New to the forum, just throwing out some thoughts to the Ford Edge brake problems. I have a 2012 Edge Limited bought new in 2012. Sometime in 2015, the brake booster went out and was covered by the dealer due to the booster recall. When I picked up the vehicle after the repair and drove away, the brake pedal was spongy and went to the floor. I turned around and went back and was told by their service guy it was normal. It wasn't normal and obviously had air in the system. Spoke to the manager and issue got resolved. Today I experienced the same spongy pedal that went to the floor, no brake light or abs light came on, no leaks. My first thought was master cylinder, and it still may be so I ordered a new one today. Checked and found no codes present or pending. In the mean time, I decided to bleed out the system to see what would happen. Bleeding out the system brought back a firm pedal with good breaking but will it last? I have read on many forums where the 2011, 12 and maybe other years as well where experiencing the same issues with the brake pedal going to the floor and mechanics where unable to reproduce the issue and where chasing parts to figure out what the problem was at great expense to owners. I do my own work but still do not like chasing parts to figure out what a problem is. If anyone is interested, I will update on whether the bleeding solved the problem but I will still install the new master cylinder as a precaution.
