Hi guys,
I know this topic has been hashed & rehashed, but I need to ask more questions...
1) I know that DOT 5 silicone is off limits.
2) I know that DOT 3 is recommended for the clutch, and it is what I flushed that system with a few weeks ago in an emergency type situation when it boiled.
Now, I am preparing to flush & fill the brake system. I don't know what I've got now, but I assume it's probably DOT 3. (John, if you read this, can you tell me what you used in the car?)
So, my question is this: where does DOT 4 fall in this scheme of things?
Specifically, I've picked up a couple of bottles of Valvoline SynPower "Synthetic Formula" that says "Exceeds DOT 3 & DOT 4." The label then says it is "compatible with conventional brake fluids," and on the back it is called "SYNPOWER ABS synthetic DOT 3 & DOT 4 motor vehicle brake fluid."
Has anyone had experience with this stuff? I intend to run it through the system till I have fresh fluid coming out all the bleeders, but I don't want to destroy any seals or gum up any pistons, etc. Is anyone running it successfully in Wilwood components? Has anyone introduced it into a system (without incident) that previously held straight DOT 3?
Thanks for the help - I guess I'm just a little nervy about doing anything concerning brakes. Especially right now, since making a big mess would ground the car for the Pigeon Forge weekend.
