I believe my driver's side front brake caliper needs to be replaced. I can tell that its grabbing the rotor but for some reason it doesn't do it constantly. It will do it for a while and then go away. I can tell its been doing this when I get to my destination and I can feel the front driver's side wheel is warm but the other wheels are not. My car has 125K miles on it. Do the brake calipers go bad on the 850's at around this mileage? Its annoying and I believe to be dangerous. But like I said its not constant. Should I go ahead and replace both front calipers anyway just to be sure? I'd hate to do this only to find out that its not the calipers that have a problem. It couldn't be the ABS computer doing this, can it? No codes have been showing up at all. Thanks.
