mechanically
hydraulically
pneumatically
none of these
a duct directs air towards the caliper for cooling while the vehicle is moving
caliper is covered with cooling fins
disc contains many small holes for optimum cooling performance
disc contains radial vanes between its rubbing surfaces for optimum cooling performance
wheel piston or cylinder
anchor pin
brake drum
wheel rim or axle
adjust the extent of brake pedal free play
boost the force applied to brake pedal
convert brake pedal force into hydraulic pressure
ensure that all the wheel brakes are supplied with the same amount of fluid pressure
enhances safety by serving two independent lines in a divided line brake circuit
enhances safety by activating the brakes using vacuum pressure in the event of brake fluid loss
supplies equal fluid pressure to each line of a divided line brake circuit, thereby preventing the brakes from dragging on one side
boosts the brake fluid pressure to reduce the force required to depress the brake pedal
