Keep your rear drum brakes retracting cleanly and quietly with the Carlson Drum Brake Adjusting Spring Kit (H446). It drops in as a direct-fit replacement for the listed Ford applications, including the 1976-2002 Ford E-250 Econoline, 1977-2000 Ford E-350 Econoline, 1980-1999 Ford F-250 and 1976-1997 Ford F-350 (all engines) — see the Buyer's Guide tab for the full list.
- Kit contents: two return springs that pull the brake shoes back off the drum after each stop.
- Materials: the adjuster material is steel, built to high tolerances with quality materials.
- OE-quality: matches Original Equipment (OE) quality specifications.
- Proper shoe movement: fresh springs help keep everything moving at the proper intervals, supporting longer brake-shoe life and helping minimize brake drag.
Return and adjusting springs lose tension over time; when they weaken, the shoes can drag and let noise and extra heat build up in the drum. Installing fresh springs helps the shoes retract and reposition correctly. If worn springs are the cause of drag or noise on your vehicle, this kit replaces them.
