Thanks!
When I was spinning the rotors, checking for caliper bracket clearance, I heard a slight "ball bearing" noise. I took it for a 2 mile brake and rotor bedding run, and could hear the noise in the car. It was audible over the exhaust. I was so mad, I just parked it, and didn't even look at it for 2 days. I knew what was wrong and ordered new hubs, bolts, and dust caps. I bought the SN95 spindles/hubs used, and could not hear anything until I spun it with the rotor on.
Took it apart a couple days ago, and this is probably the culprit.
(hard to get a good photo, but the black pen marks the spots)
New hubs arrive tomorrow, minor adjustment on the booster push rod, re-bleed the system, adjust rear bias, and the forecast is rain all weekend........hahahahahaha
