Upgrade your trailer's braking system with this comprehensive brake line kit designed for single axle boat trailers. The kit includes a 264-inch (22ft) main brake hose with all male ends, which runs from the master cylinder or surge coupler to the first axle. A 3-way brass tee fitting with all female ends splits the brake line, allowing a 24-inch hose (male ends) to connect to the near-side caliper and an 80-inch hose (male ends) to extend to the far-side caliper. Constructed from DOT-approved flexible, UV-resistant rubber, these hoses deliver high-pressure performance for both drum and disc brake systems and are built to withstand harsh marine conditions. All fittings are brass, featuring 3/16-inch male inverted flare ends with a standard 3/8"-24 thread for secure, leak-free connections with most trailer brake components.
