Hi guys.  After me and my father's trip to Williston earlier this year I noticed that my rear brake seems to be a bit 'softer', meaning you have to depress it further before it starts braking.  This didn't bother too much until I noticed the problem with the ABS.  It seems that the 'pulsing' effect is much faster and more sensitive (difficult to explain  :( ).  Also, the ABS will seem to work in a way and then releases altogether before kicking in again.  Riding without ABS at this stage is much safer in all conditions.

BTW, there are no warning lights and it seems to be only the rear brake.  Any ideas?  Low brake fluid?  Air or water in the system?  Sensors or switches?  

My uncle just paid R12000 to get his 1200gs' abs pump fixed...  Really hope this is not that big of a problem...
