Internal hose degradation and environmental exposure often lead to pressure loss, uneven caliper response, and dangerous fluid leaks in hydraulic brake systems. Upgrading to this PowerStop OE replacement caliper restores immediate hydraulic response, minimizes volumetric expansion under heavy braking, and enhances overall brake reliability for severe-duty fleet applications. This caliper is engineered to withstand high thermal loads and harsh operating conditions, making it ideal for commercial vehicle use where consistent performance is critical.
Designed as a direct bolt-on replacement, this floating caliper includes a mounting bracket, new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware. The high-temperature EPDM rubber dust boots protect against dirt and moisture ingress, extending caliper lifespan. Each caliper is 100% pressure tested and inspected to ensure high-quality brake performance, providing a hassle-free installation experience without modifications. Its robust construction and precision manufacturing meet the demands of heavy-duty fleet operations, offering durability and dependable braking performance in severe environments.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing to avoid chassis chaffing and ensure full-lock steering clearance. Always verify that the existing mounting brackets and line lengths match your vehicle’s specifications before installation. Proper routing and secure mounting are essential to prevent line wear and ensure consistent hydraulic performance under demanding fleet conditions.
Before ordering, physically inspect your existing brake line lengths, banjos, or flare fitting threads. Variations in wheelbase and model year can alter line routing on fleet and utility vehicles. Confirm dimensions thoroughly to avoid installation issues and ensure compatibility.
