The ACDelco Gold 18M1107 is a professional brake master cylinder assembly engineered to meet stringent performance requirements. It has undergone pressure testing to guarantee safe and confident braking. This assembly meets the brake performance requirements of SAE J1153 and J1154 testing, providing reliability and quality. Its geometrical tolerance ensures a proper fit between the body and the plastic reservoir. The internal piston assembly and return spring work together to prevent brake drag, which can lead to premature brake pad wear. This ACDelco Gold master cylinder is ready for bench bleeding and installation right out of the box, requiring no additional assembly.
