[TR] TR6 Brakes Update

[Dave]

I was told that all fluids ARE compressible but most fluids compress so little it is of no consequence.  I guess defining a fluid as compressible is a judgement call based on the context.

Like Randall, I have had good results using DOT5 fluid with the SS braided hoses.  Rant that setup on my TR6 for almost 20 years.  It is currently disassembled due to frame issues but it will be going back together with the same set-up when I get the frame back.

I recently used some silicone brake fluid that had been sitting untouched for 2 years.  It still foamed up when I vacuumed it. 

I think the residual micro bubbles in solution are why people feel that silicone brake fluid gives a softer brake pedal than DOT3/4. 

As I recall aren't ALL fluids considered "incompressible".  If so, then if silicone gives softer brakes then it is something other than the silicone fluid that is causing it.....   Micro bubbles???

In fact that is the technique used in very high vacuum pumps.  Therefore the technique I use is to fill the master cylinder and wait a while (couple hours if possible) before I bleed.
