New pads squeal like the old ones

Jukelemon · 07-03-09, 10:46 AM

So, I replaced the pads in my truck. The others were shot. Here is the thing...front still squeals like the pads are shot.

i have not gotten new rotors yet-no extra cash. I did not think a warped rotor would cause squeal.

Ideas?

I used all of the anti squeal shims when I replaced the pads.

Thoughts?

Im thinking rotors are warped or calipers are sticking.See if you can have the rotors turned,manually move the calipers and see if they are sticking. 2 cents MIke

What brand pads are they? The OEM ones have never squeeled for me.

The caliper are not sticking. Rotor moves freely. As a matter of fact, when I took the pads off, I thoroughly cleaned the pad pins and cleaned the rotors.

They are not OEM. Nappa basic.

If the rotors were significantly warped you would feel a pulsation in the peddle.

Did you lube the pads/hardware when installing? Most pad squeaks have nothing to do with pad composition, type or condition, it's the metal to metal contact with extreme pressure.

Get some "brake grease" commonly available at parts stores or can use any silicone waterproof type grease if you have some. Take the pads out and put a slight skin of grease on the places where the metal backing plate of the pad touches the caliper, I also put it on the pins, anti rattle clips, anywhere there is metal to metal contact. You want a slight skin, doesn't take much and only on metal pad and caliper parts, none on the composition part of the pad or rotor, if you get any there clean it off with brake cleaner.

Yeah, I have the pulsation. I know the rotors are bad. No question there.

I did not use any Brake Grease. Just cleaned the pins, shims and calipers.

Maybe I need to go over them again.

Make sure to check the cost of new rotors, they aren't that hard to install yourself. Many times it is cheaper to replace then to turn them. Plus if you elect to turn your rotors you will have to pay an hour labor or more, thats if they have enough left to turn.
