[QUOTE="RossKean, post: 1445784, member: 19880"] Yep. Front right caliper has two bleed nipples. The upper piston pair is actuated by the front brake lever but the lower piston pair is linked to the rear brake and has to be bled using the rear brake pedal. You should do that one and then re-bleed the rear caliper. You sometimes have to chase the bubbles a bit. It should take very little movement of the rear brake pedal to get solid braking action. As mcatrophy said, do a test to make sure that you can easily get sufficient braking to activate the rear ABS when riding. Find a piece of traffic-free asphalt - ideally with a little sand on it. Your rear brake pads could be "glazed" or contaminated. See if a few hard stops helps. If not (and re-bleeding doesn't help), you may want to remove and scuff up the pads with some coarse carbide paper. Wipe the rotor down with some brake cleaner on a clean cloth. [/QUOTE]
