Hi there,

You may have inserted a pad back to front, make sure that al the retaining clips are fitted correctly, check for and stones stuck up behind the backing plate.

Thats ok. What started was I pulled a trailer from ohio to NC and back to ohio. Then my brakes started a light squiling. So I put new pads on could my rotors be warped? Also there is now a rim on the outer edge of the Rotors do the pads have to wear into that gruve before they quit grinding

Hi there,

Glad to hear that the pads are right way around, as I have seen this happen and it is rather scary thing to see.

Now as for the rotors, that rim is an indication that the rotors are worn, There is a min thickness for brake rotors so you should check what thickness your rotors are and then allow a bit for machining. If they are under size you will have to replace the rotors, Why you ask. Because when the rotors become to thin they will not disapate the heat generated when braking and brake fade will become a problem also they will hot spot and tnat is what the squeel is. As for why there is that rim in the first place not all pads are excatly the same size and when the rotor starts to ware down (you may loose a mm or so with each set of pads depending on the compound used, the pads will conform to the track worn in the rotor and cut out quickly so that rim will get deeper with each set of pads. If the rotors are warped you will notice a vibration in the steering under braking (front rorors) or a pulsation of the brake pedal when braking (front & rear rotors)

Long winded I know, so check rotors for thickness and have machined if ok, otherwise replace rotors.
