- While discussing quick take-up master cylinders: Technician A says that this design allows for increased braking power. Technician B says that this design is only used on drum brake systems. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhile discussing what affects the amount of pressure exerted by the brakes: Technician A says that the shorter the line, the more pressure there will be. Technician B says that braking force will increase if the size of the pistons in a master cylinder are increased. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhile discussing the effects of overtorquing wheel lugs: Technician A says that this can cause the threads of the lugs and/or studs to distort.
