Thank you for your estimate. I have an estimate for a master cylinder remove and replacement and "bleed dydraulic system" with 1qt fluid ($349.70 plus tax and enviroment fees.) Midas also recommended a brake system flush with 1qt fluid ($89.90 plus t/ef). Is the flush necessary if they "bleed hydraulic system" when the master cylinder is replaced? Bleed and flush sound like the same thing... Your response shall be appreciated.
