I think we had the same problem when I was doing my brake conversion. Someone (I am not saying who) put the outside pad on the inside and we couldn't get any pedal pressure. I think the OEM pads might be marked L and R.
On the R56 there is a difference between the inboard pads and the outboard ones. The inboard pads have more of a circular shape in the center of the backing plate.
I am not sure exactly what the issue might be, but I would first start by going over the re-assembly. I would suspect that something is not assembled correctly. Maybe you could snap a couple of pictures of the brakes and we might be able to help a little bit more.
Def Chk the assembly again, been there done that and have the emotional scars to show for it. :mad2:
You also don't mention having to compress the brake cylinder, did you fail to mention?, get lucky?(you must have if you got the calipers back on the rotors)
"inside-outside" okay I understand now. Yes the pads are on correctly. I plan to take it all apart again today a triple check the assembly. Yes I did compress the piston back to fit the new pads. Took the cap off of the Master cylinder. I put the cap back on once all was back together. Started the MINI pedal went to the floor as expected. However it will not return to firm. Once again I did NOT open any of the lines or bleed screws. So I am curious as to how air entered the system if that is indeed the case. Thank you all so much for your suggestions and advice.
Yes I have and it does stop! (good thing). In drive and reverse the pressure and pedal feel is better and it does not go all the way to the floor. In park at idle it holds then slowly sinks to the floor. At release it come back up. I pulled it all apart again today to triple check the assembly and all was correct. I also checked for leaks and there are none I could see. I am going to attempt to bleed them tomorrow.
