Magnum 11-Piece Disc Brake Caliper Tool Set (1090)

Force brake pistons back smoothly without damaging the delicate inner seals or exterior dust boots. This comprehensive 11-piece disc brake caliper tool set provides the mechanical advantage needed to efficiently wind back stubborn brake pistons during pad replacements. It includes a heavy-duty reaction plate and a wide variety of precisely machined adapters to interface securely with the piston faces on most domestic and import vehicles currently on the road.
