I have an intermittent grinding noise coming from what sounds like both front wheels,it sounds like metal on metal almost like something metal rubbing the rotor but I just put new pads on and the noise was there before as well with nothing touching the rotors but the pads. The sound will appear out of no-where at low speeds of 35 or below and will continue until I brake and slow down, just before I come to a compete stop the noise will stop with a slight clunk. I can then drive away with no noise. I am pretty sure it is not brake related except maybe ABS somehow but was also thinking front axle or diff, also have read posts that are bearing related, but both at the same time?. It is the slight clunk before stopping that I can not figure out is related to. thanks in advance Vic
it is an 05 f150 xlt 5.4 super cab 4wd with 85k miles
Not at all hard to diagnose and repair. ...and way easier and cheaper to fix than the items you mention! You can disconnect (and plug) the vacuum line as related in the thread, until you get the parts. Just don't drive around in 4WD, unless you want some serious expensive repairs.
thanks for the quick and informative response, that is a pretty complete thread and gives me a place to start. Could be that there was a slight leak and my moving around of the calipers not paying particular attention to vacuum lines may have made it worse since I did the new pads.
thanks
