Esteem GLX Sedan Plus L4-1.8L (1999)
One-Circuit Operation (Secondary Chamber "b" Circuit Failure)
In this case, the leftward movement of the piston "A" has but little effect in causing the fluid pressure to rise in the chamber "a" in the beginning,
because the initial rise of the fluid pressure causes the piston "B" to promptly yield and move to the left. However, when the forward end of the
piston "B" comes to the head of the cylinder and stops there, the leftward movement of the piston "A" becomes effective. Thus the fluid pressure is
produced in the chamber "a" and it acts on the right front wheel brake and left rear wheel brake. The above image shows secondary piston "B" at
half.
