s60: strange brake pedal air noises

My '01 s60's brake pedal is behaving strangely. The car is new to me so I'm not sure if this is normal.

At first it emitted a high-pitched whistle, an ethereal sound that was hard to trace back to its source. That seems to have stopped, but now it often gives off the hissing sound of air escaping, as if it's depressurizing. Both these sounds happen after my foot is taken off the pedal, and last a good 20 seconds. Mild pressure on the pedal stops the noise.

Your brake booster is bad. This is a known issue on the 01 S60s (perhaps other models as well). I had mine replaced around 90k miles. I don't recall what the price was for the new unit - couple hundred bucks i think.

charlie, thanks for your reply. I just found it on Google - it hadn't come through my usenet server. I also suspect it's the brake booster.

I am having the exact same problem right now. I can't offer a solution yet, but it must be somewhat common if we both have the exact same issue. I've found that if i barely tap the brake it stops until the next time i brake. I would wonder if it was a punctured booster diaphragm, but it sounds like it's coming from the floor.. (I have a '99 S80, i just got it last week!)

The brake power booster is @ fault this needs to be addressed as soon as possible Glenn

My server is missing a lot of messages, including Hank's. I asked the dealer whether there was a recall for the booster, since so many are failing, and he said no. This is not a cheap repair. The parts and labor will run roughly $700. Volvo's got an obvious defect, and they ought to do the repair gratis. But my high mileage puts me out of warrantee.

No there is no recall or service action for this fault I haven't heard of any possible recall in the near future if you are in the US you can contact Volvo customer service & explain your case they will in turn contact your servicing dealer & discuss with them your complaint some times you may get some assistance from the dealer in way of the dealer covering the part & you the customer paying the labor but it rests with the service manger to make the final decision in your case
