Hope V4/E4 Bore Cap

No, this specific bore cap is designed exclusively for Hope V4 and E4 hydraulic disc brake calipers. It will not fit other Hope models or calipers from different manufacturers.

You will need a specific bore cap tool or a correctly sized socket to remove and install the cap without damaging the finish or the seal. Ensure you have the proper tool on hand to avoid stripping the threads or marring the anodized surface.

This product is the bore cap itself. While it is engineered for a precise fit, we recommend checking your existing O-ring for wear or damage and replacing it if necessary to ensure a leak-free seal.

The anodized blue finish is primarily for aesthetics, allowing you to customize the look of your brake system. However, the anodization process also provides a durable, corrosion-resistant layer that helps protect the aluminum from the elements.

You generally do not need to replace the bore caps during a standard bleed unless they show signs of damage, corrosion, or if the threads have become compromised. They are typically replaced only when maintenance requires their removal and the original cap is worn or damaged.
