Automotive Brake System Hydraulics

Chapters Five in Both TextsFive in Both Texts JF

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
