Product Details

MPA Electrical’s NM4186 brake master cylinder is built to restore hydraulic braking performance on front disc brake vehicles. The manufacturer tests each unit against OE specifications using sample-based validation and controlled processes, helping ensure consistent brake feel and proper fluid pressure delivery after installation. This part cross-references 5110078J00 and 14145310 for the same application.

Compatible With 2012-2015 Chevrolet Captiva Sport, 2008-2010 Saturn Vue, 2007-2009 Chevrolet Equinox, 2007-2009 Pontiac Torrent, and 2007-2009 Suzuki XL-7, all with front disc brakes. The NM4186 part number is also useful when verifying replacement against OE-style brake hydraulic service needs for these platforms.

What It Helps Address

• Low or inconsistent brake pedal response
• Internal master cylinder seal wear
• Brake fluid leakage at the master cylinder
• Loss of hydraulic pressure in the brake system
• Brake performance decline on front disc brake vehicles

Installation Notes and Tips

Confirm vehicle fitment by year, make, model, and brake configuration before installation. This master cylinder does not include a reservoir, brake booster, push rod, sensor, or mounting hardware, so reuse or source those components as needed for the application. Bench bleeding is recommended before final installation, and the brake system should be filled with DOT 3 fluid and bled thoroughly after mounting.

Quality Assurance

MPA Electrical validates brake master cylinders against OE specifications using proprietary testing and strict inspection protocols. That process supports consistent hydraulic performance right out of the box for the listed Chevrolet Equinox, Pontiac Torrent, Saturn Vue, Suzuki XL-7, and Chevrolet Captiva Sport applications.
