Looking for abit of trouble shooting on my ebrake. I get some rub on the transmission brake drum regardless of adjuster setting. Since a picture is worth a thousand words, a video must be worth at least 2,000. That, and I wanted to take advantage of the cool movie embed feature (thanks Thompson!) and so have posted a quick video of the drum rub.
In the video, the first 2 clicks of the adjuster are from full lock of the brake drum. The second two clicks give a "no-rub" condition of the brake drum...until you apply the brake, release, and check. At that point, you get the rubbing back. It doesn't matter how far you back the adjuster out, the rubbing remains.
Does this suggest the drum is out of round, or somehow the expander isn't retracting. The expander was disassembled, cleaned, and greased up. The pistons do expand and contract when I pull the brake and put my fingers on the piston to check them. Movement of the expander assembly is minimal and the expander unit shaft feeding in to the anchor plate is fully releasing. Also, the adjuster unit is the NEW style which means you can't mix up the adjusting plungers.
Is some minor rub of the e-brake shoes normal? I would think no. Thanks.
