    New Brake Pad Composition

    At 27500 miles, developed an occasional squeaking from rear wheels: diagnosed as brake pads - and will be replaced under warranty with new composition pads - on order at the moment. Original pads have been redesigned, apparently. Anyone else hear of this?

    That's the first I've heard of redesigned brake pads. I'm glad they're replacing them under warranty. This should help with your problem. However, personally for me I'm not sure if new composition brake pads are a good thing or bad thing. Mine make no noise whatsoever, stop smoothly and produce absolutely no brake dust. I can't ask for more than that. I just hope the new design is as "dustless" as the originals.

    I always thought brakes "squeaking" was an intentional indicator that you need new brakes. At 27,500 miles that might be the case. Did they say how worn your brake pads were?

    I agree with you completely - I really like the dust-free and very smooth braking. I thought I needed new pads too - and was surprised when they said they were in good shape - just needed some new formulation. They said a TSB was out on it - but I couldn't find one. I will ask tomorrow when I go in for the work.

    I'm a little confused. I thought this was a newly formulated brake pad. What do you mean by "new formulation"? Is this some treatment done to the existing brake pads?

    Re: New Brake Pad Composition

    revising pads materials is not uncommon, especially for resolving squealing or corrosive brake dust (yes, chrome hates that dust!) Chrysler/Volvo have done it for years. Squealing when coasting, IS a warning of worn pads as SUBE states. I'm sure they are just replacing pads (maybe even with same exact same type, with a rotor cut!) to nicely accommodate the customer? Never heard of existing pads being tampered with, in any way. Just comm confusion I suspect..

    Rear brakes on a FWD oriented sled should last 50K miles minimum, as the front brakes do 80% of the average braking on such vehicles. AWD makes little diff as the chassis engineering is same.

    Interesting info though.... keep us up!

    Re: New Brake Pad Composition

    Picked up car today. Here's what they did under warranty: "Replace rear brake caliper brackets and pads. Verified noise coming from rear brakes. Bulletin found to replace the rear pads and brackets. Rotors too thin to resurface. Replaced rear brake caliper brackets, pads and rotors."

    The service manager told me that they had to order "the new, redesigned and reformulated brake pads along with the new caliper brackets". Mileage: 27,635 miles.

    I'm happy it was under warranty. Love the car !!

    Re: New Brake Pad Composition

    So, after above repair, I now have what sounds like a couple of "clunks" coming from rear drive train area (differential, axle ??) upon starting from a stop. Happens during acceleration from stop - but not always. Seems worse in morning - seems to go away when warmed up. Feels like something is slipping - and then engages suddenly, maybe two or three times - then is quiet as speed goes above about 25 or 30. Also, noticed an occasional scuffing noise coming from rear when turning sharply at slow speeds, as when parking. Both of these new noises began at the same time, a day or so after brake work noted in previous post. Coincidence ? Related ? Any thoughts ?

    SRXCool,
    I am currently having the same problem you had & can't get the dealership to pin point the squeal. I have less than 26,000 miles, originally was told I needed my front rotor resurfaced. I did that to include new brake pads even though the metallic ones that was on it had 9mm of padding. This didn't fix the problem nor was it covered under warranty. Took it back & was told the back rotor need resurfacing. I made such a fuss that they resurfaced the back but I still have the squeaking when going down an incline and when lightly applying the brakes. By any chance do you have detailed info on the bulletin you mentioned?
    As far as the clunking, mine was also making that clunking sound. The dealership replaced my fuel tank per a bulletin.

    Give everything a few days to settle/break in. IF it still happens after a week, take it back in.

    I disagree with Adam about waiting, I would take it back and have it checked asap.
