Internal hose degradation and environmental exposure are common causes of pressure loss, uneven caliper response, and dangerous fluid leaks in fleet braking systems. Upgrading to a high-quality replacement caliper or hydraulic line is essential for restoring hydraulic responsiveness and preventing volumetric expansion under heavy braking conditions. This PowerStop OE replacement caliper is engineered to provide precise fitment and reliable operation in severe-duty applications.
Constructed with new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware, this caliper assembly ensures a leak-proof seal and smooth piston movement. The high-temperature EPDM rubber dust boots resist cracking and wear, maintaining caliper integrity over prolonged service intervals. Fully pressure tested and inspected, this caliper guarantees consistent brake performance, eliminating caliper drag and uneven pad wear. Its bolt-on design allows immediate installation without modifications, making it suitable for both DIY enthusiasts and professional mechanics working on fleet vehicles.
- Overall Length: 10.5-inch
- 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 chaffing against chassis components. Ensure the hose has adequate twist clearance during full-lock steering to avoid premature wear or damage. Always verify the mounting brackets and line lengths before installation, as fleet and utility vehicles often have variations in wheelbase and line routing that can impact fitment and performance.
Before ordering, physically inspect your existing line length, banjos, or flare fitting threads. Variations in production runs and vehicle configurations can alter line routing, which is critical for proper fitment on fleet and utility applications. Confirm measurements to avoid installation delays or line incompatibility.
