PowerStop L5270 Disc Brake Caliper - Front Left

Front Left OE Replacement Caliper for Select GM Vehicles

PowerStop L5270 is a front left disc brake caliper built as an OE stock replacement for select Chevrolet, Buick, Cadillac, GMC, and Saab applications. It bolts into the original location and uses a floating caliper design with a 59.94 mm steel piston for direct-fit brake service on vehicles such as the Chevrolet Impala, Chevrolet Equinox, and GMC Terrain.

PowerStop’s Autospecialty OE Replacement Brake Caliper line focuses on stock-style fitment and remanufactured construction from the Chicago, IL facility. The L5270 is pressure tested for piston operation and leak prevention, then assembled with new seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips.

Detailed Product Overview

PowerStop L5270 is built for drivers who need a direct replacement front brake caliper without changing the original brake layout. It is a strong match for fitment-specific service on the 2014-2020 Chevrolet Impala, 2010-2017 Chevrolet Equinox, 2010-2017 GMC Terrain, and other listed applications. The remanufactured caliper and bracket are inspected for quality and safety, with pressure testing used to verify piston function and help prevent leaks.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Part Can Address
