Default Re: Brake Fluid

I found that dot 4 is better than dot 3. This was a durability test on clutch slave cylinders on a rig. The cylinders were failing, a switch to dot 4 made them pass the test ok.

I've used dot 4 on everything ever since. I have dabbled with silicone, but the last car I have that was silicone is now on dot 4 after a brake overhaul a couple of years ago.
