SILICONE BRAKE FLUID

[BJCHEV396]

Don't drive my 1970 Nova as much as I should so she sits a lot--in a temperature controlled garage.Developed a master cylinder leak so I got a kit and will rebuild it.Going to flush out the system and am thinking of using silicone brake fluid.No more worries of water absorption in the fluid.Have heard both good and bad info on silicone.Any input would be appreciated.Thanks,Bill.

I have had DOT 5 in my black 69 Camaro for over 10 years and no problem with it at all. Nice brake pedal. Drive the crap out of it every summer and fall too.
Also used it in all my resto projects.

I use DOT 5 also with no issues.

I've only heard of people with Corvettes and disc brakes having problems with DOT5. Maybe something about the caliper design that traps air and makes proper bleeding impossible?
I've been running it for more years than I can remember in cars with absolutely no issues.
Just don't shake or drop the bottle before you add it, and pour it slowly. The key is to avoid any trapped air bubbles in it.

When I restored Corvettes at Corvette Specialties in the early 80's DOT 5 was all we used with no issues. Since going out on my own I have used it in 90% of my restorations. It tends to seep a little where DOT 3 likely would not but you just tighten the fittings and move on. No damage. It is very hard to do a full restoration without some spillage of fluid so I am thankful when I have had it in. Most rebuilders who resleeve the master cylinders and wheel cylinders will not warrant them if you use DOT 5 however but that is the only issue I come across.

Dont forget, if you go from Dot3 to Dot5, all seals need to be cleaned with denatured alcohol. Not fun.
