I have a 2011 F150 ecoboost 4x4 with brake
problems, 50K miles and out of warranty:
1) Pedal has vacuum assist and if I don't brake hard, it will stop decent.
2) In a more aggressive stop, like slowing from highway speeds, the brakes feel very weak and don't slow me that quickly.
3) in a panic stop when i hit the brakes hard, the pedal is rock hard and the truck does not stop well at all. The ABS will not engage unless I am on a gravel road braking with my full weight on the pedal.Ford replaced the electric vacuum pump. It did not fix the problem and my ford dealer would not acknowledge that the truck was not stopping properly. I have narrowly avoided an accident three time. Help.
JA: Have you tried "bleeding the brakes" to get any air out of the line?
Customer: Yes, no spongy feel in brakes at all.
JA: What is the model of your '11 Ford?
Customer: F150 ecoboost 4x4.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Just ordered new front pads and was going to turn the rotors. However, after reading several posts it appears that many people are having this problem.
JA: Anything else you think the mechanic should know?
Customer: I inspected all four brakes/pads/rotors. I would say that the master cylinder is not generating full pressure, or the pressure is being bled off somehow. Since this is a serious safety issue and many dealers have sent in info to Ford, I would think their engineers would know something.
