Description

The StopTech ACS.42B.1164 is a high-performance ST40 series right replacement brake caliper in a sleek silver finish. This caliper is designed for enthusiasts and racers seeking to maintain or upgrade their braking system with genuine StopTech components. Engineered for superior stopping power and consistent performance, it features a 36-40-28 piston configuration. This replacement caliper ensures precise fitment and restores optimal braking function to vehicles utilizing the StopTech ST40 brake kit.

Key features include its ST40 caliper series designation, a 36-40-28 piston size (likely referring to piston diameters in mm), and a silver color. It is specifically designed for the right side of the vehicle.

Installation of a brake caliper typically involves removing the old caliper, installing the new one, bleeding the brake lines, and checking for leaks. It's a moderately complex task that requires specialized tools and some mechanical expertise.

This caliper is a vehicle-specific component and requires a matching StopTech ST40 brake kit for proper fitment. It is not a universal-fit part and will not work without the correct application.
