The use of silicone fluid should be avoided for several reasons. Among them, it is virtually impossible to completely bleed the system of air, as well as the fact that the fluid WILL attack seals. I prefer a dot 4 low mositure absorbing fluid, especially Castrol LMA. This fluid is especially good for vehicles in damp climates or ones that are not driven regularly. The reason is your cast iron brake parts are pourous, and WILL absorb water to the extent that the system will have problems that could lead to failure at the most inopertune time. regards, L.
