Brake Noises

Alright...I have a 2002 Eclipse RS 5 spd. Yesterday, I got 4 new tires, rotors resurfaced, new brake pads, and an oil change. I got my rotors resurfaced b/c they were warped and would cause my steering wheel to shake when i hit the brakes. Well, here is the deal. My brakes did not make any noises before the brake job, but after, it makes a noise when i stop. It isnt a squeeking noise, it actually sounds like an airplane engine turning off (kind of like a winding down sound...It goes from high pitch to low pitch as i slow to a stop, then quits when im stopped completely.) It only happens when the brakes are pressed. Maybe, this is just the new pads wearing in or what. Does anyone know what this may be? or is this normal.? Its not a loud whining noise, just a winding down sound. Any comments would be helpful. I have 33000 miles.

i believe that might just be the pads breaking in

o you have Semi-Metalic or Ceramic Pads?

yeah the compound, and did they tell you to go easy on them for the first 500 or so miles? one more thing- you should have got aftermarket rotors installed.

If the pads have a wear indicator it might be rubbing. Sometimes when they put pads in they accidently force the metal tabs down, so even though the pads are new, the indicator is hitting the rotor. It probably is just the pads wearing in, And im betting the noise goes away after a couple stops. If the noise is still there after your breaks are warm, then I doubt its the pads. If it keeps doing it I would take it back in, or take the calipers apart and check for debree.

When pads are changed, they need to be bed in properly...any noise from the brakes is due to something vibrating...this could be quite a few small things

Perhaps they didn't put enough lubricant on the shims or the piston
Perhaps one of the caliper bolts wasn't tightened enough
Perhaps your pads weren't bed in properly and they are set a bit off or uneven causing vibrations when applied to the rotor.

As you got them all done for you, I'm assuming you aren't entirely comfortable checking/doing them yourself (sorry if my assumption is incorrect). So I would suggest just taking it back to the place you got them done and ask if they could just check it out for you really quick. If they are competant, it should only take a few minutes, as long as you can identify which wheel it is coming from beforehand.
Hope that helps.
