I know Auto City can get Spectra stuff, but a little closer to town, you can try Brake and Equipment Warehouse. I haven't used them in years for stuff since we're usually on a time crunch, but they are a good source for everything brake related including master/booster rebuilds. Very good pricing on pads/rotors from what I remember.
Thier sales guy was in on Monday and I noticed thier line sheet showed Spectra brand. Spectra is good for pumps, tanks, etc.
B&E also carries Raybestos, Brembo, and even has some other machine shop services.
B&E is awsome. Ive bought a lot of parts from them. My entire brake system came from them when I went through everything front and rear back in the late 90s. Well accept for the replacement lines. They also sleeve and rebuild as well as re-shoe brake shoes.
Last time I was in there they had just re-shoed a set of brake pads for a 6 axle railroad locomotive. Talk about a major piece of brake equipment, you thought semi truck brakes were big.
