Internal hose degradation and environmental wear are common failure modes that lead to pressure loss, uneven caliper response, and potential fluid leaks in fleet and industrial brake systems. Replacing aging lines or caliper assemblies with our premium OE replacement calipers restores hydraulic responsiveness, eliminating volumetric expansion and ensuring consistent brake pedal feel under severe-duty conditions. This upgrade is essential for maintaining safe stopping distances and operational reliability across your fleet.
Our PowerStop Brake Caliper (Part Number: L6957) features a floating design with a mounting bracket, engineered for direct bolt-on installation without modifications. The caliper assembly includes new seals, guide pins, dust boots, bleeder screws, and stainless steel hardware clips, all assembled with premium lubricants to withstand high-temperature conditions. 100% pressure tested and inspected, these calipers guarantee high-quality, durable performance suitable for demanding commercial applications.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes proper hose routing to prevent chassis chaffing and ensure twist clearance during full-lock steering cycles. Always verify line length, flare fittings, and mounting bracket positions before installation, especially on fleet vehicles with varying wheelbases and production dates. Properly securing hoses and inspecting bracket mounts are critical steps to prevent chafing, leaks, and caliper drag during high-stress braking operations.
