I bought a 2011 2 months ago and trailered it home. The rear (ABS) brakes felt a little spongy and the fluid was a bit dark, so I bled them today. The fronts are great, but no improvement on the rear brake pedal. I have not ridden it as I'm in the process of checking the values soon too. I followed the instruction in the service manually, going from front to back twice. The fluid is running clear and bubble free. When I depress the pedal it initially goes down about 1 1/2 - 2 inches, stops, then slowly drops another 3-4 inches with constant pressure applied. Is this normal? Thanks, Mark
