Internal hose degradation and environmental exposure can cause pressure loss, uneven caliper response, and potentially dangerous fluid leaks in fleet brake systems. Upgrading to a high-quality replacement hydraulic line or caliper assembly restores immediate hydraulic response, eliminates internal line collapse, and prevents volumetric expansion during heavy braking. This caliper serves as an essential upgrade for maintaining fleet safety and reliable brake performance under severe-duty conditions.
Our replacement calipers are engineered for durability in demanding environments, featuring high-temperature EPDM rubber dust boots, stainless-steel hardware, and comprehensive assembly components. These units undergo rigorous pressure testing to ensure consistent performance and compatibility with original equipment mounting points. Designed for bolt-on installation, they require no modifications and fit directly in place of the original caliper, making them suitable for both professional and DIY fleet maintenance operations.
- Overall Length: 11.4-inch
- Fitting / Outlet Size: 10mm INV thread
- Application: Commercial-Grade / Heavy-Duty Fleet / Passenger Automotive Cross-Over

Expert Installation & Field Note
Ensure proper routing of the hydraulic line to avoid chassis chaffing or binding during full-lock steering cycles. Confirm that the mounting brackets are secure and free of corrosion or wear, especially on heavy commercial frames, to maintain optimal caliper function. Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of inspecting line length and fitting threads before installation to prevent leaks or fitment issues.
Before ordering, physically inspect your existing line length, flare fittings, and banjo bolts. Variations in vehicle wheelbase and production batches can alter routing and fitting configurations on fleet and utility vehicles. Confirm that your current components match the dimensions and thread sizes specified to avoid installation delays or compatibility issues.
