| My original set of inner brake pads were 75% worn per dealer repair shop at 29,672 miles. the outer pads were fine. the rotors were approaching end of life. i had them replace the pads at this time. the dealer did not offer to cover them under warranty. at 30,945, 1273 miles later, i took the car back for another brake inspection. at this time they found that the rotors were rusted and pitted, not normal wear. they replaced the pads and the rotors under warranty (seems strange it wasn't warranty before?!?!?). now at 65k miles i took the car in for a brake inspection at a repair shop. they said the front pads and rotors were shot and they had about two weeks left of city driving left. my husband replaced both the pads and the rotors this weekend. the inner pads were worn down to the rivets that hold the pad to the mounting surface. the outer pads were hardly thinner than the brand new pads out of the box. so this leads me to believe that gm has an issue with the brake calipers not applying pressure evenly. i have seen complaints like this on this website referring to the same problem. *nm | |||

| The brakes on my 2001 pontiac montana wear out prematurely. i had to replace the front pads 3 times in 2 years. in each case the inboard pad had excessive wear and the outboard pad did not. i have been informed the wear indicators are on the outboard pads, this presents a lack of warning to the driver that the brakes are in need of service. the calipers have been replaced once and this did not solve the problem.*jb | |||
