RETNO/Girling Style Front Brake Caliper

The Retno 18/4 Endurance Front Brake Caliper is a reproduction of the legendary Girling-style brake caliper used on some of the most iconic sports racing cars of the 1960s. Precision-manufactured from high-strength 356-T6 aluminum alloy, these calipers combine authentic period appearance with modern manufacturing quality and reliability.
