This compact side mount master cylinder from Wilwood is engineered for applications where space is limited yet reliable braking performance is essential. Featuring a short 3.37-inch body, it provides an additional 2.16 inches of clearance between the mounting boss and fluid outlet, making it ideal for tight engine bays, industrial equipment, or custom vehicle builds. The integral side mounting lugs with a 3.00-inch center-to-center distance eliminate the need for a traditional mounting flange, allowing for flexible installation in confined spaces. The 1/8-inch NPT fluid outlet port located at the top radius reduces trapped air, promoting more efficient brake bleeding and consistent pedal feel. Its black E-Coated aluminum body offers excellent corrosion resistance, ensuring durability and longevity in demanding environments. The cylinder’s 1.12-inch piston stroke surpasses many full-size cylinders, providing ample movement for precise control. Designed to accommodate the included standard reservoir and featuring 11/16-20 internal threads for custom reservoir configurations, this master cylinder combines compact design with heavy-duty performance, suitable for automotive, industrial, and fleet applications where space constraints are a concern.
