Bleeding Brakes on R1150RS

[mgr1001]

Looking for advice on the proper procedure for bleeding the brakes on an 04 R1150RS with partially integrated ABS.

I just replaced the front brake line (from the handlebar lever) with a longer one because I installed a set of bar backs.

Tried bleeding the brakes myself with no luck. There seems to be a lot of residual air in the system. Is there a special tool required?

Any advice would be appreciated.

There is a special tool required to properly fill the system.
My local MacPac member have made one such tool to bleed EVO intergrated brake system recently. I'm looking to change the fluids in my 02 R1150RS next month.
I will try and dig up old emails about the specific tool and forward them to you.
