A brake fluid flush or exchange runs from $70 to $150, as of 2015. The price of a flush varies widely and depends on the model and make of the vehicle.
Prices also vary among service provides; for example, Pep Boys brake fluid service starts at $70. The service includes an evaluation of the brake system and replacement of brake fluid.
During a brake flush, the service technician flushes out the old brake fluid, adds new fluid and bleeds the brakes. The technician also checks the system for leaks and examines the system’s brake pads, hoses and rotors. The technician usually test drives the car after the exchange to test for problems.
