Master Cylinder

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

• When the brake pedal is depressed, pressure is applied by mechanical linkage to the primary and secondary piston.
• Brake master cylinder pistons apply hydraulic pressure to the two 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.
