Uphill acceleration

I have a 2008 Honda CR-V.  This month I
have had to have all 4 breaks and rotars
replaced, two front tires, AC worked on,
and a break master cylinder changed.  
After the master cylinder change I have
noticed the car acceleration more slowly
up hills in particular. Is this and issue from
the master cylinder, or just normal change
from doing all of this break work causing
the car to feel different?  The crv makes it
up hills just fine, it just requires more time
to build up speed.
