Review on Titan 15614 1/2-Inch Drive x 14mm Hex Bit Socket: Precise Tool for Versatile Mechanics and DIY Projects by Todd Phillips

Required to replace brake pads on many Mercedes/SUVs and other foreign vehicles. Only in one store they were usually transported, but it was not available. They said the Mercedes employees would come and buy them all. Mercedes service departments make money replacing discs and brakes. After I decoded the automatic parking brake, the wheel was removed and we used a hex wrench to loosen the caliper. It worked like a charm and all I had to do was buy 4 TRW brake pads - no squeak/squeak = complete brake replacement for less than $100! If you don't have Hex 11, you can't switch brakes.
