Hey I was just wondering how much fluid you guys/gals have put in when doing a system flush? I did a gravity bleed/brake bleed the other day and didn't even use 1L of the ATE Superblue brake fluid. I remember seeing somewhere to get 2 L but mine definitely wont even take an entire 1L. Thoughts? Comments?

Thanks for the input.
 
if the brakes feel good, the level looks good, and you flushed it enough to where the fluid went from dirty to clear you should be fine

Alright thanks. I was just worried that I did something wrong. Brakes feel a little mushy but i used the 2 person method where 1 person holds the brake pedal and the other releases the pressure on the bleeder valve and tightens quickly without a tube so that may be why. Next time I will go buy some aquarium tubing and put it in a bottle to ensure no air goes back in.

better be carefull how you do that, brake fluid is to paint what cookie monster is to cookies. i would try not to get it all over the place next time

im not sure if a pressure bleeder would work for the system on the ms3 but that could be something to look into. vacuum bleeding also works well. and both are much easier than the old method.

if your brakes do feel a bit mushier than it did before you might actually have some air in the lines. i might try to bleed them again, but do it with the tube next time.

Yeah I was as careful as possible. Backs were fine and only went into drip pans, but fronts kind of shot on plastic. I made sure to clean everything up with CNC brake cleaning fluid afterwards. I didnt notice any visible damage.

Motive makes a pressure bleeder for our car... http://www.jscspeed.com/universal/products/motive.htm .

The brakes dont really feel more mushy, I think it just may be the difference between the stock pads and Hawk HPS pads (which have been said to have less initial bite).

The only thing I notice that is different is that when I pump the brake with the car on while stopped, it tends to push to the floor fairly easily. It doesn't provide as much resistance as before I bled the brakes. It stops fine though when driving. Any idea what that may be?
 
all i'd say is don't pump the brakes with the engine running...why would you want to anyway?

I did it to see if it felt like before bleeding. It definitely does not though. It feels like the pressure drops off. Just want to make sure it isnt a big deal.
