if you car required dot 4 which is the case for newer cars, it is best to have the system bled. since the boiling point of dot three is less than dot four. this will cause stress to your entire braking system if not properly dealt with.
Dot4 fluid can be used and mixed with dot3 brake systems. If your brake system calls for dot4 fluid, you can not use dot3 fluid in the system, regardless of being only dot3 or mixed. Dot3 system = either dot3 or dot4 fluid, or a mixture of the two. Dot4 system = only dot4 fluid, and NO dot3 fluid.
Not a problem at all.Not a problem at all.
DOT3 or DOT4
Dot3 or Dot4
dot3 or dot4
Either is OK
Dot 3 or Dot 4. and if manual the clutch fluid is the same as the brake fluid (Dot3, Dot4)
Yes you can. Simply put, DOT4 is a premium version of DOT3, and they will mix. A lot of newer vehicles spec DOT4 in the brake or hydraulic clutch systems, so check to see what your specific application calls for. Quick side note: DOT5 brake fluid is the one that WILL NOT mix with DOT3 or DOT4.
The brand is not important, but look for brake fluid with Dot4 specification. This will mix happily with lower spec Dot3, which you probably have.
I believe that DOT4 is ok for DOT3 applications, but DOT3 is NOT ok for DOT4 (to remember: "big fish eat the little fish, but little fish can't eat the big fish")
According to the owner's manual, the recommended brake fluid is DOT4, and if it's not available, DOT3 can be used.
According to my local dealership here in WV, suzuki atvs take DOT3-DOT4.
