3. Responses when fluid is leaking

• A Secondary piston
• B Rear right
• C Front left

(1) In case of leaking from the primary system:

Since the fluid pressure on the primary side does not rise, the primary piston is pushed by the fluid pressure of the secondary piston and the tension of the piston spring until the end hits on the cylinder. The braking is performed by the fluid pressure on the secondary side.

• A Rear left
• B Front right

(2) In case of leaking from the secondary system:

The secondary piston does not produce fluid pressure, keeps moving forward until it contacts the end surface of the primary piston so that the primary piston is pushed under the same condition as an ordinary rod. Therefore, the braking is conducted by the fluid pressure on the primary side.
