Ok So I just turned over 30k miles a while back and I noticed that in the service manual it says to replace brake fluid. I was going to do this when I did the lines and pads/rotors too. Currently I have about 1/4" of pads left in the front. Should I replace all the brake stuff now with fluid change, or wait to do fluid change when the brakes are ready to be done?

I did the fluid and lines first, that way you don't have to open a new bottle later and you can still use your pads for a while if you want (I did the pads too, just not the same day). The pads can easily be changed later by using the speed bleeders, or if you don't mind just by pushing the (more heated) fluid from the calipers back up into the line.

It would probably be about the same amount of time to find and bribe a helper vs. installing the little bleeder check valve thingies, but the helper might be cheaper. The speed bleeders is a personal preference IMO.

I'd do the fluid as required, since brake fluid is hygroscopic. Since your pads seem OK and since you've not complained about bad feel or warble on the pedal etc., if it were me I'd just leave things alone provided everything looks good once you've had a close look. Since the pads are wearing though keep an eye on them as you rotate wheels routinely. You could upgrade pads and/or rotors "while everything is apart" but the question is then time and money. If you like the brakes, I'd do the fluid since it's required and call it a day. (Keep receipts etc. for warranty).

if your going replace lines soon this requires a bleed, I'd wait

if it is not going to be soon, bleed/flush now

soon- a month or less

So you recommend installing "speed bleeders" while I'm there?
They just make it easier to compress the caliper and remove the heated fluid without having to bleed them or suck it out of your reservoir.

how long do you plan on keeping the car for ? i remember you talking about getting the new STi...

have you looked at the pads to see how much life is left on them ? SOA covers your pads for 3 years/ 36k miles... if they fall under 5-10mm i think, they replace them for free
i would flush the fluid now... wait for the time to replace the pads then just do the whole upgrade...

thats a good price for that package btw

the one w/ the rotors thrown is nice, but if your rotors still have lots of life in them- pads/lines/fluid are the biggies

I haven't mic'd them, but the car has 30k miles with 0 track days or events. I'm guessing I'll be able to get at least 1 turn out of them?

Well I bought this kit:

http://cgi.ebay.com/ebaymotors/Subar...5058QQtcZphoto

and one just like it for my wifes Scion as it needs brakes badly.

Lookin at gettin a motive power bleeder too.

http://www.jscspeed.com/universal/products/motive.htm

I found the wear limit on the 06 front rotors is .89" Drug a tape measure across and think I'll be fine. Checked and the front pads are at about 1/4" while the rears are at 1/2".

Ok to have mismatched pads on the Subi? Or do all 4 at once no matter what?

I think you will shift the bias even more forward if you just do the fronts. Have you looked at the H6 option (not sure if that applies to your model year even)?

I'd do both front/rear personally.

I think he has a 06 so already gets the 290mm rear rotor.

Yeah the 06 has the large vented rear rotors. Ok I'll just roll on the rear pads at the same time.

Im a big fan of over doing stuff, i treat my things with the utmost respect, sure it can get a lil expensive, but its better to take care of it now, than have something happen later in the long run, like me, next oil change is due in about 3-4k, and im problably going to get the Red Line power pack(comes with the exact amts of fluids you need, ie oil, gear oil, etc), brake fluid is agroscopic, which means over time it accumulates moisture in it, and moisture in a brake system can lead to a squishy pedal or if left for a long enough amount of time, real bad problems(swelling, hurting seals etc, but thats an EXTREME case, not the norm), i vote for bleedums, you'll problably only need about a quart or quart and a half to do a good full system bleed, and it'll give ya peace of mind....... but thats just me

annnnnd we have porn with the poll!!!! I dunno what it is about the poll feature that attracts spammers.....weird.

Anyways.

I ordered the stoptech stage 1 kit and come to find out they have a back order on the axxis ultimate pads. So instead they discounted the kit and are sending me lines and fluids. I figure I have another 10k miles to go on the fronts anyways and kinda wanted to run Hawk HPS anyways so no worries.
