Internal hose degradation and environmental wear are common causes of pressure loss, uneven caliper response, and dangerous fluid leaks in fleet brake systems. This premium replacement caliper assembly restores hydraulic integrity, ensuring immediate response during heavy-duty braking and eliminating internal line expansion under load. Upgrading to this caliper provides a reliable, structural solution to maintain fleet safety and performance.
Constructed with high-quality materials, the DFC 331-47029 caliper features a durable zinc coating to resist corrosion and prolong service life. Designed for direct bolt-in installation, it fits contemporary and vintage heavy-duty vehicles, including 1967-1968 Buick Gran Sport models and other classic performance vehicles. Its robust build ensures consistent brake force application, essential in severe-duty applications where brake responsiveness and reliability are critical.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing to prevent chaffing and ensure full lock steering clearance. Always verify that the line mounting brackets are correctly positioned on heavy commercial frames to prevent stress and potential failure. Proper installation practices are crucial for maintaining hydraulic efficiency and vehicle safety in fleet applications.
CRITICAL: Verify Specifications
Before ordering, physically inspect your existing line length, banjos, or flare fitting threads. Variations in vehicle wheelbase and mid-year production changes can alter line routing on fleet and utility vehicles. Confirm dimensions to ensure proper fitment and avoid installation delays or hydraulic leaks.
