The man is talking sense .

660 isn't worth it unless you are a race team and flush/bleed every time you go to the track, and can afford the added cost.

Im not an expert my friend but i think you have to put the SS lines if you can to track your car. Today i buy mines from Z1 with the Motul Brake fluid!!! because i want to put my car ready for a track day in March.

The SS lines are mostly for pedal feel/response. Less mush in the system than having the rubber expand against the pressure. They're not strictly necessary right off the bat.

When I cooked my fluid for the first time I changed the fluid and got some confidence back. But the SS lines I got full confidence back.

Thanks guys!

FWIW, you need to be sure flush and bleed the system more often with 660. It is even more hydroscopic than 600 is. Once the water content gets above a very very low percentage, its boil point comes way way down.

Has anyone actually burst a brake line? I've never heard of it. I could see it if the lines were old and the rubber was dry and weak. But surely not a line in good shape on a well-maintained or relatively-new car?

Sh0velMan · 01-28-2014, 12:49 PM

I've never heard of anyone actually rupturing an OEM brakeline that wasn't a million years old. Could happen though I suppose.

Yup I flew off the track at pocono. I was less than 3 feet from the wall once I stopped, never been the same since

From a blown brake line? That's a serious Code Brown moment.

Your lack of swearing is absolutely remarkable.

synolimit · 01-29-2014, 08:56 AM

Never mind, just googled the difference. Well still. 23 degrees seems very low to me when we are talking about 600 degrees. I can't see a track car teetering right on that line where 23 degrees makes or "brakes" you. Get it? Brakes you? Haha

Cost aside whats wet vs dry? I mean brake fluid is wet no? Isn't that the important number to watch? Again the 600 is 1 degree better than the 660 anyways in the wet.

wstar · 01-29-2014, 09:00 AM

Wet is when the brake fluid is contaminated with water, which inevitably happens over time, unless you only run in perfectly dry conditions and low humidity and swap all the fluid just before every race weekend or something. Bleeding regularly helps, but for those not on infinite time+money budgets for swapping brake fluid the wet temp is important.
