1.125in Rebuild Kit

The 1.125in Rebuild Kit (WIL260-3884) from Wilwood is engineered for brake system maintenance and restoration, specifically designed for technicians and vehicle enthusiasts performing caliper overhauls or brake repairs. Whether you're rebuilding a performance braking system after extended track use or restoring factory brakes to original specifications, this kit supplies the essential seals, springs, and internal components needed to return your brake calipers to OEM functionality. Proper brake maintenance is critical for safety and consistent stopping power, making quality rebuild kits indispensable for any serious vehicle modification or restoration project.

Wilwood's 1.125-inch rebuild kit contains precision-engineered internal components including piston seals, dust boots, springs, and retaining hardware manufactured to exacting tolerances. The 1.125-inch bore dimension indicates this kit is compatible with Wilwood calipers in that size range, commonly found in single-piston or lightweight racing applications. Each component is manufactured from high-quality elastomer and stainless materials to resist brake fluid degradation, heat cycling, and corrosion. The compact kit weighs just 0.4 lbs and fits in a small footprint (2.95 x 1.4 x 7.3 inches), making it easy to store in your shop or service toolkit while maintaining all necessary parts for a complete caliper restoration.

This rebuild kit is ideal for mechanics and DIY builders maintaining Wilwood brake systems on track vehicles, street performance cars, and vintage restorations where brake reliability is non-negotiable. Installation requires basic caliper removal and disassembly; refer to your vehicle's brake service manual or Wilwood's technical documentation for proper application. Before ordering, verify your caliper bore size matches the 1.125-inch specification to ensure compatibility. Regular brake system maintenance using genuine Wilwood rebuild kits extends caliper life, prevents fluid contamination, and maintains the pedal feel and responsiveness expected from a quality braking platform.
