Frequently Asked Questions

What are the front brake hose length and connection?

One hose measuring 15 inches is included for the front master cylinder to the three-way joint position and replaces Honda OEM 45126-300-003.

Are the other brake hoses and sealing hardware included?

No. Other hoses, pipes, junctions, banjo bolts and sealing washers are separate. Use new sealing washers wherever the Honda procedure requires them.

What must be checked after installing the brake hose?

Route it without twists or contact through full steering and suspension travel, fill and bleed with the specified brake fluid, then hold firm pressure while checking every connection for leakage before riding.
