This brake drum is a core component of the rear drum braking system fitted to early Land Rover Series 3 and Defender models. It provides the friction surface against which the brake shoes press to generate stopping force; a worn, scored, or cracked drum reduces braking efficiency and can cause uneven or pulsating braking. Correct replacement restores the designed contact geometry between drum and shoe, maintaining consistent stopping distances. Key Features Cast iron construction providing the required hardness and heat dissipation for drum brake operation Machined inner braking surface dimensioned to match the original Series 3 and early Defender rear axle specification Direct OEM-equivalent replacement - no modification required for fitment Brake shoes should be inspected and replaced alongside the drum if lining wear is uneven; drums are typically replaced in axle pairs Vehicle Fitment Fits Land Rover Series 3 88" models from launch through to June 1980, and Defender 90 models from 1986 up to chassis number KA930455.
