The importance of high-quality traction and electric braking

You may have realized that to completely stop the vehicle and its trailer within the appropriate time frame, more than just the tractor's brakes are required. Considering the weight and speed of the trailer, it is obvious that the trailer also needs to tilt using its braking force.
This is achieved through the brakes of the trailer, which can be one of two types: surge (mechanical or hydraulic), which relies on inertia for automatic deceleration, or electric brakes, which need to be electrically connected to the tractor to operate. The principle behind the surge (also known as override or overspeed) brake is simple.
The coupling includes a sliding shaft connected to the traction ball. Due to vehicle deceleration, the axle slides when pushed and applies pressure directly to the mechanical linkage (mechanical brake) or the linkage connected to the hydraulic cylinder, thereby generating hydraulic pressure on the braking system (hydraulic brake). These often appear on camping trailers or boat trailers.
Electric trailer brakes can cause wear and slow down the trailer by activating the electromagnetic brake drum. When the surge brake operates independently, the electric trailer brake must be connected to the power supply of the towing vehicle and adjusted by the brake control unit or electric brake controller.
