Brake Master Cylinder Overview

Raybestos MC785 is a brake master cylinder for select Dodge and Fargo trucks from 1948-1958. It is built for applications that use a 1.500-inch bore, an iron body, and a two-port layout for hydraulic brake system service.

Key Features

  • Iron master cylinder construction for hydraulic brake service.
  • 1.500-inch bore size for the specified brake system application.
  • Three mounting holes with 0.394-inch mounting hole diameter.
  • Two outlet ports with a 3/8"-18 NPSF primary port thread.
  • Raybestos Element3 line product for classic truck brake repair.

Detailed Description

MC785 is a Raybestos brake master cylinder engineered for older Dodge truck and Fargo pickup brake systems. The fitment covers multiple 1948-1958 Dodge Truck and Fargo F-Series applications, including Dodge P410 Series, P420 Series, P400 Series, W300 Pickup, and several C- and B-series truck configurations. This part number, MC785, is specified for vehicles that require the listed bore, port, and mounting dimensions, making it a direct service replacement for the original hydraulic master cylinder in those applications.

The Element3 line focuses on application-specific brake components for restoration and repair work. For buyers searching for a Dodge Truck brake master cylinder or a Fargo pickup brake master cylinder, MC785 provides the dimensional and port configuration needed to match the original brake system layout. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

  • Restoring hydraulic brake pressure in worn master cylinder assemblies.
  • Replacing leaking or internally bypassing brake master cylinders.
  • Addressing low or inconsistent pedal response caused by master cylinder wear.
  • Repairing brake system issues on classic Dodge and Fargo trucks.

Installation Notes and Tips

Verify bore size, port thread, and mounting-hole layout before installation. Confirm the vehicle’s brake system configuration against the listed fitment, especially on heavy-duty truck applications with chassis-specific notes. Bleed the brake system thoroughly after installation and inspect all hydraulic connections for leaks.

Quality Assurance

Raybestos Element3 brake components are cataloged for application-specific fitment and dimensional accuracy. MC785 is identified by part number MC785 for ordering and verification against the correct brake system application.
