Wilwood 260-7563 Tandem Master Cylinder w/ Remote Reservoirs, 1 Inch
SKU-8352607563
                        

Tandem remote master cylinders provide one of the safest ways to actuate four wheel or dual caliper axle brake systems. This versatile, lightweight and easily adapted master cylinder provides single pushrod activation of two separate brake fluid circuits.

Shipped complete with the master cylinder and all necessary hardware including 30 inches of hose that can be cut to the desired length for remote mounting of the two 4 ounce fluid reservoirs. 

  • Can be bolted directly to Wilwood single mount pedals
  • 50/50 front/rear brake output from a 1.00" bore with 1.10" stroke
  • Great match for Wilwood's Bolt-On-Disc Brake Kit systems configured from OE components
  • Reservoirs can be either remote or master cylinder mounted
