Go look on priuschat if you want more info on the brake flushes. I have an '07 Prius (same generation) with 120 kmiles and the brake fluid looks absolutely pristine. This causes brake fluid to last quite long. As a result, the brakes are actually used very little. The car tries to capture as much energy and put it back into the battery as possible. You need the dealer computer to control the valves to actually get it to release fluid.Ģ) The brake fluid almost never sees elevated temperatures (because of the regenerative braking). There is a stroke simulator and lots of various computer controlled valves on that system. The brake pedal is used to control the computer (for regenerative braking) before it actually puts on the brakes. There are two very good reasons for this:ġ) Because it's a hybrid, the Prius braking system is NOTHING like a typical braking system.

Please, unless you fully understand what you're doing, DON'T try to do a brake fluid flush. It will probably turn into a brake flush.
