Brake Master Cylinder: Description and Operation
Master Cylinder Description (With ABS)
Master Cylinder
The master cylinder assembly consists of the two following components:
^
An aluminum body
^
A plastic brake fluid reservoir
Internally, the master cylinder houses the following components:
^
A primary piston
^
A secondary piston
^
Three piston cups
The master cylinder is mounted on the brake booster assembly.
When the brake pedal is depressed, the primary piston compresses the volume of the primary chamber, increasing the hydraulic pressure in the chamber.
This pressure, along with the return spring force, causes the secondary piston to compress the volume of the secondary chamber.
The hydraulic pressure in the primary chamber acts on the left rear brakes and the right rear brakes.
The pressure produced in the secondary chamber acts on the right front brakes and the left front brakes.
Master Cylinder Reservoir
The reservoir attaches to the top of the master cylinder. The master cylinder is located under the hood on the left side of the bulkhead. The reservoir is
constructed of transparent plastic. The reservoir is marked with the MAX level on the outside.
