Dot 3 Brake fluid. Does it matter???

Hey guys,

Want to know what dot 3 brake fluid I should use when flushing my '12? I have two bottles of DOT3 napa...is that good enough or is it ****ty? I live in the rust belt so do you think I need one with extra corrosion inhibitors? or is this good

Thanks,
Chris

DOT 3 is fine, but you can use DOT4.

here is some info on the grades.

rha600 is correct.

But if either of those bottles has been open for a while I wouldn't use it. I'd stick with fresh fluid that hasn't had the chance to pick up any moisture.

Any reason you are changing the fluid after just one year or so?

Reason isn't because of brake fade or anything. I'm mounting my 37's soon so I want to have the brakes in tip-top shape. lol. I like a stiffer feel. IDK about you but my JK brakes have never felt as stiff or responsive as my friend's lifted TJ on 33's with stock brakes.. His stops on a dime with the 33's and yet my 32's ... not so much

As mentioned, the big thing to make sure is that they're newly-opened bottles. Once you break that seal the fluid absorbs moisture which is not what you want in your lines. This is also why you should flush/bleed your brakes every couple of years.

good reason to change the fluid!

The electronic safety stuff is probably a lot of the reason the brakes feel softer.

There are some beefier brake systems you may want to look into for those 37s.

Teraflex has a bigger break kit, or you can just buy the master cylinder that gives more flow. I cannot say anything good or bad about it. I just happened to run across it doing a search awhile back.

This is the master cylinder

Then his TJ must have been a special edition. My JK on 35's stops almost as quick as my buddies LJ on 33's with blaines big brake kit. I rode in his LJ when he had stock brakes and 33's and it was scary.
