Soft Brake Pedal

I just took off my winter wheels and tires and put the original 20" low profile run flats that came with the car and now my brakes feel like they need to be bled! I have to pump them once to get them firm and remove the 1-2" of dead brake pedal travel.

Does anyone have any idea why this is, I can't think of any reason.
Thanks for any advice.

Unless you've damaged a brake pipe, there's no reason for this. Check for leaks.

I haven't damaged a brake line and there is no leak. Its as though the system got some air in it. I checked the reservoir and it is still full.
Weird.

i have the same issue on my w205 c300.... when i don't apply pressure on the brake pedal i feel it sink down...if i apply lots of pressure..i still feel slight sinking...(or it's in the head)

i had a thead about brake booster hissing when releasing brake pedal..but nobody really said that they have a similar issue...

dealer said they looked at brakes and it's fine... i also have the occasional brake squeek that i haven't complained to them about yet....
