Wilwood 260-16520-P Tandem Compact Brake Master Cylinder Bore Corvette - 7/8 C2

The Wilwood 260-16520-P Tandem Compact Master Cylinder is a lightweight, high-performance replacement for C2 Corvette manual brake systems. Featuring a 7/8" bore diameter and ball burnished aluminum finish, this master cylinder comes with a specific length 3/8-24 diameter pushrod designed for 1963-1967 Corvette manual brake applications.

Key Features:

• Machined from high-pressure die-cast aluminum for exceptional strength and weight savings
• Weighs only 3.25 lbs—over 50% lighter than cast-iron factory tandem units
• Full 1.10" stroke provides adequate fluid volume for high-performance multi-piston calipers
• Ball burnished polished aluminum finish for corrosion resistance and clean appearance
• Dual fluid outputs (1/2"-20 UNF) on both sides of the bore for flexible installation
• Includes plugs and fittings for 3/8"-24, 1/2"-20, and 9/16"-18 IF brake lines
• Slotted mount flanges with 3.22" to 3.40" hole spacing bolt directly to Corvette firewall studs
• Compatible with most domestic cars and trucks from the same era

Applications:

• Direct fit for C2 Corvette (1963-1967) manual brake systems
• Optimized for use with Wilwood big brake kits
• Retrofit solution for 1963-64 drum brake cars upgrading to tandem circuit master cylinders
• Tuning option for 1965-67 factory non-power disc brake models requiring softer pedal feel with reduced effort

The compact design maintains full functionality while significantly reducing weight and improving brake system performance. Optional residual valves for drum brake applications and adjustable proportioning valves are available separately to fine-tune brake bias.

Important Note: Due to space constraints, the optional proportioning valve mounting kit (P/N 260-14248) is not compatible with C2 Corvette tandem master cylinder installations.
