  • Brake fluid

    After replacing or rebuilding the entire brake system on my 63 hawk, I now read an article in hemmings touting the value of silicon brake fluid, Anyone have any experience with the stuff or Am I just out of the loop? Everything I read says Dot 3 brake fluid . Any thoughts?
    Thanks

      I've used the silicon fluid in several of my Studes with no problems
      (eg) premature brake light switch failure.It does not absorb moisture
      so cylinder rust from sitting is less likely.A bit on the expensive side but worth the expense if you are going to keep the car.

              I endorse everything Gary Ash said. I have used silicone brake fluid in several of my collector cars for more than 20 years with absolutely no problems. The metal parts don't rust, and the fluid doesn't get muddy. If you have rebuilt the entire system, I would recommend filling it with silicone fluid, especially if the car is driven infrequently. Otherwise, stick with what you've been using. Rubber parts like brake hoses and wheel cylinder cups apparently don't take kindly to being exposed to different fluids.

              There have been a number or reports that the brake light switches used on Studes and other cars of that era tend to fail more frequently with silicone fluid. I have not had that experience.

                The stop light switches that are compatable with DOT-5, can be had at your local Harley Davidson M/C parts counter. They are a little pricey, but name something from H/D that isn't.

                  Since redoing my brakes, that had jelled w/ DOT3 a number of years ago I have used DOT5 in my R1 Hawk with no problems except the light switch once. I got a new one from Ron Francis that sells a DOT5 compatible one. Good pedal feel and no jelling and screwed up calipers/pistons.

                    I ditto what Skip Lackie says about Silicone Fluid. I put it in my '50 Starlight Coupe in '94 when I installed new lines, hoses, master & wheel cylinders. 7,000 miles later, no problems and no brake light switch problem either. I bought a '64 GT R1 Hawk last May and am not going to convert to Silicone unless I plan to replace all fluid components (not in my immediate plans). Just my 2 cents worth.

                          Be careful here when talking about synthetic, and silicone brake fluid.

                          Yes, synthetic DOT-3 and DOT-4 is compatible with non-synthetic DOT-3 and DOT4, but it is NOT compatible with DOT-5 (silicone) brake fluid.

                          Some interesting reading is here:

                            Thanks for catching that .. I was answering two separate questions at
                            work (sneaking it in) and I failed to break them up better. Synthetic
                            is not compatible with silicone. Synthetic is a better alternative
                            then going with Silicone, since it has the benefits of Silicone, but
                            not the drawbacks (stop light swtiches). If you choose to go with a
                            Silicone blend, then if you have a swinging pedal Studie, the change
                            to an electric switch is quite simple.

                              I have used all three DOT 3, 4, and 5. In my Studes since I drive them regularily I use DOT 3 or 4 but for my nephew in his 68 Cougar I used DOT 5 simply because I knew that it was only going to be driven occasionally and hard on those occasions.

                              In any case when I rebuild brakes I apply silglide liberally. I am still driving with brakes that I did some twenty years ago due to the fact that I use liberal amounts of Silglide and it keeps the rubber parts pliable and the wheel cyllinders from rusting internally.

                              So for a daily driver I would not use DOT 5 but for a trailer queen you bet.
