Trying to even out braking with new tires and lift

[Funky_ChPimp]

Hey everyone, I recently lifted my pathy and put some heavier tires on it and am finding that either I'm not really used to my brakes yet or they're not cutting it. I'd like to get more actual stopping power out of it. Would I have to go as far as changing the whole rotor and caliper set or can I get a difference in stickiness pad? I know my way around a car, but brakes are usually just something I look past. I'd like to spend under $200 if that sets any guidelines and that may put upgrading rotors out of the question. Any insight is appreciated!
