Wilwood First-Generation Tandem Master Rebuild Kit, 1-1/32-inch Bore

Pistons, seals, a spring assembly and retaining ring renew the specified first-generation Wilwood tandem master. The nominal one-and-one-thirty-second-inch bore separates this kit from the visually similar one-and-one-sixteenth-inch Chrysler-style repair package. Disc brake systems and components are the focus of Wilwood Engineering's design and manufacturing work for street-performance, specialized and motorsport applications. Bill Wood founded the Camarillo, California company in 1977. Its master cylinders, calipers, fittings, valves, brake lines and rotors are chosen according to the needs of the complete brake system.

Technical Details

• Manufacturer part number: 260-2414
• Component: Cylinder rebuild/service kit; replacement housing not included
• Service bore: 1-1/32 inch
• Matching units: First-generation tandem masters 260-3261 and 260-3563

Fitment & Compatibility

Wilwood identifies masters 260-3261 and 260-3563 for this kit. Confirm that exact family and bore before opening the cylinder. The linked DS-225 currently names the later 260-4896 kit, so obtain instructions appropriate to the early master rather than assuming every illustrated part is interchangeable.
