Internal hose degradation and environmental exposure often lead to pressure loss, uneven caliper response, and dangerous fluid leaks in heavy-duty fleet applications. These issues compromise braking safety and consistency under severe stop-and-go conditions. Upgrading to this high-quality replacement brake caliper restores immediate hydraulic response, eliminating internal fluid expansion and caliper sticking, ensuring safer and more reliable braking performance in demanding commercial environments.
This OE replacement caliper is designed for direct bolt-on installation, matching the original specifications for fitment and function. It features a floating caliper configuration without a mounting bracket, simplifying installation and maintenance. Built with premium components, including new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware, it guarantees durability and operational efficiency even in the harshest conditions. The high-temperature EPDM rubber dust boots prevent dirt ingress and maintain optimal seal integrity during repeated heavy braking cycles. Fully pressure tested and inspected, this caliper ensures consistent, high-quality brake performance, reducing downtime and maintenance costs in commercial fleet operations.
- Overall Length: 9.0 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 hose routing to prevent chassis chaffing and ensure full lock steering clearance. Always verify proper line length, mounting bracket placement, and twist clearance during installation. Ensuring correct routing reduces chafe and prolongs component lifespan, especially in severe-duty fleet applications. Regular inspection of mounting brackets and hose positions on heavy commercial frames is critical for reliable operation and safety.
Always physically inspect your existing line length, banjos, or flare fitting threads before ordering. Variations in wheelbase and production runs can change line routing significantly on fleet and utility vehicles. Confirm measurements to avoid installation delays or fitment issues.
