• Available bore sizes ranging from 5/8" to 1-1/8" to match various brake system requirements and optimize hydraulic pressure and pedal effort.
• Machined billet aluminum reservoir with classic finned styling, reducing weight while enhancing heat dissipation for improved fluid temperature management.
• Remote flange mount design enables flexible installation options, making it easier to integrate into custom brake setups or retrofit applications.
• Durable construction with high-quality materials ensures long-lasting performance and resistance to corrosion and wear.
• Compatible with a wide variety of brake fluid types and systems, providing versatility for street, strip, or track use.
• Precision-machined components deliver consistent hydraulic pressure and excellent pedal feel for enhanced driver confidence.
• Designed to work seamlessly with Wilwood’s extensive line of brake components, including calipers, boosters, and proportioning valves.

Construction & Design

The Wilwood Compact Remote Flange Mount Master Cylinder features a robust design focused on durability and performance. The reservoir is crafted from billet aluminum, which not only reduces overall weight compared to traditional steel or plastic reservoirs but also offers superior heat dissipation through its finned surface. This passive cooling helps maintain brake fluid integrity during demanding driving conditions.

The master cylinder body is engineered for strength and precision, ensuring reliable hydraulic pressure delivery. Its remote flange mount configuration allows for flexible placement in the engine bay or chassis, accommodating custom builds and tight packaging constraints. The compact length of just over three inches makes it one of the shortest master cylinders available, ideal for applications where space is at a premium.

Every component is machined to exacting tolerances, providing smooth piston operation and consistent performance over time. The finish and fitment reflect Wilwood’s commitment to quality and attention to detail, making this master cylinder both a functional and visually appealing upgrade.

Installation & Fitment

The remote flange mount design simplifies installation by allowing the master cylinder to be mounted in various orientations and locations, depending on your vehicle’s layout and brake system design. This flexibility is particularly beneficial for custom builds, hot rods, and race cars where standard master cylinder placement is not feasible.

Installation typically involves connecting the master cylinder to your existing brake lines and mounting it securely using the flange hardware. No special modifications or machining are generally required, making it a straightforward upgrade for experienced installers and professional shops alike.

• Compact size fits in tight spaces where standard master cylinders cannot.
• Flange mount allows flexible positioning for custom brake setups.
• No cutting, drilling, or special tuning is required for most applications.
