Braking issue

[plourded]

When I was pressing the brake you could feel it jerk like if the rotor were warp, So I put some new rotors and brake, it drove alright for a few hours there it goes again. I brought back the rotor for some new one and it does the same thing. Could the caliper be my problem?? Ever happen to anybody.

Did you replace the pads and the rotor???
Does the jerk only happen when the brakes are applied>?

if you only replaced the rotors then chances are the pads are worn unevenly and probably causing the same reaction.

if you replaced the pads too then i dunno

I replace both rotors and pad, and it only jerk when I apply the brake. I'll probably bring the car to gm to get it fix cause it's getting anoying.

Does it do it all the time or just when you start driving it after it has been sitting over night?

It does it all the time, I notice it more when there's more people in the car. You can feel it on the brake pedal.
