Brake Drum The selection of a brake system also depends on your tow vehicle and the type and fully loaded weight of your trailer. For a trailer with a loaded weight of more than 1,500 pounds, many states require a separate braking system and a breakaway switch, located on the tongue of the trailer, to activate the trailer brakes in the event the trailer separates from the tow vehicle. |

Electric Braking Systems Electric/Electronic braking systems are the most common type of braking systems found on trailers today. These type braking systems connect the brake system on the tow vehicle to the brake system on the trailer. Electronically controlled brakes usually provide automatic and manual control for trailer brakes. This is accomplished by installing a electronic brake controller inside the tow vehicle. The controller or control box senses the braking force of the tow vehicle and in turn activates the brakes on the trailer. The control box may require adjustment or “tuning in” for variations in trailer load. Electric brakes are usually preferred over surge brakes because their operation is independent from the tow vehicle. If for some reason the tow vehicle loses its brakes, there would not be enough deceleration surge to activate the surge brakes. However, with electric brakes, the driver could manually activate the brake controller thus allowing the trailer to slow the entire rig. Electric trailer brakes are available as 'complete' assemblies, ready to bolt to the axle and connect the wires. |

Hydraulic Surge Brakes Hydraulic brake systems work by the "surge" or "push" of the trailer toward the tow vehicle during deceleration which automatically synchronizes the trailer brakes with the tow vehicle brakes. As the trailer pushes against the vehicle, the actuator telescopes together and applies force to its master cylinder, supplying hydraulic pressure to the trailer brakes. Surge brakes are independent hydraulic brakes activated by a master cylinder at the junction of the hitch and trailer tongue. As the tow vehicle applies its brakes, the "surge" of the trailer towards the decelerating tow vehicle compresses the master cylinder or the surge actuator. As this cylinder is compressed, force is applied to the master cylinder and from there to the braking cylinders. As these brakes are not controlled by the hydraulic fluid in the brake system of the tow vehicle. The hydraulic system of the tow vehicle should never be directly connected to the hydraulic system of the trailer. These systems are self-compensating and do not require adjustment for variation in trailer load. Surge braking systems are more expensive and usually only needed if you'll be using several different tow vehicles each requiring a brake controller. Manufacturers also establish the gross axle weight and provide a rating that denotes the maximum weight a single axle can carry. Follow the tow vehicle manufacturer’s recommendations for brake selection. Some states require braking systems on all axles of the trailer. So, check your state’s requirements by contacting the motor vehicle administration. When only one brake axle is being installed on a tandem axle trailer, the brakes should be on the rear axle for maximum system performance. Rotational torque applied to axles during braking shifts the equalizer and applies more weight to rear axle. If brakes are installed on the front axle, the wheel may skid during braking. Brakes on rear axle are more effective as the equalizers shifts and the rear tires dig in to the pavement. |
