Raybestos MC390131 Element3 New Brake Master Cylinder

The Raybestos MC390131 is a new (not remanufactured) brake master cylinder from Raybestos' Element3 line — engineered as a direct-fit replacement designed to match or exceed original equipment specifications. As the hydraulic heart of the braking system, the master cylinder converts brake pedal force into hydraulic pressure, distributing that force to the calipers and wheel cylinders to bring your vehicle to a controlled stop.

Key Features:

• New construction — not remanufactured; no worn core components
• Precision casting — manufactured from precision castings for an exact match to OE design and dimensions
• Reduced-weight casting design — does not add undue stress to brake booster mounting points
• OE fit, form, and function — engineered to match original equipment performance and installation requirements
• Complete assembly — includes reservoir; no sensor
• Raybestos Element3 line — part of a comprehensive hydraulic brake replacement program with over 1,600 models available

The Raybestos Element3 program is built for technicians and DIYers who demand a part that installs and performs just like the original. This master cylinder assembly is ready to install and restore proper hydraulic brake function.
