I asked that question of Master Power Brakes Salesman and got a non-answer. He skirted the issue. I asked because they state in their literature that if you use DOT 5, it will void their product warranty on the Power Brake Booster system that they sell.I invite everyones's comments    Dick Palmer

Re silicon brake fluid.  Many years ago at Ford and involved in a torque converter shudder issue.  One of the team members was a tribologist/fluid specialist.  He was there a long time and involved with the various transmission fluids, among other things.  I asked him why silicone brake fluid wasn't being used as the brake system wouldn't corrode, ... .  He indicated, that it is not hygroscopic and that depending on temperature, water in the system can freeze and could result in brake failure.  Being vehicles are sold to the general public, all factors have to be considered.

I got to wondering (as I frequently do) about the military's fascination with DOT 5 fluid.

Read through this thread, especially POST #8.
