BRAKE ADJUSTER TAPPET (see 17H7620 for full cheaper kit)

Genuine AP wedges (see kit 17H7620 which has 2 wedges plus adjuster screw). These are the little wedges that fit in the brake adjuster screw bracket on the rear brake drum to adjust the brake shoes. The adjuster is 17H7619 but all 3 parts are available in a kit as 17H7620 which is a more viable purchase.
