BTA469 is a front brake disc designed for wire wheel variants of the Austin-Healey Sprite and MG Midget. It forms part of the front disc brake assembly, working in conjunction with the caliper and pads to convert kinetic energy into heat through friction. Using a worn, warped, or incorrectly specified disc can result in brake fade, judder through the steering, and extended stopping distances. Key Features Front axle fitment, specific to wire wheel hub configuration - not interchangeable with road wheel variants Designed to mate correctly with the wire wheel splined hub and associated caliper bracket Supplied as a direct OEM replacement to maintain original braking geometry and caliper clearance Discs should be replaced in axle pairs; inspect caliper seals, pads, and flexi-hoses at the same time Vehicle Fitment This front brake disc fits wire wheel equipped variants of the Austin-Healey Sprite and MG Midget - refer to the part title and your vehicle specification to confirm wire wheel hub compatibility before ordering.
