Students have asked these similar questions

The purpose of the master cylinder is to ______. a. generate the hydraulic pressure needed to apply the brake mechanisms b. automatically pump the brakes during panic stops c. supply mechanical force to the brake mechanisms d. All the answers are correct. The purpose of a pressure differential valve is being discussed. Technician A says it alerts the driver if pressure is lost in either portion of a dual braking system. Technician B says it provides the needed pressure balance between the front and rear brakes. Who is correct? a. A only b. B only c. both A and B d. neither A nor B In a diagonal split brake system, how would the vehicle brake in the event of a failure? a. One front wheel and its rear wheel will brake. b. One front wheel and the opposite rear wheel will brake. c. Only the front wheels will brake. d. All four wheels will have half the total braking force.

The advantages and disadvantages of disc brake systems are being discussed. Technician A says that disc brakes are more likely to develop brake fade and water fade. Technician B says that reduction of mechanical fade and gas fade is an advantage of disc brakes. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor B 2. The operation of disc brake systems is being discussed. Technician A says that composite rotors were developed to save weight. Technician B says that a fixed rotor assembly is part of the hub. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor B

When replacing brake pads on a vehicle: Technician A works on one wheel before beginning work on an-other. Technician B uses a minimum of 52 psi of air pressure to force the piston from the caliper housing. Who is correct?
