How to install BC ABS BRAKE LINE on the Bonneville and Street Series


The how-to guide is proved for information purposes only. The guide assumes you have general mechanical knowledge and have the ability to remove and replace components on your motorcycle. Contact a professional mechanic if you have any questions or are not comfortable doing the work. Keep all stock parts from your existing system as some components may be necessary to install your new British Customs Products, depending on the application. 

Read through the guide before beginning to remove any components.  Always correctly support the vehicle with a stand and/or lift when servicing or performing any work. Unstable vehicles may present dangerous conditions and cause property damage and/or personal injury.
