Wilwood 260-14957-P Compact Tandem Master Cylinder Bore with Pushrod - 7/8

The Wilwood 260-14957-P Compact Tandem Master Cylinder is engineered for manual brake applications requiring precise pedal feel and reliable hydraulic performance. This master cylinder features a 7/8" bore diameter with a ball burnished finish and includes a 3/8-24 diameter pushrod for direct integration with manual brake systems.

Key Features:

• 7/8" bore diameter for optimized brake pressure and pedal ratio
• Ball burnished aluminum finish for corrosion resistance and clean appearance
• Includes 3/8-24 threaded pushrod for manual brake pedal mounting
• Dual fluid outlet ports on both sides of bore for flexible installation
• 1.10" stroke length with 2:1 volume ratio between primary and secondary chambers
• Fits mount flanges from 3.22" to 3.40" (compatible with most domestic vehicles mid-1960s to present)
• High-pressure die-cast aluminum construction weighs only 3 lbs (75% lighter than cast iron OE masters)

This compact tandem master cylinder is designed for retrofit applications where weight savings and performance are priorities. The dual-chamber design provides split braking system safety, while the lightweight aluminum construction reduces unsprung weight. Wilwood offers compatible proportioning valve kits with brackets and stainless lines (PN 260-14248 for left-hand outlets or 260-15667 for right-hand outlets) for complete brake system integration.
