How Much Brake Fluid Do I Need to Flush/Fill My Car?
That's a great question and one we get all the time. If you will be doing your own fluid flush/fill and you will be changing from another fluid to RT700, we recommend purchasing 3 bottles. A typical automotive brake system with ABS has approximately 500-750mL of brake fluid in it. An experienced mechanic can typically perform a flush/fill with just 1 liter (2 bottles) of RT700 brake fluid. However, most of us are not quite as skilled or experienced as the technician doing it 40 hours a week. You would hate to be almost done with doing your flush/fill and run out of RT700 just before you finished topping off the reservoir. So even if you are pretty certain you can do the flush/fill with just 2 bottles, grab a 3rd just in case.
