Brake fluid

I was going to change the fluid in my 92 and wondered if anyone had a prefrence on types. Any problems with switching to a synthetic?

Try the synthetic brake fluid. I found a big bottle of synthetic brake fluid at Walmart for pretty cheap. The synthetic should stay much more stable than the regular stuff. The synthetic brake fluid will mix ok with the regular stuff.

Big problem switching to synthetic. The two fluids are not compatable. It will cause problems with seals etc. Change the fluid often. But use a mineral based fluid.

Re: Brake fluid (Red 86 4+3)

All the synthetic brake fluids that I have seen (rated DOT3 and 4) are fully mix compatible with the regular stuff. You are probably confusing it with the silicone brake fluid (I think that's Dot 5). The silicone brake fluid will not mix at all. But the synthetic DOT3&4 brake fluid is totally mixable.

I have used the Valvoline synthetic many times. It will mix with any DOOT 3 or 4 fluid. The wet boiling point is pretty high. Another good fluid is the Ford fluid.

Motul 600 here. Outstanding boiling temps wet and dry. Not exactly cheap. Spent 25.50 for two bottles and that was enough to do front and rear.

Re: Brake fluid (Stevebra)

I just changed to a different type called Castrol heavy-duty. I think it is synthetic or partially so. My mechanic recommended it. It replaces all dot3 and dot4, but it is not the dot5. I have heard bad things about the dot5.

Changing my brake fluid made all the difference in the world for my brakes. They used to have severe fade on the track, but now they are toe touch in all conditions (except stone cold).
