Wilwood 1\" Bore Tandem Master Cylinder Kit — 4-Wheel Disc Brake Upgrade | VW Type 1

This kit is the professional solution for anyone running 4-wheel disc brakes or dual-caliper setups on a VW Type 1 chassis. By moving away from the standard 19mm bore to a 1" (25.4mm) master cylinder, you gain the fluid volume necessary to actuate larger performance calipers with a firm, responsive pedal feel.

Wilwood 1” Bore Tandem Master Cylinder Kit

Built with a lightweight, high-strength aluminum body, this unit features a true 50/50 dual-circuit output for maximum safety and balanced braking performance. We’ve specifically adapted this Wilwood cylinder to be a direct bolt-in for the VW Type 1 pan, eliminating the guesswork of custom mounting.

This kit offers total plumbing flexibility, allowing you to run the included reservoirs directly on the cylinder for a clean look or remote-mounted for easier access in tight builds.

Kit Highlights:

• Wilwood 1” Bore Aluminum Body: Significantly lighter than cast iron with superior heat dissipation.

• VW Type 1 Specific Adapter: Pre-fitted for a seamless installation on your pan.

• Dual Circuit Safety: 50/50 pressure split ensures braking reliability even in the event of a line failure.

• Plumbing Ready: Includes -3 AN banjo fittings and a brake switch fitting to simplify your hard-line or flex-line installation.
