I am at 35,000 miles on the Prius and am ready to do a brake fluid flush with Techstream. There are various posts throughout the web of people using the low-viscosity DOT 4 fluids, such as ATE SL.6 and Pentosin DOT 4 LV, in place of traditional brake fluids in applications where low-viscosity fluids are not mandatory. Some of the benefits reported include smoother ABS cycling and different cold temperature brake feel.
However, the Prius braking system sees very little thermal cycling and use, so high-temperature performance is not the most important concern. Also, regenerative braking is always used to some degree, so I am curious how this would change with a low-viscosity fluid.
The low-viscosity fluid will cost $15-$20/qt, but the price is not a concern. What I am curious about though, is what differences have you folks noticed with a low-viscosity brake fluid in traditional brake applications.
Thanks.
