Brake Fluid
Looking for verification on proper brake fluid for my Civic (99 Si). DOT3 or DOT5? If vehicle spends some time at the track, what differences in fluid should I consider?

Re: (pdiggitydogg)
Like the other guy said, if you are using them a lot and make hard stops it might be best to move up to dot 5 ...but if you want what they rec. its dot3 good luck, which did you decide

Re: Brake Fluid (B18C1 Del Sol soon)
Don't put a dot 5 fluid in your brake system.
Dot 5 is incompatible with dot3/4/5.1. Dot 5 is silicone based and dot 3/4/5.1 are polyglycol based.
Check your owners manual. And it will probably say dot 3 or 4 only.
Just go to pep boys and compare all of the dot 4 fluids. I think valvoline is the best one they carry.

correct, no dot 5 in a dot 3/4 system.
http://www.ogracing.com carries the ate superblue and ate type 200 gold. both are excellent fluids for track and street use.

Re: Brake Fluid (speedstars03)
ok you car calls for dot3 but if you flush your whole system you can use dot 5 and you will melt your rotors before yu boil your brake fluid unless you have abs then stay away from it
unless you have abs then stay away from it

Re: (murmur9)
Excuse the technical problems there. Quick recap. Honda dealer started this confusion. After installing a Wilwood big brake kit, I started using Wilwood 570 brake fluid (complete flush). I wanted to have my brake system pressure bled before the three more track days I have this year. I took it into the dealer for this. They initially indicated DOT 5 was what I should be using. Since I was already using DOT3 (Wilwood) I was concerned. I later discovered DOT 5 was NEVER recommended for the Civic Si (99-00 at least). It's all worked out now and my brakes feel better than ever after the pressure bleed. I would highly recommend a pressure bleed over the two man pedal operation. Braking pressure feels much more linear than before. This will be HUGE for running at Road America. Thanks for responding. SS
