Okay... so, yesterday at 3pm, I'm driving home from university. I normally have to cross a tunnel.

Upon starting the car, soon as I started, when I would brake to ANY degree (although more noticeable below 20mph), I would hear a kind of chirpy 'whoom whoom whoom whoom whoom' sound combined with the sound -and feel- of stepping on an old wooden creaky board coming from my brake pedal.

In 5 minutes, this got literally ten times worse and I had to stop and have the car towed all the way back because it felt like something was about to snap (hence the board analogy) under my foot.

The chirpy noise sounds like something I've heard before (although I forget where).

The noise that's scaring me is the noise that sounds like a wooden board. Whenever I break, the wooden board creaky sound gets louder and louder, the brakes kind of stutter, the pedal shakes a bit, and it feels like I'm about to snap said wooden board. The stutter and shaking isn't bad enough to where it steers the car into another lane or anything, but it is still noticeable and kind of scary.


Here's the other nerve-wrecking part. It's in the shop. The technician has taken it out and back into the shop twice now. He hears the noise, but he's never heard it and he has no idea where it's coming from. I've got like 2-3 technicians on the car (since ~5pm yesterday to whenever they close, and from 7:30am when they open today until now at 11am) and nobody's got a clue.




Anybody ever heard of this before?

For the record, there are -no- aftermarket things on my car (except for the K&N for about a month), I do not drive it hard, I do not slam on the brakes, I don't race it in manual, it has been in no collision or any other sort of detrimental situation.

Could be so many things. Hard to diagnosis over the internet. My GUESS, from what you describe is a hanging caliper.

Hmmm, is that easy to fix? Sounds like an easy 'put it back on' thing. Although, yesterday I looked and felt all four wheels and brake calipers to see if anything felt loose, but nothing budged even a little. That and the technicians certainly by now have taken the wheels off and would have found it?


I hope, assuming that's an easy thing to fix, that it's that!


I want my 'Bu back! XD

Like SilverLTZ said, that is a litle hard to diagnosis over the internet. However, does the car seem to pull one side or the other? Any other noticable noise coming from outside the car when you get this "Board Creaking" noise?
I would put the car in the air, rotate the tires by hand one at a time, then have someone apply the brake. Listen and watch each wheel to see if you can pinpoint the location of the noise and operation of the caliper.
Please let us know what you find out...

Here's hoping you get your Bu back soon!

There is only about 1% "pull" and it's not a pull as much as a shake (it doesn't pull to just the left or just the right and it doesn't even pull it outside the lane, just makes the car a little shaky). Also, there is no decrease in breaking power (other than my fear of pushing too hard). While I state it makes the car "shaky", that might have been slightly misleading. It's kind of like when you break really hard and the ABS catching (correctly), the car is going to stutter a little and it's not going to be in a perfectly straight line as you brake. This is kind of what it acts like (the stuttering, not the ABS or anything) when I say "shaky"

Also, other than the kind of chirpy noise, there is -no- other sound from the car.


Also, -no sound whatsoever- comes if the car is in park and I apply the breaks. It is -only- when the car is in some sort of motion (even 0.1mph)


Yea, I'm just like... gaaah I want my 'Bu! XD

(and I have off today, so I'm sitting at home bored :/)

Found what was wrong!

The service department stated that apparently when they resurfaced the rotors (about a week ago the 'Bu was in the shop because my rotors somehow warped x.x) apparently the machine that does it left a non-smooth surface (they didn't say if it was a dent, line, scratch, whatever) and that non-smooth surface was what was causing the feeling and noise I was getting.

They said they have fixed it, the technicians have test driven the car multiple times and everything is perfectly fine now!


So, in about an hour I'll have my 'Bu back!!

Sorry about the frantic nature of this topic. I was at home today (no work or class) and bored... without my car!! :'(
