Tech B says that a drum brake operates by clamping friction materials to the outside of a drum. - Answer- Tech A Tech ! says that an antilock brake system (ABS) allows the front wheels to be steered during a panic stop. Tech B says that ABS sensors apply or release hydraulic pressure to the wheel brake units during ABS brake events. - Answer- Tech A Tech A says that friction brakes can fade due to overheating of the brake lining. Tech B says that friction brakes can fade due to overheating of the brake fluid. - Answer- Both A and B Tech A says that kinetic energy is created during braking to stop the vehicle. Tech B says that kinetic energy is converted to heat energy during braking. - Answer- Tech B Tech A says that light-duty service are typically applied hydraulically. Tech B says that light-duty parking brakes are typically applied hydraulically. - Answer- Tech A Tech A says that the brake pedal uses leverage to multiply foot pressure. TEch B says that
