Wilwood High Volume Tandem Master Cylinder - 1-1/8 Inch Bore, Black Finish
Description

The Wilwood high volume tandem aluminum master cylinder, part number Wil260-8556-BK, offers reliable performance for a variety of automotive brake systems. Crafted from high-pressure die cast aluminum, this master cylinder is designed to deliver a lightweight yet durable solution, weighing only 3 pounds*significantly lighter than traditional cast iron units. Its black e-coat finish provides corrosion resistance and a sleek appearance that complements modern brake setups. Suitable for power brake applications, the 1-1/8 inch bore size is ideal for systems utilizing vacuum or hydraulic assist, ensuring optimal hydraulic pressure and braking efficiency. The master cylinder features fluid outlet ports on both sides of the bore for versatile installation options, and its mounting flange fits most domestic vehicles from the mid-1960s to today with measurements ranging from 3.22 to 3.40 inches. The stroke length is set at 1.10 inches, with a 2:1 volume ratio between primary and secondary chambers, providing predictable pedal feel and consistent braking performance. This component is suitable for both manual and power-assisted applications, although the 7/8 inch bore model is primarily for manual use and includes a pushrod, whereas the 1-inch bore version does not include a pushrod. For enhanced system integration, Wilwood offers a matching combination proportioning valve kit, which includes brackets and stainless lines designed specifically for use with this master cylinder. Overall, this master cylinder delivers high-volume fluid transfer, lightweight construction, and versatile compatibility to meet the demands of custom and restoration projects alike.

Features:

  • Aluminum construction for lightweight durability
  • Available in 1.00 inch and 1-1/8 inch bore sizes for versatile applications
  • Black e-coat finish for corrosion resistance
  • Designed for power brake systems with vacuum or hydraulic assist
  • Fluid outlet ports on both sides for flexible installation
  • Mounting flange compatible with most domestic vehicles from the 1960s to present
  • Stroke length set at 1.10 inches with 2:1 volume ratio for consistent braking
