The cost of replacing brake calipers varies wildly depending on what car you're fitting it to. For regular, road-going vehicles, a single brake caliper averages between $150 to $500. However, you should expect to pay much more than this if you drive a luxury, high-performance, or heavy-duty vehicle. For instance, a luxury car such as an Audi, BMW, or Mercedes might set you back between $800 to $1,000 (or even more) for a brake caliper replacement. That's not all, either. Once you've replaced the brake calipers, it's a good idea to swap out the brake rotors and brake pads, too. Between those two, it might cost you as much as $250 to $500 per axle (for two wheels). You can expect it to go even higher if you're using specialty brakes for sports cars or off-roaders.
