whats the best way to flush some of my parts I will be re-using during my resto? The master and wheel cylinders have less than 2000 miles on them. also if I remember the calipers are pretty fresh.




Flush them out with alcohol. You can also use some DOT5 to flush it out as well.

In response to the original inquiry, you would have to be just plain silly to use anything but silicone in a freshly restored car. I can show you countless photos of beautiful cars that had the paint destroyed by the DOT3. All of the so called maladies?? well, 25 years of using the stuff, never had a single issue. Spongy pedal?? Unless there was trapped air, frankly it's impossible. It will create tiny bubbles if you shake the bottle or really agitate the fluid while bleeding, but normally they will make their way to the top of the master and not cause any issues.

I'd recommend against using alcohol, it can damage seals, I'd just use some DOT 5 to flush but don't get carried away, even if there is still some traces of regular DOT3/4 in your system it won't cause any problems.
