DIY: How to bleed STI Brembo brakes - Page 2

stituner420 · 12-20-2005, 06:49 PM

Ah, gotcha! Thanks again. FWIW, I had a subie tech bleed my brake fluid at 30k miles, and he used 1 small container of fluid for the whole bleed. I though it was strange at the time but he said that's all that needed to be done. I'm going to do a full flush when I put in the Goodridge SS lines. Motul RBF600

I changed mine before I took mine to a HPDE and was glad I did...OEM fluid was black. I cringe when I look at the average persons car and think about depleted the fluid is.

I think it's the one thing that will certainly help a car slow quickly next to a good set of sticky tires.

Thanks for the info. I'm planning on doing this soon. Probably going to use ATE Blue though.

They also make a brake bleeder that pressurizes your master cylinder and forces the fluid from there so you don't have to worry about it going dry. I plan on using one of those when I change out my lines here in a month or so. I have the mighty vac vacuum bleeder and it has worked well for me on other cars but I think pushing the fluid vice pulling through will be much easier. You can find them on ebay or amazon, there were some instructions from a bimmer board floating around on how to build one for $25 with parts from ace hardware.

I agree. Pushing the fluid yields much better results than pulling it out, as the fluid comes out a lot more consistently. When you're sucking it out, it doesn't come out nicely.

One more noob question: Is this used to get all the old fluid out also (ie. feed and bleed) or do you drain and then fill with this method.

The pumping action will suck the old fluid out.

What you might wanna do before you start bleeding the fluid out, is, pump out all the fluid from the reservoir and fill with your new fluid of choice up to the brim. Then commence the bleeding, that way, you won't be sucking in the old fluid in the reservoir through the lines, for the time you do the first corner.

Flush a couple times on the right front corner, so that you get fresh fluid for the remaining three corners.

People might say its overkill and a waste of fluid, but better have it throughly flushed.

You have to keep on refilling the reservoir when you're doing the bleeding process like I said.

Great write-up Rev. I also plan on doing this in the next month, and this will be very helpful. Thanks again.

My wife's LGT just hit 30K

I've gotta flush the brakes on it.

It seems these brakes are similar to my old '04 WRX's in comparison to the Brembos. Should I follow the same routine on it? Are there still two nipples per caliper?

thanks for the info

stituner420 · 12-22-2005, 07:58 PM

Well I just have to say that this is a great write-up, but the MityVac pump is the weak link in the chain. I got one from Pep Boys and it took me an hour to bleed one container of fluid out of my brakes. There's got to be a better way. Does anyone have a link towards the pump that pushes the fluid out?

damianblalack · 12-22-2005, 08:12 PM

Check these out for the pressure type bleeders

You found the weakness... It took me quite some time to get it done, but at least once you know the trick and the proper speed to get the bleeder open, wouldn't mind doing it ...

stituner420 · 12-22-2005, 08:37 PM

Sorry Rev, not trying to blow up your spot, but I don't have that much patience or time. My wrist hurts already! How long did it take for you to complete the whole job? How much fluid should it take to flush the whole system (like with a SS Brakeline change)? This other pump seems like it might have something....

Rev · 12-22-2005, 08:42 PM

Seriously it took me quite some time ... like 20 minutes per corner. At first I got air in because I was opening the bleeder too fast.

But I guess you can open the bleeder more to purge the old fluid out faster first, at the expense of getting some air bubbles in, and then you re-do all corners, but air bleeding with the outer nipple. That way you can do it, in, I would say, 1 hour all corners, flushed and bled.

When air bleeding, you don't need to flush a whole container...
