DIY: How to bleed STI Brembo brakes - Page 3

stituner420 · 12-22-2005, 08:44 PM

It was taking me considerably longer, literally one of the mity vac's container's worth of fluid in one hour...oh well. Maybe I wasn't opening it fast enough, but it sure had a lot of bubbles in it!

Good to know that you tried

If you ever get the other pump, man, please post a thread with your experience.

And I do agree it was painful doing it with the MightyVac, but well, none of my friends wanted to help me do it

LOL. mine either! Will do on the review.

I was in the midst of writing a DIY up when I stumbled upon this thread. I suppose Im a week late

When I bled this week, the pedal feeling is there, there is just a small distance of travel where there's nothing and then bite. I took the car out, triggered ABS (thought it may be that or prop. valve), and came back. Checked for air in the outer valves, nothing. Pedal still has that small travel. After triggering the ABS it improved, but isnt where I think it should be. Perhaps 85%, rahter than the 100% I want.

This is with new pads and SS lines btw.

Bump... I updated the first post with some information about different brake fluid boiling points and prices

I'm sure your can find them elsewhere too.

Is the 45mm cap size correct for an STi?

Rev, thanks for the awesome DIY. Was planning to do my brakes for the first time and glad I a saw your post!

Nice Thread I am going to need it when I upgrade my brakes in the spring.

I'm going to try this finally. If it doesn't work with the mity vac, I can always resort to the speedbleeders.

Bad things about the speed bleeders is the tread sealant gets hard and in one or two bleeds you'll start to get air through the treads.

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.

Woah, I just looked at a DIY power bleeder from a BMW site and I would suggest caution. It says to use an of the shelf container, build the contraption and presurize to 10-15 psi of mostly air. Well the container will also have a large amount of brake fluid and depending on the volume of the container, 10-15 PSI is a lot. So if you make it yourself, be aware that if this thing blows, it's not going to make your ears, garage, eyes and car paint happy to say the least.

Well the MityVac does it's job after all, might be a lengthy process but it works ...

2fas4u · 01-30-2006, 07:46 AM

Yeah I have used the mighty vac for a long time now and there is nothing wrong with it!! Although I just bought one of the Motive units so now I have both....

***kwkSTi*** · 01-30-2006, 09:27 AM

I used the Motive pump and installed a set of speed bleeders - a fast and effective combo. My only complaint is the Motive pump took two containers of Motul RB600 to cover the bottom of the pump siphon sufficiently.

I Picked up one of these, but have not had a chance to try it out yet:

They also have one that doesn't need an air compressor and has a huge vacuum tank:

I've used the motive pump (on my 944 Turbo)/w speed bleeders and didn't care for it too much, like the above poster mentioned, you have to put a lot of fluid in it for it to work properly. Kinda wasteful. I have also heard that using pressure to force the fluid through the lines adds air to the fluid. I.e. some of the air in the tank gets forced into suspension in the fluid.
