Internal hose degradation and environmental exposure often lead to pressure loss, uneven caliper response, and dangerous fluid leaks in heavy-duty fleet vehicles. These issues compromise braking efficiency and safety under demanding conditions. Upgrading to this OE replacement caliper restores immediate hydraulic response and prevents fluid expansion during heavy braking, ensuring consistent performance in severe-duty applications.
This caliper is designed with heavy-wall construction and is pressure tested to withstand high burst pressures typical of commercial fleet use. It features corrosion-resistant finishes to combat rust and environmental wear, extending service life in harsh conditions. The caliper is a direct-fit replacement, dropping into your existing brake assembly without modifications, and includes hardware and brackets for simplified installation.
- Overall Length: 22.1 inches
- Fitting / Outlet Size: 10mm INV thread
- Application: Commercial-Grade / Heavy-Duty Fleet / Passenger Automotive Cross-Over

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper line routing to prevent chassis chaffing and accommodate full-lock steering cycles. Always verify the existing line length, flange types, and mounting brackets before ordering. Properly routing hoses to avoid sharp bends and ensuring twist clearance during steering movements are critical to maintaining hydraulic integrity and preventing premature wear or failure of the caliper assembly.
This line must match your existing length, fittings, and mounting configuration. Inspect all existing lines, banjos, and flare threads before ordering. Variations in wheelbase and production year may alter routing requirements. Confirm fitment with your current setup to avoid installation issues.
