My 2012 Mitsubishi Lancer with an auto transmission and equipped with ABS, shudders/vibrates when I put in drive or reverse or pump it at low speeds (i.e. when backing into a space) It performs well at speed, only vibrates when at low speed or when the car is creeping in gear. I don't know if it's the ABS system or if the calipers need to be retightened since the pads and the dics are all still in good shape when checked.
Well I don't really understand what you are saying. You say breaks vibrate when and drive. Now if you put the car and drive and you're stopped I don't understand how they could shut her. But if that's the case it would have to be a problem. And your ABS system opening and closing valves. For some weird reason. You need a pro to scan it when it did that with this ABS scan tool
Rotors could be warped and you could have a stuck caliper.
