Lee You can just bleed it through, and replace nothing unless it needs replacing anyway. Now would be a great time to inspect every thing & replace items in question. Make sure you do a though job of bleeding as it tends to turn the petroleum based fluid into mud down the road if you did not get it all out. A power bleeder is the best way if you have access to one and make sure the fluid coming out is clean, that way you should not have any residual old fluid. But if you experience that, I just clean the mud out with a clean cloth and rebleed till you get the blue or red fluid flowing clean!. The only advantage you would gain is corrosion proofing and that ant all bad at all!! The petroleum based fluid can absorb moisture causing lines to corrode from with in over time, the silicone will not absorb moisture and that's a good thing! The other advantage is brake heat dissipation from repeated hard applications that is probably not the way you are driving your car. Now if you are experiencing brake fade do to heat then you will notice a difference. The question I guess is it worth the extra cost converting over? Or if it ain't broke don't fix it?

What are your opinions on using silicone brake fluid instaed of regular Fluid in our cars? Do you have to replace all of the hoses and Cylinders, etc? Or can you just bleed the silicone fluid through the Wheel cylinders? Thanks Lee Sumpter 64 Fury ---- Please address private mail -- mail of interest to only one person -- directly to that person.
