Breaks Sound Like Hell After Change

[alero_ecotec]

So, i had my car into the dealer for some break work about 2 months ago, i only had the pads changed at the time, everything was fine after this, About a month ago i had the discs changed, and everything was fine, so i came back to college and my car sat for about 2 weeks, and when i drove home last weekend it now squeels like no other, just a high pitched whine. I dont know, i dont think its that big of a deal to take it back into the dealer for, but its kinda crappy b/c i'll have my car looking nice and neat, and then i'll pull up to a stop sign and it will sound like nails on a chalkboard. Anyone have any idea if i can do anythign to fix this?

Could be a caliper hung up. You could grease all the slides and see if that helps.

i really dont know else to do besides attack them with a can of wd-40 or something

I bet it is where you car sat for that long the rotors got surface rust. Then the brake pads have a piece of rust stuck between them. I would say take it out in a safe place and do some hard braking. like 30 mph then press them pretty hard. Not hard enough to trigger the ABS or lock up the wheels, but right before that point.
