Quora User, I have been working on and racing cars my entire adult life. You can expect most shops and dealerships to charge between 40% and 80% over retail value for the cost of the parts, plus $50-$60/hour for labor costs. This generally works out to a total cost between $300 and $400 for the replacement job. This value can be considerably higher if you are using performance rotors, or if the replacement is being done for a high-end vehicle at a dealership.
