The rear rotors have no wear that I can tell (no groves or even any marks). So now I have all new pads and new front rotors. I will take it to have it checked. I cannot think brand new rotors would be warped.

 

new rotors seldom are warped, but it is possible.

in fact, the used rotors may look great and still be warped.
I cannot tell warped by peeking under the wheel well.

you be smart to do the tests recommended.

 

A warped rotor especially in the rear can appear to be like new and still be warped. Resurface the rear rotors and report back.

 

quite the contrary, with my expireonce with brakes about 3 out of 10 new brak rotors purchaced were warped bad, and then 4 out of the remaining 7 were warped slightly. as for the warped front rotors, it depends on the vehicle and degree of the warp really, some times if will pulse the pedal, sometimes not, ive expirerienced it both ways.

 

Thaks to all who posted,,,,I feel so stupid,,,I put air in all tires(@ 38 lbs) so I would get some better milage and now no shaking,,,smooth as a babbys butt on stopping! Just goes to show check the simple things first.

 

good to see you got it fixed
