Hyster Forklift S&H25 35XL service manual
- The master cylinder has a housing, a piston with two ring cups, a return spring and a check valve assembly. The reservoir for the fluid is separate from the master cylinder. When the brake pedal or inching pedal is pushed, the push rod moves the piston assembly.
- The primary cup forces the brake fluid through the check valve to the wheel cylinders. The secondary cup keeps the fluid that is above the primary cup in the master cylinder. When the brake pedal is released, the return spring pushes the piston assembly back against the retainer washer. The return springs for the brake shoes force the fluid that is in the wheel cylinders back through the lines to the check valve. The pressure in the lines moves the check valve from its seat.
- The fluid flows around the check valve to the master cylinder bore. When the brake pedal is released quickly, the return spring moves the piston faster than the brake fluid can flow around the check valve. To prevent cavitation, holes are drilled in the piston. Fluid from the inlet port flows through the holes. The fluid bends the lip of the primary cup and permits fluid to enter the pressure chamber. The check valve assembly permits fluid from the pressure chamber to flow to the lines when the brake pedal is pushed.
- When the pressure in the pressure chamber is greater than pressure in the lines, the check valve will open. When the brake pedal is released, the pressure in the lines is greater than the pressure in the pressure chamber. The check valve assembly then moves against the spring pressure to permit fluid to return to the pressure chamber. The check valve assembly returns to its seat when the pressure in the lines decreases to less than the spring pressure. This action keeps a low pressure in the INTRODUCTION FIGURE
