Description
The Wilwood 260-12385 Compact Side Mount Master Cylinder is designed for applications where space is limited yet reliable braking performance is essential. Its ultra-short 3.37-inch compact body provides an additional 2.16 inches of clearance between the mounting boss and fluid outlet, making it ideal for tight engine bays and custom setups. The integral side mounting lugs with a 3.00-inch center-to-center distance eliminate the need for a traditional mounting flange, further simplifying installation in confined spaces. This master cylinder features a full 1.12-inch piston stroke, ensuring compatibility with most full-size cylinders and delivering consistent brake pedal feel.
The top-radius 1/8-inch NPT fluid outlet port minimizes trapped air, promoting quick and reliable brake bleeding. The enhanced fluid inlet port accommodates a standard reservoir included in the kit and contains 11/16-20 internal threads for custom reservoir options. Its durable black E-Coated aluminum body offers excellent corrosion resistance, ensuring long-lasting performance in demanding environments.
Whether upgrading an existing brake system or designing a new custom setup, the Wilwood Compact Side Mount Master Cylinder provides the space-saving solution combined with dependable hydraulic performance.
