Several things should be considered when investing in a premium-grade trailer and its equipment. Will it haul your cargo effectively? Is the towing vehicle strong enough to carry the weight? Which type of hitch should I buy?
However, brake safety is the most concerning factor when dealing with heavy-duty trailers.
No matter the speed of your towing vehicle, it takes tons of horsepower to stop the heavy-duty hauler, especially with cargo.
For instance, a 20-ton trailer hauling cargo at 40km/hr demands 830 horsepower for an emergency halt.
Understanding what a trailer brake is, how it functions, and why it is critical matters. Therefore, in this comprehensive read, let us explore the trailer brake system and its mechanism for various trailer types.
What Is Trailer Brake System?
A trailer brake system is a vital safety component that ensures the controlled stopping of a heavy-duty trailer. The design works with the towing vehicle’s braking system, providing the additional braking momentum mandatory to bring a heavy load to a secure halt.
How Do Trailer Brakes Work?
There are primarily two types of braking systems for trailers –
Electric Brake System:
The electric mechanism utilizes electrical signals from your vehicle to activate the trailer’s brakes. A controller in your car sends a signal to a brake actuator on the trailer.
The actuator applies hydraulic pressure to the brake calipers, which squeeze the brake pads against the brake rotors, slowing the trailer down.
Hydraulic Brake System:
The hydraulic system uses hydraulic fluid to transmit braking force from the towing vehicle’s brake pedal to the trailer’s brakes.
When you apply the brakes in your vehicle, hydraulic pressure transfers through a brake line to the trailer’s brake calipers.
The pressure forces the brake pads to clamp down on the brake rotors, slowing the trailer.
