Unpleasant Sound

[JG]

I recently Changed my brake pads for all wheels and I was expecting the screech when I brake to go away but it hasn't. Is there something I missed? This was the first time I changed my brakes on my own. All I did was replace the pads

[wparsons]

What kind of screech is it? What pads did you put on? Did you clean or replace the rotors?

[CSG Mike]

What kind of pads are you using?

[Panman]

A couple of more minor things -
were there metal plates on the back of your original pads?
On your new ones?
If there weren't metal plates on the new pads, did you move the metal plates from the old to the new?
If you did, did you apply anti-squeal (or a light layer of grease) the back (non-friction) surface of the pads?
If you didn't move the metal plates and they weren't there already, then you should fit them, applying a light layer of grease to the back (non-friction surface) of the pads.

Metal Plates? I think so. It was all one piece. I didn't add any oil or anything? Didn't think that was needed. Should i lube the rotor?

Ceramic Duralast i got from AutoZone

It's coming from the rear tires and it happens when i initially hit the brakes.

The screeching noise must be due to the absence of lubricant on the brake pad. Most performance pads comes with lubricant, but you can pick some up from your local auto part shop. They're typically labeled as brake caliper grease or "brake quiet". Just apply a layer of it on the BACK of brake pad (sorry for the misunderstanding...). Kind of sucks since you already went through the trouble of putting in all together already... Good luck!

First of all - never ever apply any lubricant to the friction surfaces - Disks or the face of the pads.


Noise from the rear pads is more unusual than the fronts in this situation, but it seems like you may not have done a pad swap before - I'd get a shop to check it if you are at all unsure.

Pad slapping is generally a bad idea... I'm assuming you replaced them because they were worn out? If not, those pads aren't a "high performance" pad.

I'd recommend you take it to a shop; brakes are a core safety component.

So i applied the lubricant Autozone sold to me on the back of the brake pads and the screeching is still there. Not only that. Yesterday I heard the noise when i wasn't hitting the brakes. It was even louder while rolling down a hill without hitting the brakes. Now I'm wondering if it is the brakes. It's coming from the rear though.

I changed them because they were worn out. How will i know if they are pad slipping?

It's a simple install. I only swapped the pads. I don't understand where i messed up.

I guess it could be a wheel bearing, or have something to do with the E-brake shoes.

You can check if it's a wheel bearing, by jacking up the car and trying to move the wheel/tire in a "camber in/out" motion. It shouldn't move, but if the wheel bearing is bad, it will move. Here is more information on how to check.

I haven't had to do anything to the e-brake drum system before, but I'm sure you can find out what to investigate by looking through the service manual.

If you don't feel comfortable, or don't have the right tools. Take it somewhere to have them look at it.

Put your old pads back on and see if the noise is still there. Process of elimination to diagnose the noise.

Report back after you try it.

Do our cars have dust shields? (Haven't been down there yet on my FRS) If so, its possible that there is rock or something stuck between the shield and the rotor. Or the shield itself is bent and hitting the rotor.

DO NOT LUBE THE ROTOR!!!!!!!!!!!!!

I suggest you tow your car to a mechanic and get the brakes properly serviced. (if you are seriously asking that question, I highly suggest you do not put your car on the road until a mechanic looks at your brakes, peoples lives could be at risk)
