Check brake system

[M_Sandro]

Good day everybody, have problem on my Ford C-Max 2012 year production. Appeared error message on dashboards "Check Brake System", local diagnostics shows "Brake Pedal Angle Sensor"  error code, I've changed it with new one but problem still exists. I also changed vacuum booster with recomendation of service guy, but problem still exist. To explain how brake pedal works, its slowing the vehicle when you are driving with high speed (30-40 mph), but when down to 5-10 mph, brake pedal weakens and didnt brake at all if you even push it fully, you really need to make extra powerful floor brake to slowly stop the car. Vehicle hybrid system works perfectly JFYI. Please share experiance if anybody had problem close to it and what could be solution. Thanks in advance

I'm having issues with mine too. Picked up some dielectric grease and was thinking it might be time to disassemble the brakes and grease em up while looking for any parts needing replacement. Though I doubt it as I'm at just under 42k miles on my 2013. Not sure if it's the same exact code yours, but from my live parameters, my brake pedal position (%) never reaches 0%. I'll let you know what I find out. Busy busy next few days for me before my c-min can go back to being c-max haha. After suspension started to fail at maybe around 37k miles or so and noticing that not one mechanic nor technician has shown me they have even a mild understanding of the car. Long story short here I am being out of work for over a month doing all my wrenching and repairs myself as I have more confidence in myself than a shop. Coilovers and adjustable upper control arms are in the works for me along with the brakes somewhere in there. I'll let you know my findings. With my mileage though, I highly doubt it's a faulty sensor.
