Just for MINI; One of two return springs, per wheel, for Mini single-leading front drum brakes and all 10" Mini rears. This is the one with the coil in the center of the spring. A good mechanic will replace the pull-off springs (17H7621 & 17H8092) when installing new shoes. The return springs rust and fatigue over time and may have been damaged by improper installation in the past. <br>For Sprite and Midget applications, use two per car, one each on the bottom of the rear drums.
