Alright just wondering, never had any other car do this. My s80 T6 in the morning after it has rested/slept all night and I get into it the brake is pressured all the way to where it is not able to be pushed down at all. Now as soon as I start the car it is completely fine and works normal, it is only when I first touch it in the morning and the car is OFF, but like I said it is normal as soon as the key is turned... is this normal?

Thanks ahead of time,
Mike

 

anyone know??

 

There is no vacuum in the brake booster to give you a "soft pedal" AKA power brakes. Once you turn the car on, the electric vacuum pump and/or the vacuum of the engine allows the pedal to become soft and sink down a little bit. Normal operation.
