How to Flush your Brake System?

So I think I may flush my brakes tomorrow and replace the pads. I just notice the fluid was getting low.

So #1 I need to flush the entire system if I plan on changing the fluid...correct?

#2 How much fluid do I need if I am going to flush the entire system?

#3 Does anybody have a vacuum bleeder I could borrow?

#4 I think it was asked but can anybody suggest any other good fluids that I can pick up locally besides ATE Super Blue and Motul. I know Summit has Wilwood stuff...

I am sure that subaru might be different but, I read that you need 3qts. For a flush.

Ford stuff is pretty good, cheap and available at the dealership.

I think C&C has ATE, and somebody might have a a bottle or two left from the last "group buy" including me. I'll check in the AM.

Stock WRX brakes, A liter of ATE is more than enough, Motul bottles are smaller but one might be enough for a WRX.

Will a liter be enough with the the bigger 4 pots on the 06?

1 Liter is more than enough, but a pint (~1/2 Liter) isn't quite enough on my car. A liter should be perfect. They sell the ATE for cheap at Tirerack if C&C is out. Make sure you get the correct order. It's not furthest to closest on my car.

It's pretty quick and easy to remove the lower caliper bolt to flip up the pads and see exactly how much life they have left. There are probably peek holes too, but once they get past half way, it's good to take a closer look for uneven wear, etc.

Be very careful not to suck air into the system from the resevoir when you bleed them.

Yeah, I think it's about time I change the pads. It still has the factory pads on it and at 42k I think its time to replace them. They bite ok but not as great as they used to. Plus I have a set of EBC yellows in my garage so why not just do it?

I will try to find ATE Superblue somewhere around Reno today, but if I don't they I wont be doing it today. And I am a little hesitant to replace pads and fluid before an AutoX Thanks for the tips.

Dammit I'm dumb! So I was over at Robbies, and we have my front caliper off and are about to put in new brake pads and guess what....WRONG PADS! I have ones for and 03-05 WRX. So if anybody wants an new in box set of front and rear EBC Yellowstuff brake pads, all they will cost you is a set of 06 WRX Yellowstuff Pads Oh, and Summit didn't have jack for brake fluid so I will probably just order some ATE. Seriously though if anybody is down for that deal on pads it would be great!

[cody]

Bring them tomorrow and I'll be able to tell you if they would fit my car. I might buy them if you make me a deal I can't refuse.

I've got ATE fluid if you need it. I think they cost me like $12 per liter but if you are ordering pads, just grab some fluid too maybe. I'm not in a hurry to run out of it.

Any flex in the caliper is wasted energy.

All of the above is true; however keep in mind this is also just a Vue with street driven miles. In my experience it's unusual to see a large amount of taper or uneven wear side to side on a normally driven street car, unless something is not functioning right. Start with the basics and make sure the caliper sliders & pad guides are completely clean, free of obstruction & well greased, and that the caliper pistons are sliding properly in their bores. A few localized air bubbles in one caliper could also be a culprit, but that should be eliminated with a good fluid bleed.
