Or will I need to flush the system with a cleaner to get rid of this silicone? Also, anyone tried this newly advertised Power Bleeder by Motive Products. Check out their website, what you think? Looks like a very neat product. www.motiveproducts.com Thanks | | |

why do you want to change it out? silicone has some nice advantages over standard fluid, namely nonhygroscopic (doesn't suck up water)
i made a pressure bleeder too, i'm trying to figure out how to make it work on my 52. it's the easiest way to bleed brakes i've seen. | | |

You might want to read more before you go to the effort - check out Brake Handbook by Fred Puhn. The book talks about the different type of fluids and the advantages / disadvantages of each. Fred's a Professional Engineer.

To do it right all componets, lines included should be taken taken apart and cleaned when going one way or the other. About the only time you don't want to do use dot5 is in racing. They will tend to get spungy when pressed to the limit. Other than that, I have not heard of a problem with it.
