Product Details

Raybestos R-Line focuses on service replacement parts for everyday brake repair, and the 97831R follows that approach with the dimensions and lug pattern needed for specific drum brake applications. When searching for a brake drum for a Toyota, Honda, or other vehicle using this size specification, matching the outside diameter, depth, nominal drum diameter, and lug-hole layout is essential for proper fitment. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Brake drum scoring or wear that affects braking surface contact
• Out-of-round drum conditions that can cause pedal pulsation
• Excessive brake noise from worn drum surfaces
• Reduced rear braking performance from a damaged drum
• Service replacement for a drum brake system requiring this size and 6-lug pattern

Installation Notes

Verify the drum dimensions, lug count, and thread pitch against the original part before installation. Measure the existing drum and confirm the vehicle’s brake configuration, especially on Toyota and Honda applications where exact drum size matters. Clean the hub mounting surface, inspect related brake components, and check for proper drum-to-shoe clearance after installation. The part number 97831R should be matched to the vehicle’s brake specification, not just the wheel bolt pattern.

Quality Assurance

Raybestos R-Line replacement parts are cataloged for service use with application-specific dimensions and fit requirements. Confirm all measurements and interchange references before ordering to ensure the 97831R brake drum matches the intended repair.
