  25. WORKING OF HYDRAULIC BRAKE BRAKE RELEASED WHEN THE DRIVER RELEASES THE PEDAL , THE RETURNING FLUID OPENS THE CHECK VALVE AND SLOWLY RE-ENTERS THE MASTER-CYLINDER.A SPRING CLOSES THE VALVE TO LEAVE A SLIGHT PRESSURE IN THE LINE

  26. WORKING OF HYDRAULIC BRAKE BRAKE OFF . THE RETURNING FLUID FORCES THE MASTER CYLINDER PISTON BACK UNTIL THE RESERVOIR PORT IS UNCOVERED . THE SPRING IN THE WHEEL CYLINDER KEEPS THE BRAKE SEALS IN POSITION NEXT TO THE PISTONS.
