hello!
my name is klemen and i am from slovenia, so sorry for bad english :)

i have fx35 and i have replace caliper, but now i cannot bleed breaks. the padal is all the time on the bottom, and do not wnat's to come up. how can i bleed all the air out of the sistem, because i think that the air is problem. i have replace calipers oslo on my renault megane, in it wasnt hard to bleed the system, but on this car i just do not succeed to do that. Is the air in the system problem so the pedal don't want to come up?
how to fix the problem? is there a guide for bleeding the system, are there any trics that i should now?

please help! :)
 
Wow, this post must have gone to the way side some how. I personally word not let this slip by. Anyhow, I assume that new fluid was used and the caliper(s) is good. Just make sure the caliper(s) that was replaced is the correct one; meaning the left is on the left and the right is for the right. If the wrong side is installed, the bleeder screw will be at the bottom side and as air always wanted to go upward, you will never get all the air out of the line. On all the cars that I have work with, the caliper cannot be cross mounted. The brake hose would not be long enough to be bolted back on if the wrong if the caliper was used, but somehow I was able to cross mounted the calipers. Stupidest and a costly mistake ever in my years of DIY on cars.
 
FX brakes don't bleed differently than any other car I've worked on. Bleeder screw is roughly in the same spot and the order should be the same. Furthest caliper first, then work your way to closest one.

The guys had good points to consider as well.

You said the pedal is currently all the way down and won't come back up (i assume no matter how many times you pull it up I press it back again?) which is not normal if it is the case, air in the system makes the pedal soft but still has a bit of spring reaction against the foot.

If my description above is accurate, then either the system is either leaking (one of the bleeders is still open or leaking for example) or you run completely out of oil, or both. It is critical to watch for the oil level the entire process of changing the brake pads, most of such issues are caused by losing oil.

I have never run into a situation where the brake pedal stays depressed. While the brakes will need to be bled, I'd look for something other than air in the lines as the problem affecting the pedal height.
