Automotive Brake System Hydraulics

Hydraulic pressure is distributed equally in all directions
Same line pressure to all wheels
The hydraulic pressure that results from applying piston “A” is equal to what is applied to piston “B”
The Hydraulic pressure is the same, but the applied force can be changed by the piston size.
The amount of hydraulic pressure is determined by dividing the force by the area of the piston
The area of the piston is determined by using the formula:
Radius squared x Pie (3.14) CBCAuto
The amount of force at the output piston can be determined by multiplying the area of the output piston by the pressure.
The caliper piston needs more applied force without servo action
The applied pressure can be raised or lowered by piston size The applied pressure can be raised or lowered by piston size
Brake Lines
Steel lines only Never Copper
Styles of fittings
Flare nuts round off very easily
Steel tubing will kink easily when bending
Tubing bender in action
Styles of brake hoses
Securing the brake hose
Hoses are like tires, and can seperate between the cord layers
