SSBC A28138CB-4 Billet Aluminum Dual Bowl Master Cylinder

The SSBC A28138CB-4 is a high-performance billet aluminum dual bowl master cylinder designed for demanding brake system upgrades on street rods, muscle cars, and custom builds. Precision-machined from aircraft-quality billet aluminum, this master cylinder delivers consistent hydraulic pressure and superior fluid displacement for improved pedal feel and braking response.

This dual-reservoir design separates the front and rear brake circuits, providing an added layer of safety by maintaining partial braking capability in the event of a circuit failure. The billet aluminum construction reduces weight compared to cast-iron OEM units while offering excellent corrosion resistance and a clean, polished appearance.

Key Features:

• CNC-machined billet aluminum construction for strength and lightweight performance
• Dual bowl (dual reservoir) design for independent front and rear brake circuit isolation
• Compatible with SSBC performance brake conversion and upgrade kits
• Superior corrosion resistance compared to cast iron master cylinders
• Clean, polished finish ideal for show and performance builds
• Designed for use with disc/disc or disc/drum brake system configurations
• Direct bolt-on fitment for applicable SSBC brake system applications

The SSBC A28138CB-4 master cylinder is engineered to meet the high standards of SSBC's (Stainless Steel Brakes Corporation) brake upgrade systems, making it an ideal replacement or upgrade component for enthusiasts seeking reliable, high-performance stopping power.
