I would do some research on brake fluids before choosing one.After seeing the pros & cons you might feel informed enough to make your own decision.One of the difference in DOT 3 & DOT 4 is the boiling point.DOT 5 has a higher boiling point but needs more maintenance .DOT 3 & 4 both will absorb moisture and keep it in suspension.DOT 5 will not absorb moisture or keep it in suspension.Moisture in DOT 5 will seek the lowest level.DOT 3 & 4 will turn from an almost clear to dark brown and should be replaced.
The darker the color the more moisture in the liquid.DOT 5 will not change color the same way.If the brake fluid (DOT 5) has moisture it will accumulate at the lowest level .The brakes being hot can boil the moisture.The steam does not compress as good as the liquid. GOOGLE DOT 3,4,& 5 . Each have advantages . Good luck lee34
