Re: Laguna 2 dci brake pedal hard

I suspect the small black box you refer to is the turbo actuating solenoid but without a picture or better description I can't be certain.
The vacuum pump has two outlets - one for the turbo actuator and a larger one for the brake servo.
You'll need to check the plumbing going to the servo.
Also check in the passenger footwell for signs of hissing as it is known for the air seal to fail thus loosing brake vacuum assistance.
