What brake fluid do you recomend

[dodge68charger]

Gonna bench bleed my master cylinder and bleed my brakes. What Dot brake fluid should i use in my system. I have front discs and rear drums. Thanks

Same question. 11" drums all the way around. What is best? Synthetic ok or is there such a thing.

I use DOT 3, for a few reasons. Silicone based (dot 5) compresses. Leaving a spongy pedal. Though supposedly backward compatible, dot 4 contains different chemicals, which may or may not react with the seals in our cars. I won't get into a discussion about brands. I'm sure many opinions are out there...

I've always used DOT 3, although you can use 4... 4 has a higher temperature boiling point. Do not use 5 silicone-based. As long as the fluid is new, or flushed periodically, as you do coolant or oil, it's fine.

motul is supposed to be a high performance fluid.... don't know but something about the boiling point and retaining viscosity?

I use DOT 3.

Here's Pat Goss from the TV show Motor Week about brake fluid choices.
