Description
Wilwood brake calipers demand precision sealing to maintain consistent stopping power and prevent fluid weeping that compromises safety. This square O-ring kit provides factory-spec replacement seals for 1.25-inch pistons, keeping your calipers functioning at peak efficiency without the need for full caliper replacement. The 4-pack gives you coverage for multiple calipers or spares on hand for future maintenance intervals.
Built from 210M elastomer material, these seals are formulated to resist degradation across DOT 3, 4, and 5 brake fluids while maintaining their ability to promote smooth, unrestricted piston travel. Whether you’re maintaining a road course car or a weekend warrior, preventive seal replacement ensures your braking system remains leak-free and reliable.
