The three pentagon brake sockets European vehicles call for: a 19mm for Peugeot, Citroën, and Renault (Bendix brakes), a 14mm for Opel/Vauxhall (Astra G/Zafira) and Smart, and a 1/2" pentagon brake socket bit for Girling brakes. Chrome-vanadium construction for brake work standard hex sockets simply can't do.
