How much does it cost on average to repair brakes on a car?

I hope this is a joke because of how broad of a question it is.

The short answer is: it depends on the kind of repair. For example, lets say your mass airflow sensor goes bad. After parts and labor, you may owe $400. If a wheel bearing goes bad, it may be $300. Those are fairly cheap repairs. If you ever need engine or transmission work, it'll be over $500 easily.

Next time, try asking how much it would be to fix a specific problem.
