Squeaky damn brakes!
 

My front brakes are squeaking like crazy!

I have Rototech slotted and drilled rotors along with Wagner pads. All in excellent condition.

The pads' leading edges have been tapered to prevent the lead edge from squeaking but after doing that, the squeak is just as bad. The metal guides at the top and bottom of the pads are in good shape.

Has anyone experienced excessive noise from their brakes? If so, what did you to do fix it?

I've had squeeky brakes from pretty much day 1. Stock Cobra rotors and EBC() GreenStuff brake pads. Haven't fixed it yet.. no money

u could put some silicone on the back of the pad, that usually prevents squealing.

My Hawk pads and Baer rotors are totally quiet.

I've seen it mentioned somewhere that a couple of good blasts in reverse and heavy on the binders can improve/minimize the squeaking.

Pretty easy to try out this theory.

Are you sure your rotors are clean, i.e. no dirt, brake dust, grease, oil, etc.. from the install? I'm usually very generous with the brake cleaner when I change my pads..

you have crankwalk. Sell your car now.

The pads and rotors have been on for almost a year now. I always clean the rotors very well when installing them and if anything was on them, it's long burned off at this point.

did you use any brake quiet on them? its a silicone like substance that you put between the caliper and the brake pad. The pad could be vibrating when the brakes are applied. I've had the same problem in the past and used the brake quiet and it fixed it instantly. High heat silicone works good to!

As suggested above try using high head silicone to bond em to your caliper, another idea is to use the new spray on (applied directly to your rotor surface) brake quiet. Either idea should at least improve things.
I will however add that the slotted / drilled rotors on my pickup truck cause the same issue that drove me nuts until I finally took em off. Same pads on standard premium rotors and no squeel / noises.

are they semi metallic pads?

I think those are normal to squeek a bit
