Detailed Description

Centric Premium Brake Drums are engineered to match original equipment specifications, helping maintain correct drum geometry, mounting fit, and braking surface dimensions. Part number 122.44042 uses a 5-bolt pattern, a 3.937 in. bolt circle diameter, and a floating mounting design, making it a direct rear brake drum choice for 2003-2008 Pontiac Vibe and 2003-2008 Toyota Matrix applications. This part cross-references Raybestos Brakes 9725R and Anchor 9725 for the same application.

The drum measures 2.173 in. in height, has a 2.165 in. hub hole/register, and does not use outer cooling fins. These specifications matter when replacing a worn rear drum on a Pontiac Vibe or Toyota Matrix, especially when the goal is to restore consistent pedal feel, reduce brake noise from worn drum surfaces, and correct braking issues caused by scoring or out-of-spec wear.

What This Brake Drum Helps Address

• Rear brake pulsation caused by an out-of-round drum
• Scoring or wear on the friction surface
• Reduced braking consistency from excessive drum diameter wear
• Noise from a damaged or heat-affected rear drum
• Fitment issues when replacing a worn OE-style drum on a Toyota Matrix or Pontiac Vibe

Installation Notes and Tips

Verify rear axle fitment, bolt circle, and drum diameter before installation. Measure the existing drum and compare it to the discard diameter of 229.60 mm (9.039 in.) to confirm replacement is needed. Inspect shoes, hardware, wheel cylinders, and the backing plate for wear or contamination before installing the new drum. For best results, clean the friction surface and confirm the drum seats fully on the hub register.
