Electric brake controls are designed to apply the brakes of the vehicle's towed trailer. A signal is sent to the trailer's brake magnet or actuator when you apply the tow vehicle's brake pedal.The more power / voltage applied to the electromagnets, the greater the braking force. There are three basic types of brake controls on the market today which are a timed style, inertia style, and proportional. signal is sent to the trailer's brake magnet or actuator when you apply the tow vehicle's brake pedal.

Side effects of the vaccine. You can't get mumps from the MMR vaccine, and most people experience no side effects from the vaccine. A few may experience a mild fever or rash, and some people (mostly adults) have achy joints afterward for a short time.Less than one out of 1 million doses causes a serious allergic reaction.he mumps vaccine is usually given as a combined measles-mumps-rubella (MMR) inoculation, which contains the safest and most effective form of each vaccine.
Because the measles, mumps, and rubella viruses in the MMR vaccine are weak versions of the disease viruses, they may cause a very mild case of the dis-ease they were designed to prevent; however, it is usually much milder than the natural disease and is referred to as an adverse reaction to the vaccine.ecause the measles, mumps, and rubella viruses in the MMR vaccine are weak versions of the disease viruses, they may cause a very mild case of the dis-ease they were designed to prevent; however, it is usually much milder than the natural disease and is referred to as an adverse reaction to the vaccine.
