I had a tough time bleeding the silicone without using a pressure bleeder.

I have been using silicone fluid for years and never had a problem bleeding brakes.

I spent about 50 hours trying to bleed the rebuilt master in my 69 chevelle with silicone and everyone told me the problem was silicone fluid. What I finally figured out was the original proportioning valve located below the master cylinder was sucking in air when I released the pedal but not leaking fluid out when I depressed the pedal https://www.yenko.net/ubbthreads/imag...ns/shocked.gif. I put a new one on and had no problem bleeding. https://www.yenko.net/ubbthreads/imag...lins/smile.gif
