My brake wear sensor tripped on Monday, so I will be changing pads and rotors this weekend. The problem is, I don't have any fluid. I don't want to buy crap fluid from autozone, but I'm not sure I can get anything shipped to me by Friday. I stopped by a local speed shop, and all they had was Prestone, and Wilwood Hi-Temp 570. Something to that effect was on the bottle. Both are DOT 3.

Does anyone have experience with this Wilwood fluid? I would imagine it is good enough to put in their systems, so it is probably good enough. I know a lot of people rave about ATE Super Blue, but I'm fairly certain that is nowhere to be found in my area.

Thanks

 

The Wilwood fluid is good.

For what it's worth, I've given up on the ATE fluid. I can't prove it, but I think it may damage seals over time, at least the superblue (the clear stuff, type 200, which is the same as the superblue but without the dye, seems ok).

I use Motul for the track, and I've used the Wilwood off season.

 

Great. Thanks a lot. I'll be paying a premium buying it locally, but hey, I need it now. Support local business right?

 

The 570 proves to be a stable fluid with a pretty good boiling point. Many of the higher temp fluids tend to offer a shorter working life to achieve the numbers. As a general rule the higher the BP, the lower the working life.

The only thing that seems to be glossed over at times is that one brand is not really 'better' than another- in the sense that we achieve better braking. Wilwood EXP for example won't work better than 570 unless your temperature needs demand a higher boiling point. If you don't boil what you use now; you don't need a higher bp fluid.

I support the local shop idea but if anyone needs some off the 'net' I have it stocked all the time for a reasonable price.

Thanks for the info. I suspected that most of the stuff out there is just fine. I have heard bad things about Prestone however, and tend to avoid it. I have no proof that it is really any worse than anything else though.

 

I would recommend the Motul RBF600 fluid over all the others, but if this is strickly a daily driver you can actually pick up the valvoline synthetic really cheap and it works great.
I would def stay away from the ATE fluid, been down those problems too many times.

 

Don't forget that when you compress the pistons to install the new pads your fluid level will go back up. I've topped off before swapping pads before and that just makes a mess of stuff that can strip paint.
