The estimated cost of brake calipers is about $300 for a pair, as of April 2015. However, just because one shop tells a person to get new brake calipers, that doesn't necessarily mean the calipers are needed.
Some mechanics recommend new brake calipers, but an individual may find the real issue is needing new caliper pins. These pins cost only about $20, and they can keep the calipers working correctly for up to 40,000 miles of driving. Also, if calipers are definitely needed, some of them can be reused. Therefore, it may be possible to utilize used calipers instead of installing brand new calipers, which can help to save money.
