    Rear drum/shoe wear check?

    Had my ATF and coolant flushed at a Mazda dealer the other day. As I was leaving, they give me this "Full Circle" report that says that the rear brakes are getting low.

    Now I have rear drums and 46K miles--I thought these aren't supposed to go until 70-90K?? When I came in for brake service (replacing fronts) at 40K, the tech at that same dealership said that the rear brakes were looking fine.

    I asked the service manager--did you take off the rear wheels and open the drums to check the brake shoe wear? She said: "no, we have a tool that we can check the rear shoe wear with."

    Is there really a tool that allows you to check rear brake shoe wear without opening up the drum?? How can I validate her claims?

    Anyway, she said that it would be $190 for rear brake service: replace shoes and resurface drums. $190 my effing ass! They are not even replacing the drums!

    Re: Rear drum/shoe wear check?

    According to the FSM, under the heading Rear Brake (Drum) Inspection, inspecting the remaining thickness of the lining requires removal of the brake drum in order to measure it. The thickness can be no less than 1.0 mm (.039") or the brake shoes must be replaced.

    Next, the inner diameter of the drum must be measured with an inside caliper. Maximum allowable diameter is 201.5 mm (7.933"). The drum must also be inspected for uneven or abnormal wear and repaired or replaced as necessary.

    Nowhere in the FSM does it indicate that these measurements can be carried out without removing the drum nor is any special service tool listed that could perform this supernatural feat.

          Fixed the double post.

          I've replaced my rear shoes twice in the lifetime of my car, and it's at 80,000 right now. I guess it depends on your driving style.

            Holy old-post batman!!

            All late and wrong, but its bull****! Some have small grommets in the rear so you can view one of the shoes, but its not that accurate. Brake dust makes it hard to tell, so the best bet is to just pull them off. There is a tool to tell you how close you are to needing shoes and usually consists of 6 colored pieces but only when the drums are off.
