The kind of brake system used on a trailer is determined by numerous elements, together with the trailer’s weight, towing car, and supposed use. There are two main sorts of trailer brake techniques: electrical over hydraulic (EOH) and surge brakes. EOH brakes use an electrical solenoid to activate a hydraulic piston, which applies stress to the brake sneakers. This technique is often used on smaller trailers and is appropriate for light-duty towing.
Forms of Trailer Brake Methods
The selection of brake system is determined by the trailer’s weight and towing car.
- Electrical Over Hydraulic (EOH) Brakes
- Surge Brakes
EOH brakes are appropriate for smaller trailers with a gross trailer weight (GTW) score of as much as 4,500 kilos. These brakes use an electrical solenoid to activate a hydraulic piston, which applies stress to the brake sneakers. They’re comparatively straightforward to put in and require minimal upkeep.
Surge brakes, alternatively, use a mechanism referred to as a “surge valve” to use stress to the brake sneakers when the trailer is in movement. This technique is often used on bigger trailers with a GTW score of over 4,500 kilos. They’re extra complicated and require common upkeep to make sure correct operation.
Brake Fluid and its Significance, How you can wire trailer brakes
Brake fluid performs an important position in sustaining a dependable braking system. It’s used to transmit stress from the brake grasp cylinder to the brake sneakers, permitting the car to sluggish or cease.
