Brakes were initially a mix of hydraulic (front) and mechanical (rear) with drums, replaced by a fully hydraulic brake setup from 1951 onwards on the hardtop coupe (saloon) with large diameter finned drums and vented wheels. This made for efficient anti-fade braking for the time, necessary to bring the vehicle to rest. Longevity The lack of factory rust proofing and styling that produced a multitude of mud traps led to rapid corrosion commonplace among many rushed post-war British designs. As a consequence of this and many Atlantics being broken up to provide spares for the Austin-Healey 100 very few examples survived into the 1970s, let alone the next century. In the UK today, it is estimated that fewer than 60 survive, half of them roadworthy.
