- Technician A says that the discard dimension of a brake drum is the drums allowable machining dimension. Technician B says that the discard dimension is the allowable wear dimension. There must be 0.030 inch left for wear after machining. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTechnician A says that fixed calipers use a piston on each side of the rotor to apply the brakes. Technician B says that sliding calipers typically use only one piston or pistons on one side of the rotor. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTrue or False? The name duo-servo drum brake is derived from the fact that the self-energizing force is transferred from one shoe to another with the wheel rotating forward.arrow_forward
