I had the same issues breaking in some Axxis pads in SF. Went to the MacArthur tunnel in the Presidio, and then the roads in South San Francisco, below Cesar Chavez along 101 (on the west side of 101, not Hunters Pt!).Any one live in San Francisco have any suggestions on a good location to bed new brake pads? I've been reading the bedding instructions at Zeckhausen site and I sounds like I need a like a highway...sort of a rare thing in the City. Great Highway perhaps?
