grinding noise ???
have a 1998 z71 k1500 that i have inspected the brakes on and they are all perfect.....that being said, intermitantly I get a grinding noise that seems to be coming from the front brakes only when i brake at slow speeds to a dead stop,, but only some of the time. I cant tell exactly where it is coming from, and it is really driving me crazy. also , when i first start driving it doesnt seem to happen but after a few minutes into driving it starts. it has been getting a little more apparant over the past 6 months..
someone please help, DB

Re: grinding noise ???
Are the calipers floating freely on the brackets/pins? Were the caliper pistons clean or pitted/corroded when they were removed for inspection?
If you drive on gravel or loose stone roadways, there may be sand, pebbles, or other contamination in the pad areas or causing the caliper to stick. I saw a trailer light connector lodged in a caliper bracket once, binding the caliper and causing pulling from the opposite side. Strange things can get in there.

Re: grinding noise ???
i did tear down both front brake assmblys, the calipers looked good and floating, the pads had some surface cracks in them. I went offroading a couple weeks ago and did get into a lot of water, maybe that got the pads screwed up. any ideas?
thanks in advance

Re: grinding noise ???
Thanks Guys-
I Took The Assembly Apart Again And Looked At Them Closer, Both Sides This Time. On Both Sides The Cracks In The Pads Were Obvious And The Pads Also Looked Burned. I Changed Them Out, And It Stops Smooth And Quiet Now....those Old Pads Are Going Back To The Store For A Refund (2 Yr Waranty)  Thanks For The Replys Bitt
