RE: Roger did the hacksaw trick work on your break
I just did it last night and will see over the next week if it was a fix. I also took the retaining pins and polished them in the lathe as I have heard they can contribute to the problem. I'm keeping my fingers crossed. I think the pads I have are semi-metallic (they have flecks of metal in them) they are the lifetime pads from Auto Zone.
The next stratagem is to wrap coarse sandpaper around a piece of wood, so the surface of the sandpaper remains flat, and sand the brake pad medium to remove any tiny high spots in the material. You can usually feel the high spots with your thumb.
Saw cuts and/or evening out the medium have always done the trick for me. Man, I hate those sanctimonious looks I get from guys in beat up Chevy Vegas when I pull up to a stop light in my nice ZX with the brakes howling!
