I have a 2001 V70. The brake pedal pumps up fine and retains pressure with the car not running but while driving the pedal goes down almost all the way to the floor. Replaced rotors and pads all around and no visible brake fluid leaks. Could this be the power booster? Any Advice would be appreciated. Thanks

 

Hello, Check your master cylinder. How long ago did you replace the pads and rotors? Kira
