Internal hose degradation, environmental wear, and prolonged exposure to harsh conditions can lead to pressure loss, uneven caliper response, and dangerous fluid leaks in fleet brake systems. Upgrading to this premium caliper assembly restores immediate hydraulic response, maintaining optimal braking force under severe-duty conditions. Its robust construction ensures resistance to volumetric expansion and caliper stickiness, which are common issues with aging stock components.
This PowerStop OE replacement caliper is engineered for direct bolt-on installation, eliminating the need for modifications. It features a floating design with a precision-mounted bracket, equipped with new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware. The high-temperature EPDM rubber dust boots prevent contamination and withstand extreme heat cycles, ensuring long-term operation. Each caliper undergoes 100% pressure testing and quality inspection to guarantee high performance and reliability across heavy-duty applications.
Designed to meet the demands of commercial fleet operations and industrial machinery, this caliper assembly offers consistent braking performance, excellent durability, and ease of installation. Its high-quality components and rigorous testing standards make it an ideal choice for fleet managers and professional mechanics seeking a hassle-free, long-lasting replacement solution for rear left calipers on compatible Nissan 350Z and Infiniti G35 models.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of correct hose routing to prevent chassis chafing and ensure smooth operation. Always verify that hoses are properly twisted to accommodate full-lock steering cycles and inspect mounting brackets on heavy commercial frames to confirm secure fitment. Proper routing and secure mounting are critical for prolonged component life and safe operation in demanding fleet environments.
Before ordering, physically inspect your existing line length, banjos, or flare fitting threads. Variations in wheelbase, manufacturing dates, and fleet configurations can alter line routing. Confirming dimensions ensures proper fit and prevents installation delays or system issues.
