new brake or pads

i can’t decide wether to get a whole new brake setup or just change the pads to metallic ones or whatever they are.. i have 1900 miles on my xxx and still on same exact brake pads and rotors but i can wheelie really well sitting down. the second i try and get on my knees to do combos it’s impossible even w a seat cover. I feel like this is either because of my brakes, me being 6 foot with stock bars and no riser, or i just need to practice more.. any advice? I can either get a direct mount or brakes i don’t really want to spend more money than i alr have.
