This afternoon I swapped the rear brake lever to the GSA design with the flip down beartrap. I did this since the standard GS lever felt it was engaging too low despite my adjusting it. The swap was easy, straightforward. I checked the brake was operating normally and the calipers weren't dragging. On a ride this afternoon I noticed two things : one was that the rear brake felt warmer then the fronts when I stopped for gas. I often use both F & R brakes mostly out of habit. Since the GS has linked brakes, when I use the rears am I using too much rear (thus heating the rotor too much)? Or is it possibly a by product of the smaller rotor taking more heat due to smaller surface area? The second thing I noticed was the banjo fittings were / are a light blue tint. At first I cringed, thinking I was cooking the fluid and discoloring the fittings. The rotor isnt the rainbow dark blue of a dragging brake pad, so I looked at the front fittings which are also light blue. I didn't notice this before, but the systems feel like they are operating as they should. So I guess my question is if I am using the rear brake on a GS (with linked brakes) am I using too much rear? Or is a little more heat for the rear rotor considered normal?
