One problem related to brake disc caliper has been reported for the 1996 Chevrolet Tahoe. The most recently reported issues are listed below.
Calipers operate improperly, causing uneven pad wear/premature wearout. One pad (on the same caliper) would be completely gone (down to rivets)and the other having more than half its life left. This happened on both front calipers. This caused excessive wear to rear shoes because the front brakes were not fully opetational and the rear brakes were primarily stopping the vehicle. The dealer replaced pads first, later did a caliper rebuild kit, later after vehicle out of warranty, refused to replace calipers, or fix problem. I had calipers replaced at my expense (bendix calipers). I am currently waiting to see if this fixes the problem. Have contacted gm and they now refuse to fix the problem as vehicle is out of warranty(even though problem has occurred repeatedly since vehicle was new).
