breaks poping

sometimes when i put on my breaks , they seem to make a poping noise... i put now drums, and shoes on the back and new pads on the front last year... should i just replace the rotors??

My 2001 Ranger Edge does the same thing. When I purchased the truck they said it was the ABS and I agree, BUT the ABS should just pulse your brakes not make a loud poping sound like your rotor is bent like a taco. Does your truck try to pull to the right or the left at random on occasion when you apply your brakes? Mine sure does.
