Wilwood O-Ring Kit - 1.25/1.12in Square Seal - 4 pk.

This kit gives you the four O-rings you need to rebuild a pair of Wilwood calipers that use a 1.25-inch and 1.12-inch square seal. Keeping your caliper seals in good shape is important for proper brake function. Worn or damaged seals can lead to leaks or sticking pistons, which affects braking performance and can even cause uneven pad wear.

These are the specific square-section O-rings designed for certain Wilwood caliper models. Using the correct seals ensures a proper fit and function, helping to maintain the integrity of your brake system. It's a straightforward replacement when you're servicing your calipers, often done when replacing brake pads or flushing the brake fluid.
