A-Premium Brake Master Cylinder with Reservoir & Sensor for Chevy, GMC & Cadillac (2009-2014)

Overview

Introducing the A-Premium Brake Master Cylinder with Reservoir and Sensor, designed to integrate with select GM vehicles from 2009 to 2014. This unit combines a precise aluminum master cylinder, an included reservoir, and a built-in sensor to align with factory brake systems. The durable aluminum alloy body, paired with a 1.25 inch bore, aims for consistent hydraulic response and reliable fluid handling across daily driving, highway commutes, and routine towing tasks. While this part works alongside your existing ABS and braking hardware, it presents as a carefully engineered replacement that preserves familiar pedal feel and control without overpromising performance gains.
