What is more important than getting your RV to a destination for the weekend? Being able to stop it, of course. The electric brakes on travel trailers and fifth-wheels are necessary to safely stop the combo, but they need regular maintenance and adjustments to continue operating properly. In fact, electric brakes need to be adjusted every 3,000 miles or annually, whichever comes first. During that mileage period, there can be some, although minimal, reduction in brake efficiency as the pads wear.
