whr1966 Posted June 22, 2018 Report Share Posted June 22, 2018 I have a 2011 Edge. Today my brake pedal went to the floor. It stopped the car but scared the bajesus out of me. It's done this before and returned back to normal so I thought it was a fluke. Any ideas what this could be? Car has roughly 160K. Booster? Master Cylinder? ABS?

WWWPerfA_ZN0W Posted June 22, 2018 Report Share Posted June 22, 2018 Odds say booster, especially if the fluid looks good and is not leaking from anywhere. Typically accompanied by a hissing sound, though it may not be as noticeable in early stages. Did you have the brakes serviced recently?

wisdomsp Posted July 31, 2018 Report Share Posted July 31, 2018 I'm dealing with this now too. mine seems very intermittent, but I do notice an all around softer peddle feel. 2013 2WD 3.5. I'm leaning towards the Hydraulic Control Unit and a stuck valve. There are some test you can do to check the booster. mine checked out good so far. Check out this guys vid.

Ntrain2k Posted August 6, 2018 Report Share Posted August 6, 2018 Mine was intermittent as well. New booster fixed it. Quote Link to comment Share on other sites More sharing options...
wisdomsp Posted August 14, 2018 Report Share Posted August 14, 2018 Hmm. I should take mine in and see if they will find a bad booster. I really don't want to through a bunch of parts at this thing... Quote Link to comment Share on other sites More sharing options...
