xr70 brake help

i have and xr70 that i ride when ever im not on my kx125 and i practice all my wheelies and thing son that but i bent my foot pegs(jumpin it a little too much lolz) and i loosened my brakes and now they are not as smooth they are looser but they are either no brakig or skidding is there a home-made way that i can mod them, i saw a tip a while back about this but i cant seem to find them lolz

p.s. i am gettin the new foot pegs but this trick should come in handy anyway
