Caliper Shim 10pk .015in 7/16in Hole

The Wilwood Caliper Shim 10-pack .015in 7/16in Hole (Part Number 240-4387) is a precision brake component engineered to maintain proper clearance and alignment in disc brake caliper assemblies. These steel shims compensate for manufacturing tolerances and wear patterns that develop during service, ensuring consistent pad-to-rotor contact and eliminating brake noise and uneven wear. A 10-pack provides sufficient inventory for a full vehicle service or to maintain spares for multiple brake jobs.

Each shim features a 7/16-inch mounting hole, designed to fit within standard Wilwood caliper configurations. The .015-inch thickness represents a critical precision specification—shim stacking is a fundamental tuning method in brake system optimization, allowing technicians to dial in exact rotor-to-pad spacing. Steel construction provides durability and thermal stability under the extreme heat cycling that occurs during repeated braking events.

This product is essential for brake system technicians, performance automotive enthusiasts, and shops that service Wilwood brake systems on street, track, or marine applications. Wilwood brake packages are widely used in hot rod builds, off-road vehicles, and high-performance road cars where factory brake geometry has been modified. Maintaining proper shim clearance is crucial for optimal braking performance.
