Hi, Lots of useful stuff on this subject, from people with much more experience than my own few, no make that several, days grovelling on the floor hoping to find a way to get the air out..... But just a couple of observations, firstly I too have had a master cylinder stick with the plunger in the body. Couldn't figure out why I couldn't get fluid pumped through.... This happened on two occasions, once when it was rebuilt with new seals and one seemed perhaps a bit larger than it might have been and seemed to cause the brass piston to stick. The second was, if I recall correctly, on a car that was sitting for a long time, and I think the inactivity meant that the piston stuck when the pedal was pressed. I do remember pounding around Castle Combe in my first Fulvia and the car weaving quite a lot under braking. The next day there was absolutely no brake pedal - it went to the floor. The seals had failed in the master cylinder. On the fluid subject, I have never tried silicone, partly because I thought it must inevitably get mixed unless the system happened to be apart in any case. I can see that a system with conventional fluid will take moisture in if left for years, but does anyone know over what time span it becomes significant? I understand if the fluid is changed every couple of years it is fine, but it seems to me that it should take a long time for the water to enter the system and get through the system to a position, and in a concentration, that it can cause much corrosion. I have no idea, but am curious! Thanks
