I just replaced my rotors and pads in the front, now they squeel constantly....

[16g-95gsx]

Ok, I have new powerslot rotors in the front along with hawk RPS pads. The hawk pads are a very nice semi-metallic pad for those of you who have never heard of them. Anyway, the pads themselves came with a metal plate on the back of them, but had slots for the stock shims to fit into. Now even just jacked up if you spin the wheel the pads scrape against the rotor the entire time, is this normal? I put the shims on but I'm almost wondering if I didnt need the shims as they did come with a plate on the back of them about the thickness of the factory shim, so it's almost doubled up it seems now. Although like I said the pad did have cut outs for the shim to snap on. The entire time I drive now it's a constant squeeling, not seriously bad but it's there. DSM guru's please help me out here

It should have really tight clearances between the pad and the rotors. Try using anti-squeal applicant. It comes in a tube and you just smear a light coat on the backside of the pad. This kinda keeps the pads on the pistons and if there is space between the shim and the pad, it will help keep the shim from pushing the pad into the rotor.

Is it normal to have a pad constantly squeel and rub on a rotor when you first replace them both? Even during regular cruise there is a cosntant squeel, and when the car is lifted it rubs on the rotor (the pad). The pads came with metal plates on the back of them, but I put the stock shims on as well. There were grooves for the shims to go on, should I take the shims off though? What were those metal plates? Were they "shims"?

It could be that the pad is just resting on the rotor as it travels?

Did you put on "anti-squeal" compound? It sorta holds the pad to the caliper, so it doesn't flop around, and rest on the rotor when the brakes are off.

Yea I did, it appears from my extensive research here (I spent forever finding a good comment about it) that these pads come "100% shimmed" meaning that metal plate I was talking about apparently is the shim, and that the fact that I have the factory shim on it I guess is just pushing the pad into the rotor too much. That's my guess. Could this hurt anything driving it a small bit like this?

SAME THING IS HAPPENING ON MY CAR.....
DID ALL THE COMPOUNDS, PROPER TORQUE....
ANY PROGRESS?

 

[16g-95gsx]

Heh, if people would post back then MAYBE I'd get some progress . However it appears that my pads may not have needed the shims as the metal plate on the back of them might have been all hte shim I needed. I will hopefully find out 2moro, although I am not totally sure since it will be sunday.

How long have tou had them on? My suggestion would be this, although it sounds shady. If there is no squeel with out the shims leave them out and take it for a test ride. Do a few hard stops, but not so much your master cylinder is boiling and your rotors are smoking. Come back and see if the shoes have worn in enough for the shim to fit.

One thing Not to do is throw those shims out. You may find yourself switching to another brand that does not come with shims and then your @ss out.
