Internal hose degradation and environmental exposure over time can lead to pressure loss, uneven caliper response, and dangerous fluid leaks in brake hydraulic systems. Upgrading to this premium DFC OE replacement caliper restores immediate hydraulic response, eliminates internal hose expansion, and ensures consistent braking performance under heavy fleet load conditions. This caliper is engineered with heavy-duty materials to withstand severe operational demands, providing a reliable solution for fleet maintenance and industrial applications.
Designed to drop directly into existing setups, this rear right caliper features a silver zinc coating for corrosion resistance and long-term durability. Its precise fitment covers a broad range of Buick Park Avenue and Cadillac DeVille models from the early 2000s, making it an ideal replacement for aging OEM components. The caliper’s robust construction ensures volumetric stability during braking, reducing caliper drag and improving overall vehicle safety and control. Its compatibility with heavy-duty fleet and passenger vehicles emphasizes its structural integrity and high-performance standards, suitable for demanding commercial applications.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 underscores the importance of proper hose routing and caliper positioning. When installing this caliper, ensure hoses are routed to avoid chassis chaffing and maintain full lock twist clearance to prevent premature wear. Always verify the mounting brackets on heavy commercial frames are secure and free of damage to guarantee optimal operation and safety. Proper inspection and routing are critical for maintaining hydraulic integrity and extending service life.
Prior to installation, physically inspect your existing line length, banjos, and flare fitting threads. Variations in vehicle wheelbase and production runs can alter line routing on fleet and utility applications. Confirm these details to ensure compatibility and avoid installation delays.
