Does someone here have access to TSBs? I was browsing them yesterday and found one of interest, it is regarding the annoying squeal that the front brakes make when applied lightly to moderately. I know I've heard some people complain about a brake squealing that they can't seem to get rid of and my brakes are doing the same. Maybe this TSB has the info why and how to fix it. Is anyone able to look this up?
TSB #990523006
If no one can, then I may cough up the $30 to see what it is, depending on whether this brake squeal stop stuff I got at the store works or not (need a new socket first, I broke my cheapo socket trying to get the caliper off
)

Do you have semi-metalic brake pads? I have the Hawk HPS pads and the brembo blank rotors and i get a lot of squeal in the light to moderate pressure range. Once i heat up the brakes though it goes away. A little noise may be annoying, but it isn't affecting the brakig power unless your pads are metal to metal.

They are ceramics. They weren't near this noisy when I first got them but recently they have been driving me nuts.
I have some brake quiet stuff, once I get a new, real socket set (broke my piece of crap made in china socket
) I'll pull the calipers, clean stuff up, and apply that.
