Detailed Description

MPA Electrical NM4341 is a brake master cylinder engineered for vehicles equipped with front disc brakes, including the Chevrolet Camaro, Cadillac ATS, and Cadillac CTS. It is built as a standard replacement hydraulic component with an aluminum body, plastic reservoir, and included reservoir cap and seal to support proper brake fluid containment and system operation. The unit does not include a brake booster, push rod, mounting hardware, mounting bracket, sensor, or brake pressure switch.

This part cross-references 23347525 and 84614707 for the same application. If you are replacing a worn or leaking master cylinder on a 2016-2020 Camaro or a 2016-2019 ATS or CTS, NM4341 provides a direct-fit service part for the brake hydraulic system.

Common Problems This Part Can Address

• Soft or inconsistent brake pedal feel
• External brake fluid leakage at the master cylinder
• Internal hydraulic bypass causing reduced braking response
• Brake warning concerns related to master cylinder wear
• Loss of braking performance from a failing hydraulic seal

Installation Notes and Tips

Before installation, confirm vehicle fitment by year, make, model, and front disc brake configuration. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system with DOT 3 fluid after installation. Inspect the brake booster, lines, and fittings for wear or contamination so the replacement master cylinder can operate correctly.

Quality Assurance

MPA Electrical tests each unit against OE specifications using proprietary processes and strict validation protocols. That process is used to help ensure consistent braking performance right out of the box for the Camaro, ATS, and CTS applications listed above.
