Bleeding the brakes by activating the ABS pump and energizing the solenoids is nothing new to me as an auto technician, and I have diagnostic platforms and software to perform the power bleed on modern car and truck ABS systems. Unfortunately, it's not as easy on most motorcycles as there really isn't a widespread standardized communication protocol and the data connectors and cables are proprietary.
My Triumph Bonneville T120 is an exception. It has a multi pin DLC which I can plug an OBD2 Bluetooth adapter into and pair it with my android phone running a TuneEcu app. This allows me to retrieve and clear fault codes, reset the maintenance indicator "wrench" symbol on the clocks, synchronize the throttle bodies, and perform a power bleed of the ABS system.
I wish this was available for my CB1100. Purchasing the factory service tools, software and diagnostic platform is cost prohibitive to say the least.
Interesting. I got my CB1100 back on the road after storing it in my garage for about 3 years. A few times early on I was a little startled when I would squeeze the front brake lever, feel a lot of resistance but get NO front brake actuation. It only happened about 3 times sporadically on the first few rides.
