Detailed Description

MPA Electrical NM4126 is a new brake master cylinder engineered to restore braking performance by replacing a worn or leaking hydraulic unit. It is built to OE specifications using tested processes and strict quality protocols, helping deliver consistent brake pedal feel and hydraulic pressure right out of the box. This unit uses a 1-inch bore, aluminum master cylinder body, and plastic reservoir for the listed Chrysler and Dodge applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Use NM4126 when servicing a 2008 Chrysler 300, 2008 Dodge Charger, or 2008 Dodge Magnum with front disc brakes and you need a direct replacement brake master cylinder.

What It Helps Fix

• Soft or inconsistent brake pedal feel
• Brake fluid leakage at the master cylinder
• Loss of hydraulic pressure in the brake system
• Brake warning symptoms caused by master cylinder wear
• Poor braking response from an aging hydraulic unit

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and brake configuration before installation. Bench bleed the master cylinder before mounting, then bleed the brake system thoroughly after installation to remove trapped air. Confirm the brake fluid specification is DOT 3 and inspect the booster, lines, and fittings for wear or contamination during service.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols. NM4126 is a new replacement part built to support reliable hydraulic performance for the listed Chrysler and Dodge applications.
