Hi Help,
Been struggling to set up my rear DM ee brakes. The front brakes sets up fine.
After adjusting the correct length for the brake cable housing, adjusting the centering pin and the cable tension, I am faced with the problem of the pads not "opening up completely" when I release the brakes.
I am wondering if it has to do with the coil spring being too weak (brakes are not brand new). I have cleaned and oiled the necessary moving parts so that they are all moving smoothly.

Or is there a difference between the front and rear brakes and I may have fitted it the wrong way round. From what I can see, the front & rear brakes look identical.

I notice that the length of the housing is important. If it is too long, it tends to push down on lever and prevents the pads from opening back up completely. So I hv adjusted them so there is minimum pressure coming from the housing. This was what I was taught by Ted of Ciamilo as I also hv a pair of his earlier model of Ciamilo brakes.

Should I replace the coil spring or somehow increase its pulling force so as to "open the pads" every time the brakes are released?

Anyone gone thru similar issues with EE brakes?

I'm guessing you've seen the setup instructions but on the chance you haven't here's a link. AEE0204_eeBrakes_G4_DM_2021_11_01.pdf (canecreek.com)
I noticed instruction #2 points out that a cable housing that is too SHORT will also cause the non-opening problem you're having.

Yes, I have read the installation manual. I have cut shorter and longer housing to try out without success. In fact use Shimano housing that is more flexible & not too rigid so it doesn't push down on the cable adjustment screw and prevent the pads from opening back.

I will try swapping the front brakes (that works quite well) to the rear to see if there is a difference between the front & rear brakes. Maybe they are slightly different.

​​rear.The front brakes usually works better as the cable housing doesn't force down on the cable adjustment screw...so the pads open full when it is the release model.

I haven't used the direct mount versions I have two sets of the standard mount versions best rim brakes ever. I would try swapping the brakes I am pretty sure they are directional. I don't know it should really make a difference but they do sell them as front and rear specific. You might reach out to Cane Creek as well and pose the issue. They have excellent customer service.

I think u may be right. I notice that single ones are sold as front or rear. I suspect there are very minor but perhaps important functional differences. Thanks
