I changed my brakes on my F150 4x4 2004 today because had a vibration when stopping anyway. I got everything put back together and took a spin in it and its grinding in the front now .. I looked at my rotors through the wheels and looks like it grinding on the very edge of the rotor. Did I put the pads in backwards ? First time doing brakes help?

 

Not sure what you mean, what does it look like the rotor is rubbing on?

Pads backwards? you didnt put the steel plate thats bonded to the pad against the rotor, did you?

 

Yikes, metal against the rotor? I'd hope he'd have noticed that!

Did you verify that the caliper is "floating" on the pins? Remove the tire and verify the rotor is not siezed. Remove the upper and lower bolt/pins that hold the rotor assembly to its mount, and use some high temp lube and re-insert. Sounds like the caliper is binding rather than sliding along its pins as it should.

 

I will have to tear it down tomorrow and look but 99.9% sure they are not installed with the metal backing plate against the rotor. When hit the brakes its grinding on the outer edge of the rotor. You can see where its grinding right on the edge, No other marks on the rotor.

 

Also check to make sure you didn't bend the brake dust shield. I've done that a few times without knowing when working on the brakes/suspension. Makes a grinding noise when you drive it.

 

Is it grinding on both sides?

 

Yes its grinding on both sides same spot outer edge of rotor is being ground off

 

Have to ask...you bought the right rotors right?

 

Good question.....went and looked at all part boxes and verified them with what it calls for on Oreliys website everything is right

 

On my 06, the pads are shaped in a way that makes it possible to install the metal back toward the disc. I was amazed and disappointed also, that the pads did not come with that wear indicator. I purchased the premium cermaic pads too. If I had purchased the cheap pads, I would not have been so surprised.

If you got a set of pads like mine, I'm willing to bet you installed at least one of the pads backwards (metal to metal). I hope not because it's expensive to replace a rotor. I have never seen a new, correctly sized pad reach the edge of the rotor as you describe. Only the metal backing is large enough to reach that far. You cannot see down inside the caliper far enough to confirm it is scraping down there too, but I'll bet it is. There's no other explanation for the scraping sound. Even if the parts store sold you an oversized pad that reached that high ridge along the edge of the rotor, brake pads would not make that scraping sound. A groove would wear very, very quicky into the pads that matched the high ridge, and you'd probably not be aware of it.

I hope I am wrong. Good luck.
