Master Cylinder Short Side Mount 3/4in

The Wilwood Master Cylinder Short Side Mount 3/4in (Part No. 260-12385) is a compact hydraulic brake master cylinder engineered for custom brake system builds and retrofit applications. With a 0.75-inch bore and 1.120-inch stroke, this aluminum master cylinder delivers precise pedal modulation and responsive brake line pressure control in space-constrained installations where traditional remote reservoirs may be impractical.

The short side mount configuration positions the cylinder's reservoir adjacent to the main body rather than remotely, reducing overall footprint while maintaining full functionality. Its 0.75-inch bore is optimized for lighter-duty brake applications and vehicles where reduced pedal pressure or smaller hydraulic displacement is preferred. The aluminum construction resists corrosion and offers a weight advantage over cast-iron alternatives, critical for performance and restoration builds. Black paint finish provides durability and a professional appearance. This kit configuration includes all necessary components for direct or remote side reservoir installation, allowing builders flexibility in system layout depending on underhood space and design constraints.

This master cylinder is suited for street rods, custom muscle cars, vintage truck restorations, and race-oriented brake system upgrades where OEM master cylinders don't match modern performance requirements or don't fit modern caliper systems. Builders who prioritize compact packaging, reliable pedal feel, and simplified plumbing choose Wilwood master cylinders for their reputation in the custom and restoration market. The compact size makes it particularly valuable in engine-bay-limited platforms where space is at a premium.
