Calipers are on correct sides (niples on top). Had tire/perfromance shop flush fluid last year replacing Motul 600 with Motul 5.1. 5.1 is thinner and supposedly works better with ABS systems. Also doesn't absorb water as quickly so doesn't need to be flushed as often. Shop said they did not have to bleed the ABS unit. I will do the full two-man bleed procedure this weekend including ABS and see if this has an impact. If not must be master cyclinder bias valve.
