Rebuild Kit Tandem M/C 1.00in Bore

The Wilwood Rebuild Kit Tandem M/C 1.00in Bore (MPN 260-13366) is a complete master cylinder maintenance solution designed for street and performance vehicles equipped with dual-circuit hydraulic brake systems. This rebuild kit exists to restore original feel and braking response without requiring expensive replacement of the entire master cylinder assembly. Whether you're maintaining daily driver brakes or refurbishing a project car's hydraulic architecture, this tandem master cylinder kit delivers the seals, piston components, and snap rings necessary to return your brake system to factory specifications.

The 1.00-inch bore diameter positions this kit for mid-range brake line pressure applications, making it suitable for vehicles requiring balanced hydraulic force distribution across front and rear circuits. Inside the kit you'll find precision-machined pistons, OEM-grade elastomer seals engineered to resist DOT brake fluid degradation, and stainless steel snap rings that lock components securely in place. The rebuild approach eliminates the need for full master cylinder replacement, preserving the original casting while renewing critical wear surfaces and sealing surfaces. Proper piston and seal installation ensures zero internal leakage, restoring firm pedal feel and eliminating the soft, spongy brake response that signals worn internals.

Mechanics and brake specialists reach for Wilwood rebuild kits when addressing brake system maintenance on vehicles that have accumulated mileage or sat idle for extended periods. This kit is ideal for custom brake system builds, vintage muscle car restoration, and any application where preserving original master cylinder housings makes sense from a cost or authenticity perspective. Installation requires basic mechanical skill and familiarity with hydraulic brake system assembly; the compact 2.9 x 1.35 x 7.3-inch kit contains all internal components needed for a complete restoration, though the master cylinder itself must be removed from the vehicle prior to disassembly and rebuild.
