I just installed new rotors, calipers, brake hose, and brake pads on my 95 F150 2wd
. Now when I am driving, I have a continuous scraping sound which I have narrowed down to edges of the rattle clips hitting the wheel weights.
it happens on both sides of the vehicle. I have tried new clips, verified that they are seated fully.
My question is can I hammer these clips down without affecting the breaking? Or have my wheels rebalanced? Did I do something wrong which may have caused this?
Have a quick look and the brake clips, see if they have migrated over and are rubbing on the rotor. I’ve had to tap the end of them over to keep them aligned properly, so they don’t rub on the rotor.
They tend to be very tight. I left a nice groove in my aluminum wheels because I accidentally bent the clip when replacing the wheel bearings so might just need bent down a little farther.

hmm yeah it is definitely scraping on the weights. i was able to replicate it by jacking the front up and spinning the tires.
i think the pad’s ear is a little thinker than the previous pad and it’s causing it to hit the existing weight. Since it’s happening on both sides, with the same wheel weights.
Definitely looks like something has been rubbing on the weights. But it wouldn’t be continuos, it would only make noise as it rotates over the weights.
You should be able to see it easily from the back if it is hitting the weights. Or, when the wheel is off if is still makes a rubbing noise.
Those pad clips are fine
Move the tape-a-weights like Conanski said in post 2
Do not mess with the anti rattle clips, (they are hard riveted to the pads)
If you do anything to them (like smash them down) that pad will just rattle around and squeak
OP - In theory the clips should be lower than the caliper, hard to tell in those pics.
You don't need to 'mash' anything. You are tapping/bending the ends of them to stop them from sliding side to side and riding on the rotor. I've had to do that on some newer clips, the keeper tabs were bent slightly too wide and allow them to migrate sideways. when that happens, they contact the rotor and makes a continuous 'scraping' sound - Ie. They are scraping the rotor.
I'm not aware of any anti rattle clips on these trucks that are riveted to the pads.
Its one more suggestion to look at if you don't find an issue with the weights contacting them, or you have more than one issue.

Reason: Mechanic error
I stand corrected, those clips circled do just clip on the caliper mount
He just needs to move the wheel weights off the inside, or just move it inboard 1 quarter inch if he wahts no weights on the outside
Those clips should be on there straight anyway IMO and should clear a tape -a -weight
Maybe get new clips
Bending them sometimes does work, but is time consuming and not cost effective IMO
Thanks for the responses! Very informative. My initial description of “continuous” was not the right way of describing it. It’s continuous in the sense that the scraping happens even without braking. When I spin the tires when it’s off the ground I can say with certainty they are making contact with the weights.
I had an extra pair of clips that came with the caliper. Different manufacturer, and it still happens on both sides. Which leads me to think that perhaps the ears on the pads are slightly thicker than the previous ones, causing the clip to stick out more.
The weights do not appear to be lifted at all and appear to be in good shape.
I’ll try and bend the clips in so they are below the edge of the caliper and I’ll report back with a picture of it along with a video of me turning the rotor. I still have another pair of clips if it doesn’t work out.
Ok, That's not what I mean at all. They will drag (scrape) on the rotor with brake applied or not.
I do not mean hammer the top of them down into the pads to gain clearance. If it is hitting the weights, ss Conanski first suggested, move the weights.
If the clips are too wide, the shifting will happen side to side, not up and down.
