Master Cylinder Kit Short 1-1/8in

The Master Cylinder Kit Short 1-1/8in from WILWOOD is a compact brake master cylinder engineered for high-performance hydraulic brake systems where space is limited. Designed for automotive builders, hot rod enthusiasts, and racing professionals, this kit delivers responsive brake actuation in applications requiring a shorter overall profile without sacrificing hydraulic capacity. The compact architecture makes it ideal for custom vehicles, retrofitted brake conversions, and race cars where traditional full-length cylinders cannot fit within tight engine bays or chassis constraints.

This master cylinder features a 1.125-inch bore with a 1.120-inch stroke, delivering precise brake pressure modulation across the system. Constructed from aluminum with a durable black paint finish, the unit resists corrosion while maintaining a lightweight profile that reduces unsprung weight in performance applications. The design accommodates both direct or remote reservoir configurations, allowing installers flexibility in plumbing and reservoir placement depending on vehicle layout and cooling requirements. The short stroke design minimizes pedal travel while maintaining adequate pressure generation, critical for brake feel and confidence in demanding driving conditions.

Installation suits experienced fabricators, professional race teams, and serious automotive enthusiasts undertaking custom brake system builds. This kit functions as a direct replacement or integration component in drag racing, circuit racing, and street rod builds where OEM master cylinders prove incompatible with custom chassis geometry. Weighing 1.87 lbs, the compact footprint simplifies packaging without requiring extensive modifications to firewall or pedal box mounting points. Buyers should verify compatibility with existing brake lines, fluid specifications, and pedal ratio calculations to ensure optimal brake balance and modulation in their specific application.
