Hello. I need new calipers on my 04 Grand Prix and I found on e-bay calipers by Callahan. Now I would buy them from Tommy Boy himself, but anyone else, I'm not sure. After some research, I did find that they are a division of Powerstop brakes, which I have heard of and used their ceramic pads on my 99 Dodge Ram with no problems. Anyone out there every give the Callahan brand a chance? I'm just getting the hardware, no pads. They are already powder coated red, which I thought was kinda cool. Thanks for any input.![]()
