Anyone ever have a problem with an air pressure sound coming from the brake pedal? It just started on my 2001 V70 T5 a few days ago. I haven't noticed anything wrong with the brakes, but the sound is really annoying. It stops when I initially press down on the brake pedal, but starts back up if I keep the brake pedal pressed down or when I let go.

That is the first sign of the break booster bad.There is a small hole in the diaphram and the vaccum is leaking in from inside the car.

Is this a bad thing....I spoke with the local Volvo mechanic on the phone and he asked me several questions about the noise and concluded with, "as long as your brakes are working here should be no problem." Is replacing a brake booster expensive? What happens if I do not get it replaced?

If it goes out totally the brakes will get real hard like it you try hitting them with the car off.

Thanks for the reply....and DIY methods for fixing this or should I have Volvo replace the part?

If you are patient you can replace it your self.If not then you should have a shop replace it.

Just wanted to relpy with the final results....I ended up getting the brake booster replaced. I live in Japan and we have a mandantory vehicle inspection system called "JCI" (I think it's Japan Car Inspection or Insurance). My time was up for the JCI, so I had the Volvo dealer provide a full tune up, and had the brake booster replaced. It ended up costing me about $600 more than the typical JCI, but that included the new brake booster+installation, and they replaced my tourque rod/arm bush and changed out my brake fluids, cleaned my throttle body, etc. My 2001 V70 T5 drives better than it ever has before! Not sure what else these guys at the Volvo dealer did, but I feel like I'm driving a new car.

To be honest, when I first bought this volvo, I had nothing but small malfunctions and troubles, and was having alot of doubts about this car. Now, after driving a temp loaner car (Toyota) for several days during my JCI, plus the great service the Volvo mechanics did on my car, I can honestly say that it was well worth it.

Tech...thanks for all the advice...I'm sure I'll be needing more in the future.

Is the brake booster something that can be done anywhere? My V70 is in the shop now, for a re-build of the moonroof ($1200) and they want an additional $1100 for the brake booster.
