Camry hybrid regenerative brake system

Dear friends...

I didn't have braking problems with my Camry hybrid earlier on but after more than a year of ownership I'm starting to have a weird feeling about the brakes. It does not feel as sensitive as it used to be. Now, I feel that I have to press harder to get a complete stop. I don't know whether it's just my feeling or it's the real thing.I believe this could be one of the issues that I could bring up with UMW Toyota.

In one instance, when I was driving quite fast I had to slammed the brake but it did stop brilliantly but there's some juddering feel. I believe its still safe but there's some weird feeling about the regenerative braking system and the software set up.
