Internal hose deterioration and exposure to environmental elements can lead to pressure loss, uneven caliper response, and potential fluid leaks, compromising braking performance and safety. Upgrading to this heavy-duty PowerStop Autospecialty caliper restores hydraulic responsiveness and eliminates internal line expansion under severe braking loads, ensuring consistent stopping power for demanding fleet operations.
This caliper is a direct bolt-on replacement engineered for severe-duty applications. Designed with a floating caliper configuration and complete mounting bracket, it features new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware for reliable installation. The high-temperature EPDM rubber dust boots and premium assembly lubricants ensure smooth operation and long-term durability in harsh conditions. Every caliper undergoes 100% pressure testing to meet rigorous quality standards, providing fleet managers and mechanics with a proven, high-performance solution.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing to prevent chaffing and ensure full lock steering clearance. Always verify the existing line length and fitting threads before ordering to accommodate mid-year production changes or wheelbase variations common in fleet and utility vehicles. Proper line installation is critical to prevent fluid leaks and maintain optimal hydraulic response under severe conditions.
