shit i didnt know this, and i just changed my brake fluid with reg dot 5.........i guess i got to do it again next week. what kind should i use any preferences?Seven said:word, i am going to say this. Take the DOT-5 crap out of your system, before you have a serious problem. You are going to swell the seals in the master cylander, blow them, and have no breaks at all, as well as many other problems *Dot 5 tends to bubble when you use the breaks a lot, such as stop and go traffic*. Our cars were made for DOT-3 for a reason, stick to it, and just get the high-temp version of it.
