Thanks I have done everything else doing cooling and trans fluid differential's I did transfer case power steering brake fluid and flushed out the trans fluid from the converter and the linesThe recommended intervals for changing brake fluid are all over the board depending on the manufacturer, from as often as every two years to actually never. Wait, never? Really, never.
For example, Chevrolet calls for a brake fluid change on most models every 45,000 miles, but Honda says to do it every three years regardless of the vehicle’s mileage. Three years is also the recommended interval for most Volkswagens, but Mercedes-Benz vehicles typically call for fresh fluid every two years or 20,000 miles. In contrast, on the Ford Escape, Hyundai Elantra, Toyota Camry and other models from those manufacturers, there are no recommendations for replacing the brake fluid, only instructions to inspect it periodically.
my book calls for differential oil every 32k
And transmission oil every 60K towing or hard use, to 120k reg use.
No mention of changing the brake fluid.
