Replacing brake fluid with hi-temp

I am planning on replacing the DOT3 brake fluid in the STi with some DOT4 hi-temp stuff, anyone know the capacity of the 08 STi braking system?

Also, what order the wheels need to be bled in to ensure that I get all of the older fluid out?

 

Start with the furthest wheel from the master cylinder. If you don't let the master go dry you shouldn't have any problems.

 

not sure if the 08's are the same but on my 04 the left rear is the farthest from the bmc

 

Get plenty, about half a gallon just to be sure. You can always return what you don't need.

 

Half a gallon??!! Seriously? I was thinking 2L!








oh, wait....... 2L = .5Gal..... :biggrin:

 

I can't speak for the sti but the 2.5rs has a funny bleeding proceedure. not the typical start from the furthest wheel. I'd try and look into it more. .02

yea we re-ran all the lines (hardlines and softlines) on my car and didn't use an entire bottle filling the system

 

Yes, .5 gallon was kinda high, I know. But you never know if there will be complications.

 

^Thats what I was alluding to. Does that apply to all subarus?

I <3 super blue, although I've been questioned at two track events about why my fluid is dark.:biggrin:

 

does what apply to all subarus? complications? lol

 

LOL, edited for fast posters

 

you have to remember the brake lines are small, the most fluid you have is in the reservoir itself... so buy a cheap turkey baster, suck it down till there is only a small amount left in it.. top it off with new stuff and bleed... at tops you would need 2 qt size bottles... and that would depend on how many times you bleed from each bleeder...

 

Thanks for the info. That link provided exactly what I was looking for in the bleed order.

I am also replacing the stock for the blue, so I believe that it will be pretty obvious when I get to the new fluid. It's just too bad that I can't put steel braided lines on the car, this would be a perfect opportunity...

 

Does anyone sell ATE or Motul locally?

Also I do not want to deal with so does anyone want make some money that has done this before?

 

Looks like MAP sells both give them a call.

That's where I am getting my ATE from, provided they can get some stock before the weekend.

 

I bought some Motul from them last summer since they were out of Super Blue forever. Good stuff, works amazingly well. Brakes feel a thousand times better, much firmer pedal, no more sponginess. Although, I gotta admit I've never actually used the Super Blue brake fluid.

 

I'll check with them, Adam says he can't get it for the weekend.
