3
Hydraulic pressure is distributed equally in all
directions
4
Same line pressure to all wheels
5
The hydraulic pressure that results from
applying piston A is equal to what is applied
to piston B
6
The Hydraulic pressure is the same, but the
applied force can be changed by the piston size.
7
The amount of hydraulic pressure is determined by
dividing the force by the area of the piston
8
The area of the piston is determined by using the
formula
9

• Radius squared x Pie (3.14)

CBC Auto
10
The amount of force at the output piston can be
determined by multiplying the area of the output
piston by the pressure.
11
The caliper piston needs more applied force
without servo action

12

• The applied pressure can be raised or lowered
  by piston size

13
Brake Lines
14
Steel lines only Never Copper
15

• Styles of fittings

16
Flare nuts round off very easily
17
Steel tubing will kink easily when bending
18
Tubing bender in action
19
Styles of brake hoses
20

• Securing the brake hose

21
Hoses are like tires, and can seperate between
the cord layers
