• Hydraulics

2
Hydraulic pressure is distributed equally in all
directions
3
Same line pressure to all wheels
4
The hydraulic pressure that results from
applying piston A is equal to what is applied
to piston B
5
The Hydraulic pressure is the same, but the
applied force can be changed by the piston size.
6
The amount of hydraulic pressure is determined by
dividing the force by the area of the piston
7
The area of the piston is determined by using the
formula
8

• Radius squared x Pie (3.14)

CBC Auto
9
The amount of force at the output piston can be
determined by multiplying the area of the output
piston by the pressure.
10
The caliper piston needs more applied force
without servo action

11

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

12
Brake Lines
13
Steel lines only Never Copper
14

• Styles of fittings

15
Flare nuts round off very easily
16
Steel tubing will kink easily when bending
17
Tubing bender in action
18
Styles of brake hoses
19

• Securing the brake hose

Hoses are like tires, and can separate between
the cord layers
