Dynamic Friction Company Drum Brake Adjuster P/N:372-40009
Keep your rear drum brakes properly adjusted with the Dynamic Friction Company Drum Brake Adjuster, part number 372-54020. This drum adjuster kit takes up shoe-to-drum clearance as the linings wear, helping maintain proper adjustment for a firm, consistent pedal. It's cataloged for the rear right position and is supplied as an axle kit — not sold per side — and fits many vehicles, among them the 1995-2009 Ford Ranger, 2002 Jeep Liberty and 2001-2009 Mazda B2300 (see the Buyer's Guide tab for the full list).
Worn or seized adjusters can leave the shoes too far from the drum, causing a low or fading pedal and uneven lining wear. If a failed adjuster is the cause, this kit replaces it. Sold as an axle kit, not per side.
