Why can I just use time or mileage to perform brake fluid service?
The type of driving, like highway or “stop-and-go”, hides the secrets that time or mileage won’t discover. And GM, Ford and Chrysler don’t have a recommendation for brake fluid service. If the vehicle has O.E. (BMW, Mercedes…) brake fluid recommended maintenance based on time/mileage, you can offer brake fluid replacement according to the O.E. parameters. Many shops and dealerships still use Brake Strip because it will help clarify service within maintenance parameters.
