What does a banjo bolt do on a caliper?

A banjo bolt is a specialized fastener used in brake calipers to connect the brake line to the caliper itself. It features a hollow design that allows brake fluid to flow through it, ensuring proper hydraulic pressure is maintained when the brakes are applied. The banjo bolt typically has a washer on each side to prevent leaks and is crucial for the effective operation of the braking system. Its design allows for flexibility in routing the brake line while maintaining a secure connection.
