Which Brake Fluid?

[theKnifeArtist]

which brake fluid do i use? is it dot3...dot5?
i dont know why it was so hard to find an answer in the tsrm or the search.

 

[Superjustin13]

Dot3.

 

[theKnifeArtist]

thank you.
thread finished.

Flush the whole system and switch to Motul 600.

You'll be amazed at the difference.

 

[theKnifeArtist]

thread finished..i guess not..
how much would i need? 1/2 liter?

 

[mattjk]

Ford hi perf fluid is also good.

 

[theKnifeArtist]

oh boy, here it comes, now you guys are makin me think..

 

[mattjk]

if you want cheap and safe AND good, Castrol LMA is the one to get.

BTW, unlike motor oil, you cannot mix synth and regular brake fluid.

 

[Supracentral]

One bottle is a 1/2 liter. Done properly, a full system flush usually takes about 3 bottles.

Motul isn't cheap, between $10 - 15 per bottle. But as I said, it's well worth it. It's a 100% synthetic brake fluid and has a very high boiling point.

Its dry boiling point is 593˚F, wet is 421˚F.

Pretty serious stuff.

and i wouldn't attempt a flush with an abs system unless you have the proper tools.

Get it power bled. As soon as I get my ABS system working again, Im gonna get it power bled by a local shop and have them do my own fluids.

Most likely Motul as Supracentral said

 

[mattjk]

are you going to track your car?

 

[Big Wang Bandit]

Probably when I get everything straightened out.

But to the OP, if your just DDing it, the DOT 3 never fails

 

[mattjk]

if you're going to go up to motul, do stainless braided teflon lines while you're at it. Otherwise just go for the castrol.

 

[theKnifeArtist]

fuck it, i've been pretty mad at my damn supra lately. she doesnt deserve any fancypants fluids right now. im gonna hold off and just use dot3. thanks guys

 

[Ckanderson]

Motul 600!

ATE Super Blue also rox beacuse of its color

Guys need to be careful here:

Some brake fluids (forgot the technical term) love water vapor.

Great for race cars with scheduled tear downs, bad for cars with 30,000 mile brake fluid changes.

Also, another great brake fluid is the Wilwood EXP 600 plus.

As take from their site:


EXP 600 PLUS SUPER HIGH-TEMP RACING BRAKE FLUID:

EXP 600 Plus is a highly refined blend developed for extreme performance under the high heat and extreme pressure of professional motorsports.
What’s in a number?
EXP 600 Plus has tested to 626 degrees F with a wet boiling point of 417 F. These numbers far exceed any DOT or SAE specifications.

What’s the real test?
It is true that racing fluids need to have high boiling points. It is also true that fluids need to have low moisture affinity to slow the natural absorption rate of water vapor. But the true test of any fluid is how well it resists aeration and compressibility after it has been heated and pressure cycled a few hundred times. The real test is at the track. EXP has proven to maintain firm pedal feel and quick response, long after others have failed.

Where’s the proof?
A Winston Cup car racing for 500 laps at Martinsville is the most grueling brake test in all of motorsports. The brakes will be applied up to 1,000 times, plus pit stops, at sustained high heat and repeated high pressure. IRL, CART, ASA, Busch, Craftsman Trucks, and a whole world of other oval and road course competition series also demand extreme performance from their brake systems. EXP 600 Plus has passed the test in every series!

Note:
For optimum performance, EXP 600 Plus should not be diluted with any other brake fluids. Add new fluid to a clean system.

I was about to say I'm a bit surprised everyone mentions Motul but no one says a word about Wilwood. I've run Wilwood 570 (currently) and Wilwood exp600+ in a few different cars and they are both excellent fluids.

I only mention Motul since it's the one I've got personal experience and track time with. In general I won't reccomend things that I haven't used personally.
