Allows for the assembly/disassembly of the brake caliper fixing screws when working on the braking system. Used mainly on the front and rear axles of heavy vehicles. Even the most stubborn screws are released with the blow of a hammer on the end of the wrench. All wrenches are equipped with a 3/4" square drive that also allows clamping, in combination with a torque wrench, according to the manufacturer's instructions. Warning: pay attention to the torque conversion formula marked on the wrench by means of a laser (necessary because of the lever's extension due to the type of construction) . It is no longer necessary to remove the lever of the steering control tie rod.
