Detailed Description

MPA Electrical NM4122 is a brake master cylinder designed to restore hydraulic braking performance on Dodge Dakota and Mitsubishi Raider trucks equipped with front disc brakes. The 1.125-inch bore diameter supports proper brake pressure delivery, while the aluminum housing and plastic reservoir provide a practical OE-style replacement configuration. This unit includes the reservoir, cap, and gasket or seal, and it is specified for DOT 3 brake fluid.

This part cross-references Chrysler/Mopar applications such as 05142652AA and 05175103AA for the same application. If you are replacing a worn or leaking master cylinder on a 2005-2010 Dodge Dakota or 2006-2009 Mitsubishi Raider, Part Number NM4122 is built to match the original hydraulic layout for front disc brake systems.

What It Helps Address

• Low or inconsistent brake pedal feel
• External brake fluid leakage at the master cylinder
• Internal hydraulic bypass that reduces braking pressure
• Brake warning symptoms caused by master cylinder wear
• Loss of braking performance from an aging hydraulic unit

Installation Notes and Tips

Verify vehicle year, make, model, and front disc brake configuration before installation. Bench bleeding the master cylinder before mounting helps remove trapped air from the hydraulic circuit and supports proper pedal feel after installation. Inspect brake lines, fittings, and the brake booster mounting surface for wear or contamination before connecting the new unit. Use only DOT 3 brake fluid as specified.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols drawn from a broad OE sample library. That validation process is used to help ensure consistent braking performance right out of the box.
