Grinding sound coming from front end under braking of 99 Silverado???

    Hey all. I'm new to the site. I'm actually a domestic V8 car guy myself, but my mother-in-law's been having a problem with her 1999 Silverado 1500 2WD. Under braking it makes this GRINDING noise. I, being somewhat mechanically inclined, immediately attributed it to bad brakes (makes that commom metal on metal sound when pads are shot). Well, I pulled the calipers and pads did'nt look bad. Changed them anyways along with new front calipers as well. So basically an all new front brake setup. Drove the truck and the problem is still there! Can anyone point me in the right direction on this one?? THANKS.

    When you had the front brakes apart did you check the hub bearings? If so how'd they feel?

    it could be coming from the front metal plate or from the back and the noise could transfer and check the wheel bearings that would do it to

    Well, it would have paid to have someone stand outside the truck, or myself, and LISTEN externally to see where the noise was coming from. I put COMPLETELY new brakes on the front (rotors, pads, and calipers). No change. Had my wife drive the truck as I stood outside it. Come to find out it's the rear right brake!! Pads look SHOT on both sides. Think I'm going to do pads and rotors and new calipers on the rear as well. Rather have all new brakes the whole way around. Got all the parts yesterday to do the rear. Probably get a start on it this afternoon. Yeah :)
