Linked vs. Non-Linked Brake Schematics

( ST1300 )

The Dual Combined Brake System (DCBS) that Honda employed for the ST1300 is an effective, marvelous, and complex example of hydraulic/mechanical design. Unfortunately due to a dearth of easily accessible information for this design, a comprehensive understanding of the operation of the DCBS has remained elusive.

However this is changing, with the availability of low cost DCBS components on eBay, I have purchased, disassembled, measured, and drawn most (if not all) of the brake components for the Honda ST1300. With each component now carefully documented, it became an interesting task to try and puzzle out (reverse engineer) what the original designers were trying to accomplish.

Below are the links to the various brake components that I have documented, please note that the descriptions of operation with each component (probably on the order of 90% correct) are based on my interpretations of the hydraulic/mechanical design.

Components of Honda DCBS (pdf)
This drawing is again an over view of the DCBS with a focus on the individual brake components, and how they interact with one another.

Lastly, here's a link to more motorcycle drawings.
These are drawings that I've made relating to either my '06 Honda ST1300/A, or my daughter's '07 Kawasaki 250R.

My goal in this undertaking is to provide a resource for other curious Honda (and non Honda) motorcycle owners who just "want to know".

Cheers.
