SKU: 390783
Internal hose degradation and environmental wear are common causes of pressure loss, uneven caliper response, and dangerous fluid leaks in heavy-duty fleet braking systems. These issues can lead to spongy pedal feel, delayed brake engagement, or caliper sticking, compromising safety and brake performance. Upgrading to this premium replacement line restores immediate hydraulic response, eliminates internal line expansion under heavy load, and enhances overall braking stability for severe-duty applications.
Designed with heavy-wall construction and high burst-pressure ratings, this hydraulic line kit is engineered to withstand demanding commercial environments. The robust material composition ensures resistance to chafing, abrasion, and extreme temperatures, making it suitable for industrial machinery transport, fleet vehicles, and severe-duty trucks. Its precise fitment guarantees compatibility with original mounting points, simplifying installation and reducing downtime.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of routing hydraulic lines properly to prevent chassis chaffing and ensure full lock clearance during steering operations. Always verify the existing line length, mounting brackets, and flare fitting threads before ordering replacements, as fleet and utility vehicle configurations often vary mid-year or across wheelbase options. Proper line routing and bracket placement are critical for maintaining system integrity and avoiding premature wear or damage.
CRITICAL: Verify Specifications
Before ordering, physically inspect your existing hydraulic line, fittings, and routing paths. Variations in vehicle model year, wheelbase, and chassis configuration can alter line lengths and connection types. Confirm measurements and fitting threads to ensure compatibility and avoid installation delays.
