Hello GS'ers

I searched the archives, but couldn't find an answer for the following problem:

When I apply my brakes, the system makes a strange, hydraulic gurling sound, which disappears 1-2 secs after I take my foot off the pedal.
This happens even when the car is at a standstill and in park.

My dealer told me that this was common in GS'es and IS'es, but I'm not sure whether or not he's BSing me.

Any help would be appreciated.

Thanks

Bleed your brakes. If it doesn't go away, and doesn't adversely effect braking, you may just have to live with the noise.

Is it like a "pump" sound? If so, it's normal. I'm told it's a self-check or something like that. Mine does it like every 4th brake use.

The dealer told me it is the computer calibrating.......under quick re-action times(to press the the brake pedal), the braking system will actual apply more braking force without having to press the brake deeper.

Hope that makes sense.

2 try it out, next time it rains, snow, ice, at like 30-40mph, tap the brake, very quickly, u will notice that alot more force is applied without have to completely depress the pedal.(and u will hear the computer making is noises..)
