Description

The Dorman M390462 brake master cylinder is an OE direct replacement designed for Acura Integra models. It features an aluminum construction and includes a reservoir and sensor for complete functionality. The master cylinder has a bore diameter of 0.938 inches, two outlets with M10 x 1.0 rearward outlet size and a 1.0 thread pitch, and a secondary outlet thread diameter of 10mm. Mounting hardware is not included.

This master cylinder restores proper hydraulic pressure, replaces worn or leaking units, resolves spongy brake pedals, and addresses sensor-related warning lights. Installation requires thorough bleeding of the brake system and the use of appropriate brake fluid.
