(San Francisco service?) Break Cable sticks tire replaced

[JazJon]

Does anyone know who can service my A-Bike in the San Francisco bay area? I had the tire replaced at a local San Francisco bike shop, but they are unable to adjust my breaks properly. The cable seems to catch a bit, causing the back breaks to drag/clamp down slighly. I have to manually push the cable back or squeeze the break a few times in/out to get it to release fully. I can ship this somewhere if I need to as well but hopefully someone in the bay area has a shop with a-bike experience.
