Brake booster(?) and intercooler problem

Hello everyone.
I have 2 problems with my Rover 75 Saloon 2.0 CDTI 204D2 engine, 2003 year.

First problem:
I'm driving in a gear with 2000 RPM and when it comes to a stop, I get the car out of gear and when the RPM are still droping, if I press the brake pedal the car wil not stay at idle RPM, it will stay at 400-500 RPM until a complete stop, when the RPM goes back to normal. If I depress the pedal when the car is at 500 RPM but still in motion, the RPM goes back to normal as well, even if I'm not stopped yet. I think it's a vacuum leak, but I don't know where to look, which hose can make this happen.

Second problem:
My car makes a strange air noise when it's in load. It comes from the right side of the engine (when you look at the car from the front). At idle the noise it's not present, even if I rev the car. It's more like an air escaping sound, not the "whoooosh" sound from the turbo. The turbo it's verified and doesn't have a problem. It can be the intercooler hose O rings? I don't think the intercooler itself may leak, because the sound it's not a sharp one, it's more like an air fan noise, but with less air and only when it's on load.

Thanks in advance for help!
