Wilwood 260-12387 7/8" Bore Side Mount Compact Brake Master Cylinder

The Wilwood 260-12387 is a side mount compact remote brake master cylinder engineered for limited space applications that still require the output capacity of a full-size master cylinder. Featuring a 7/8" bore diameter, this master cylinder delivers professional-grade braking performance in an ultra-compact package.

Key Features:

• Ultra-compact 3.37" body length provides 2.16" of additional clearance between mounting boss and fluid outlet
• Full 1.12" piston stroke meets or exceeds the stroke capacity of most full-size cylinders
• Integral side mounting lugs with 3.00" center-to-center distance eliminate traditional mounting flange for easier installation in tight spaces
• 1/8" NPT fluid outlet port located at top radius of cylinder bore reduces chances of trapped air
• Enhanced fluid inlet port accommodates standard reservoir (included in kit) and features 11/16-20 internal threads for custom reservoir arrangements
• Black E-Coated aluminum body resists corrosion and maintains durable, long-lasting finish
• 7/8" bore diameter optimized for balanced brake system performance

This compact combination master cylinder is ideal for race cars, custom builds, and modified vehicles where space is at a premium but braking performance cannot be compromised. The side mount configuration offers flexible installation options in cramped engine bays and chassis applications.
