reducing drum brake drag
I've noticed a similar issue on my '95 Metro. One indication of the problem is the amount of travel of the lever or pedal when setting the parking/emergency brake. My 92 Metro brake lever clicks 5+ to set the brake. My 95 just 3 clicks. There is a problem in the automatic brake adjuster that is allowing it to set the brake shoes so that they don't retract completely off the drum when not using the brakes. I've not gone back in to fix it but I think the adjuster is pretty simple star wheel and lever. If the lever is bent a little and engages the star wheel at the wrong point it could cause the brake to adjust too tight. I've noticed my mileage has suffered, I hope this improves things.
