A rear brake with an integral hub and brake drum. The riveted lining on the leading (rear) shoe is positioned off centre in the direction of wheel rotation.
Check drum brakes at least every six months, 6,000 miles or 10,000 km, or as recommended in the car’s normal service schedule. Look for worn brake linings.
Later cars often have a plugged inspection hole in the backplate. On other cars you need to remove the drum.
Linings may be riveted or bonded to the brake shoes. With riveted linings, replace the shoes well before the lining wears down to the level of the rivet heads. Exposed heads score and ruin the brake drums.
