I'm bleeding the brakes for the first time. Two things have me by surprise:

1) The fluid is light green/blue like mouthwash. Is this the superblue fluid I hear about? Must I get more superblue to replace it? Since I am only doing street driving I bought the regular stuff.

2) Using a vacuum pump I'm getting 90% air (leaking at the bleeder) and the fluid is very slow to come out. So out of curiousity, I pumped the brake and got a good, bubble-free flow. Are these speedbleeders, and how can I tell? The one I'm looking at here resembles the one on speedbleeder.com, but has some minor differences (color, tip, etc).

 

bump.

 

those don't look like speedbleeders to me....they look stock

you may get "bubble free" fluid when depressing the brake pedal, but when you let off you suck a bunch of air into the system....not good

 

When you bleed the system, try running a hose (4mm I think) from the bleeder into a cup or bottle of brake fluid, then pump the brakes. This will give the fluid some place to go but will not allow air back into the system when you take your foot off. It may take several pushes to get all the air out so watch the res. fluid tank and keep it full. Also, start with the brake farthest from the res. tank (pass. rear, then driver rear, then pass front, and then driver front). This is how I do it and I get a nice hard feel on the pedel all the time.

 

Yes, ATE Superblue brake fluid is blue in color. When the fluid is mixed with clear brake fluid it becomes bluish/green. As far as I know, Superblue is compatible with regular brake fluid.

 

I think I'll try this method next. I tried again using just the vacuum pump and a better fitting on the bleeder screw, but still got mostly air. A wrap of teflon tape helped a lot for about 3 seconds, but then with a little 'pop' the tape leaked - almost got sucked back into the system. Not trying that again.

So I went and bought 2L of Castrol Synpower fluid, and ordered some speedbleeders. For today I'll employ my gf to push the brake pedal for me. (She just got home).

Thanks worfvi - that's exactly how it looks - dirty windex. I'll buy some Superblue later and bleed that through before I ever take it to a track.

That should read Valvoline Synpower fluid
