Silicone Brake Fluid

[Cockroach]

As the original owner of a 68 Roadrunner, and reading many posts over the years......some very accurate, some not so much, I decided to join and share my 57 years of experience of driving and maintaining my 68 Roadrunner. I'm going to start with the use of Silicone Brake Fluid, as there seems to be some confusion as to Silicone Brake Fluid's effectiveness. 45 years ago, I converted my 68 Roadrunner to Silicone Brake Fluid; Since doing this, I have not had a single issue: no hydraulic issues, no soft pedal issues, no ruined paint issues from spillage, and the fact that the US Military utilizes Silicone Brake Fluid, quite frankly has me puzzled, as to why more old Mopar Muscle Car Owners, are not embracing Silicone Brake Fluid, as I have for the last, almost half Century!? 5 years ago, I decided to flush my 40 year old Silicone Brake Fluid, and the old fluid flushed out clean, and un-contaminated..... the only change was the purple dye, that is added to Dot 5 Silicone Brake Fluid had faded, and the Silicone Brake Fluid was about the same color as traditional brake fluid. Which is normal, based on other blogs on-line. So what are YOU waiting for; Flush out your old traditional brake fluid (COMPLETELY), put Silicone Brake Fluid in, and never have to touch your Brake Hydraulics for the next 50 years!!

Welcome to FBBO. I converted my car to Dot 5 brake fluid and I plan on doing the same for all eventually.

Welcome Cucaracha!

I've been using dot 5 for 6 years now. Fluid in the master cylinder is still as clean as it came out of the bottle and still purple.

I used all Dot5 also.. lost it's purple fast but it's nice to not destroy paint.. and i got tons of it in my engine bay (pressure bleeder leaked) and just wipe it up

BTW... i thought that if you put dot5 in a system that had normal fluid it will destroy any seals/rubber, even if you drain the system it still has enough to cause a reaction?

That is correct, they do not mix. Dot 5 also does not work with abs.
I just replaced everything on my 66 Coronet, stainless lines, wheel cylinders, converted to disc up front, so new calipers and also converted to power disc, so new master cylinder. Other than being very expensive, it is all positives for me as well so far.

Bit of extra work flushing & bleeding but 2 years now without any issue

Switching to DOT 5 makes sense if you are trying to protect your paint from spills.
You sure pay for it though....the stuff I've used is right near $40 a quart!

I guess I am just lucky, I have never spilled BF and ruined my paint.

No thanks! All normal manufacturers run dot 3/4. For multiple reasons.
