Most trailers exploit electric brakes.
Electric brakes are used in trailers to supplement the tow vehicle's hydraulic braking development. Without electric trailer brakes, the tow vehicle's brakes could overheat and fail. Electric drum brakes are activated by a brake controller located in the tow vehicle. When the brake pedal is depressed, brake shoes press against the inside of the brake drum. Worn lining on the brake shoes may entail brake shoe replacement.
