brake fluid

The one thing you really need to be aware of when it comes to silicone brake fluids is they outgas. Unlike a DOT 3 or 4 which have a propensity to absorb water, Silicone brake fluids like air, and what happens when you drive over the mountains...........the air in the fluid out gasses due to the different atmopheric pressures and VOLA you have air in your brakes and pedals that may go to the floorboards.
