2006 BMW R1200RT Brake and ABS Bleed
RoyB:
Greetings all
I recently replaced the transmission on my 2006 BMW R1200RT which has 68,000 miles. In order to replace the transmission, the frame had to be split requiring the removal of one of the lines from the ABS Controller to the rear brake. There is now air in the system that I need to remove prior to getting the brakes to work again.
I purchased a GS911 in order to assist me in the bleeding process, but find that the Whizzy Brakes on this model may or may not require the use of the GS911. My question is as follows:
I need to get the air out of the rear line from the ABS to the rear caliper.
How do I bleed the line if the ABS cannot be powered up? Is this a simple matter of bleeding the caliper and refreshing the brake fluid level in the ABS Reservoir or is there more to this?
Thanks

Just had a look on the Function Chart for your R1200:

Thanks Mike. The link you provided outlines the ABS 2 found in 2007 and later bikes, not my 2006.
iabs2can
Found in models:
The 2nd generation integral ABS, first introduced in Q4 of 2007. This generation, unlike the first is not servo assisted, and is found on most R1200 (K2x) and most K1200 and K1300 (K4x) models.

Thanks Mike
In looking at the document, everything looks good until Page 8, item number 20 where the instructions outline turning on the Key to allow the ABS to initialize. I will go through the bleeding process to see if this happens after removing the air from the rear brake. I have a MityVac as well as a bleeding solution that uses an air compressor to create a vacuum to pull the fluid from the lines.
