03 Volvo S40 - Brakes operate as if there is NO power

Customer Question
assist. Hot COld good...
03 Volvo S40 - Brakes operate as if there is NO power assist. Hot COld good weather or bad the car does NOT stop the way it should. It is very much the same as my 82 MB 300 D when the Vacuum pump failed. You have to STAND on the brake pedal in hard braking situations.
JA: Have you checked the spark plugs? When was your air filter last changed?
Customer: Pugs and filters all changed recently. Those things have NOTHING to do with this problem.
JA: What is the model of your '2147481646 Volvo?
Customer: 2003 Volvo S40
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: YES. I have bled the brake system, changed the brake pads - same results. Brakes work but as if they were non power assisted.
JA: Anything else you think the mechanic should know?
Customer: The Volvo S40 is a 1.9 liter turbo w/ 75,000 miles. runs very well.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Volvo Mechanic about your situation and then connect you two.
