After installing all new brake lines, wheel cylinders, flex hoses and a master cylinder, I am ready to add silicone brake fluid. I have never bled a completely dry brake system before as well as used silicone brake fluid in it. I plan on using a pressure bleeder attached to the M/C. Any suggestions, tips or warnings would be appreciated. Thanks

i personally would not use the silicone fluid the reason is it swells the china made cups and cause the brakes to lock up . not only me but several other chevy owners it sounds like the thing to do no moister the cylinders looked real good no pitting new major brands but could hardly drive the cups out seems to work well with the regular dot 3 fluid maybe some of the others that have tried it will comment hope this helps

I had no problems with the silcone fluid other than screwing--up the hydraulic stop light switch on my '39. Also safe to use as it does not remove paint.

Thanks for the comments and information. Back to my other question on a completely DRY system. Other than keeping an eye on the M/C reservoir, should anything special be done?

The major problem with silicone fluid is air. It tends to hold air bubbles more than conventional. So minimizing air entrapment or entrainment is critical. Fill the master cylinder and then take time to let any air bubbles dissipate before pushing it into the lines. Pressure bleeding will help if all the air is out. Can be a frustrating problem if not.

Thanks Chipper for your information. I hope to start bleeding the system this weekend.
