EBD, short for Electronic Brake-force Distribution, as the subsystem of ABS, is designed to automatically modulate the brake force on the front wheels and the rear wheels according to the load of the car, the condition of the road and the adhesion between the tire sand road surface in order to get more balanced and closer to the ideal brake force distribution．

Brake caliper contains one or more pistons which transmit the brake force hydraulically to the disk．

______ utilize liquid to transfer force from the driver’s foot to the brake shoes. A: Disc brake systems B: Drum brake systems C: Hydraulic brake systems D: Air brake systems

what is the purpose of the brake hoses in the brake system?（ ） A: they add friction B: they add flexibility C: they add air flow D: they add brake force

Between the brake pedal and the master cylinder is the （ ） which increases the brake force to make the car slow down or stop with less effort. A: brake booster B: brake caliper C: brake drum D: wheel cylinder

Service brake needs higher braking force than the emergency brake.

When the driver applies the brake, the control device will force brake shoes or pads against the rotating brake or discs at wheels. A: devices B: linings C: drums D: pads

Brake booster mounted on the firewall between the brake pedal and master cylinder increases the force applied to the pistons in the master cylinder so that the car can stop with less effort．

________ is comprised of a brake disk, brake pads and a brake caliper. A: Emergency brake B: Disk brake C: Drum brake

Disk brake is comprised of a brake disk, brake pads and a brake caliper (see Fig.5-3).
