Description
The Wilwood Part Number 260-13624 is a high-performance compact side mount master cylinder designed for limited space applications in automotive systems. This innovative component features a 7/8-inch bore and a 3/8-24 banjo outlet, ensuring reliable fluid flow and efficient brake operation. Its ultra-short 3.37-inch body provides an additional 2.16 inches of clearance between the mounting boss and the fluid outlet, making it ideal for tight installation environments without sacrificing performance. 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 constrained spaces. The master cylinder’s piston offers a full 1.12-inch stroke, meeting or exceeding the stroke capacity of most full-size cylinders for consistent brake pedal feel and responsiveness.
Constructed from durable black E-coated aluminum, the body resists corrosion and maintains a long-lasting finish even under harsh conditions. The fluid inlet port is designed to accommodate the standard reservoir included in the kit, with an 11/16-20 internal thread option available for custom reservoir configurations. The top radius placement of the fluid outlet port minimizes trapped air, enhancing brake system bleeding and efficiency. This master cylinder kit is suitable for various automotive applications requiring compact design with uncompromised performance, and it complies with industry standards for quality and durability. Its versatile features and robust construction make it a dependable choice for race cars, custom builds, or any project where space is at a premium without sacrificing brake performance.
