Brake Master Cylinder

The brake master cylinder is a dual-piston type. The brake master cylinder operates as follows:

• When the brake pedal is pressed, pressure is applied by a mechanical linkage to the primary and secondary pistons.
• Brake master cylinder pistons apply hydraulic pressure to the 2 hydraulic circuits.

The brake master cylinder consists of the following components:

• brake master cylinder reservoir
• brake master cylinder body
• primary piston
• secondary piston
• snap ring

Whenever the brake master cylinder is removed from the brake booster, new nuts must be installed.
