Integra L4-1678cc 1.7L DOHC (VTEC) FI (1992)
(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 per formed by the fluid
pressure on the secondary side.
(2) In case of leaking from the secondary system: The secondary piston does not produce fluid pressure, keeps moving ahead, hits on 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.
