Detailed Description

The Raybestos R-Line H446 is a rear drum brake adjusting screw spring used in drum brake assemblies that rely on a functional adjuster mechanism to maintain shoe-to-drum clearance. It is listed for a wide range of Ford rear drum brake applications, including 2003-2006 Ford E-250, 1976-2002 Ford E-250 Econoline, 1987-2000 Ford E-350 Econoline, 1987-2000 Ford E-350 Econoline Club Wagon, 1999-2000 Ford E-350 Super Duty, 1980-1999 Ford F-250, and 1987-1997 Ford F-350 rear brake setups. This part cross-references Carlson H446 for the same application.

If you are searching for a rear drum brake adjusting screw spring for Ford E-250, E-350, or F-250 rear drum brakes, H446 is the part number to verify against your existing hardware.

What It Helps Fix

• Loose or inconsistent rear drum brake shoe adjustment
• Worn or missing adjuster spring tension in the drum brake assembly
• Brake shoe drag caused by poor adjuster return or positioning
• Uneven rear brake performance during drum brake service
• Need for a replacement spring during Ford rear brake hardware repair

Installation Notes and Tips

Confirm rear drum brake shoe width and brake drum size before ordering. This part is listed for applications using 12" x 3" drum brakes and select 12" x 2-1/2" rear drum brake setups on Ford trucks and vans. Match the existing adjuster hardware and verify the part number H446 against the vehicle’s brake assembly before installation. For best results, inspect related drum brake hardware during service and replace any worn adjuster components at the same time.

Quality Assurance

Raybestos brake hardware is cataloged for service replacement use, and the R-Line designation identifies the product line for everyday brake repair applications. Verify fitment by year, make, model, and rear brake configuration before installation.
