The caliper slides on the girling calipers tend to seize up as water and crud get past the lillte boots on the slides. When this happens you only get one pad per caliper working and a pedal that goes almost to the floor before you get any stopping. This is something that happens quite frequently here in New England. I've had both, and from a pad replacement stand point, I think I like the bendix better, only one bolt per caliper to pull.
