopping the combined vehicle and trailer. The design and type of trailer brakes can vary significantly depending on the trailer's size, weight capacity, and intended use.

Common types of perävaunujarrut include electric brakes and hydraulic brakes. Electric brakes are widely used on smaller to medium-sized trailers, particularly those used for recreational purposes like boat or utility trailers. They operate via an electric current sent from the towing vehicle's brake controller to an electromagnet within the trailer's brake assembly. When activated, the electromagnet pulls on a brake arm, which then applies pressure to the brake shoes or pads against the trailer's wheel drums or rotors.

Hydraulic brakes are generally found on larger and heavier trailers, such as those used for commercial hauling or heavy machinery transport. These systems utilize hydraulic fluid to transmit braking force. They can be either surge brakes, which activate automatically when the trailer decelerates relative to the towing vehicle, or independent hydraulic systems that are controlled by the towing vehicle, similar to electric brakes but using hydraulic pressure instead of electricity. Proper maintenance and adjustment of perävaunujarrut are essential for safe towing operations.
