Detailed Description

MPA Electrical NM1912 is a brake master cylinder built to restore hydraulic braking performance on 1982-1983 Chevrolet Camaro and 1982-1983 Pontiac Firebird models equipped with front disc brakes. The aluminum housing helps keep weight down while maintaining the dimensional accuracy needed for proper brake system operation. This unit is tested against OE specifications using controlled validation processes and sample-based comparison methods to support consistent pedal feel and fluid pressure delivery.

This part number, NM1912, is a practical OE-style replacement for drivers servicing a Camaro or Firebird brake hydraulic system. It includes the reservoir and cap, while mounting hardware, push rod, seals, and brake booster are not included. This part cross-references GM 18009367 and 18013414 for the same application.

What It Helps Fix

• Low or inconsistent brake pedal response
• Internal master cylinder leakage
• Brake fluid pressure loss in the hydraulic system
• Soft pedal feel caused by worn master cylinder components
• Brake performance decline on front disc brake applications

Installation Notes and Tips

Before installation, verify bore size, mounting hole spacing, and brake line connection points against the original unit. Bench bleed the master cylinder before final installation, then fill with DOT 3 brake fluid and bleed the brake system thoroughly to remove trapped air. Inspect the brake booster, push rod, and lines for wear or contamination before reassembly, since those components are not included with NM1912.

Quality Assurance

MPA Electrical validates brake master cylinders against OE specifications using proprietary test procedures and strict inspection protocols. That process helps ensure the NM1912 brake master cylinder is ready for service on compatible Camaro and Firebird applications right out of the box.
