Wilwood Compact Remote Flange Mount Master Cylinder with Aluminum Reservoir - 1" Bore

Universal Fitment

Part #: 261-16840-1.00

Overview

The Wilwood Compact Remote Flange Mount Master Cylinder with Aluminum Reservoir is a precision-engineered hydraulic component designed for high-performance braking systems. Often referred to as the “shorty” master cylinder due to its compact size of just 3.375 inches in length, this unit is ideal for applications where space is limited but reliable brake control is essential. Its compact design makes it a popular choice for hot rods, custom builds, and race vehicles where efficient packaging and weight savings are priorities.

This master cylinder is suitable for enthusiasts and professional builders who demand consistent pedal feel and precise brake modulation. Whether you are upgrading your braking system for improved performance or replacing a worn factory unit, this Wilwood master cylinder offers enhanced durability and responsiveness. The integrated aluminum reservoir features a classic finned design that not only reduces weight but also aids in passive cooling, helping maintain fluid integrity during intense driving conditions.

With a 1-inch bore size, this master cylinder is engineered to provide the right balance of hydraulic pressure and volume for a wide range of brake setups. It supports improved brake pedal feel and helps optimize braking performance, making it a reliable choice for street, strip, and track applications.

• 1-inch bore size optimized for balanced hydraulic pressure and fluid volume in performance brake systems.
• Machined billet aluminum reservoir with classic finned styling, offering lightweight construction and enhanced heat dissipation.
• Flange mount design for secure and straightforward installation in a variety of vehicle configurations.
• Durable construction designed to withstand demanding driving conditions and repeated use.
• Compatible with a wide range of brake fluids and brake system components.
• Ideal for hot rods, custom builds, and performance vehicles requiring compact, efficient master cylinder solutions.
• Precision engineering ensures consistent brake pedal feel and reliable hydraulic pressure delivery.

Construction & Design

The Wilwood Compact Remote Master Cylinder features a robust design focused on durability and performance. The reservoir is crafted from billet aluminum, which provides a lightweight yet strong enclosure for brake fluid. Its finned surface is not only visually appealing but also serves to dissipate heat passively, helping to maintain optimal fluid temperatures during heavy braking.

The compact housing and flange mount configuration allow for flexible installation options, especially in vehicles where space constraints make traditional master cylinders impractical. The bore size of 1 inch is carefully selected to balance fluid displacement and pressure, ensuring effective brake system operation without excessive pedal travel or stiffness.

Every component is manufactured to tight tolerances to guarantee smooth piston operation and long service life. The design minimizes internal friction and wear, contributing to consistent brake performance over time.

Installation & Fitment

This master cylinder is designed for flange mount applications and can be integrated into a variety of brake system setups. Its compact size facilitates installation in confined engine bays or custom chassis configurations where space is at a premium.

Installation typically involves mounting the unit to the firewall or bulkhead using the flange, connecting the brake lines, and filling the reservoir with the appropriate brake fluid. No special modifications, cutting, or drilling are generally required when replacing an existing flange mount master cylinder of similar size.

• Flange mount design for straightforward attachment.
• Compact size fits tight engine bays and custom applications.
• No cutting, drilling, or special tuning required for most installations.
