    Your rear brake linings might be "glazed" and don't grip well anymore, and/or no longer fit well inside the drum. If the brake shoes are not too expensive, you may need to replace them, or at least remove them and the drums, and have the shoes clean, then "arced" to the drums by a brake shop.

    this is a reply to mr shiftright.
    thanks is there a way to tell if they are glazed. the drums are very smooth , no ribs,no groves . linings have about 15000 miles on them and look very good.
    sorry about reply this way not sure if this is the correct way this is my first time using this type of site. seems to be great info for the back yard mechanic.

    Yes you did things perfectly in answering me.


    Glazing is noticeable as a shiny surface on the brake linings. You should also check that the adjuster is not frozen, or the cables fraying, thereby stretching when you apply the hand brake. You might have to have the brake drum true-ness measured with a run-out gauge. If the drum is out of round, you aren't going to get good brake shoe contact. The brake drum is out of round if there is a variance of 0.015 mm (0.0006 inch)
