Hydraulic brakes use liquid to transfer force and stop vehicles effectively. This model demonstrates the concept using syringes, tubes, and a DC motor.
- Brake Pedal Action: A syringe acts as the brake pedal. When pushed, it forces liquid (water or oil) through a connected tube.
- Force Transfer: The liquid, which cannot be compressed, transfers the force to another syringe acting as the brake cylinder.
- Stopping the Wheel: The second syringe presses on a rotating disc or wheel powered by the DC motor. The friction slows down or stops the wheel.
In this post article we write about making of the hydraulic brake system working model – physics pascal science project – disk brakes
simple step-by-step guide to create a hydraulic brake system working model using 4 syringes, a DC motor with a cardboard wheel, and cardboard
Materials You’ll Need:
- 4 syringes
- Plastic tubing
- DC motor
- Cardboard sheets
- Craft knife or scissors
- Hot glue gun and glue sticks
- Craft supplies for decoration (markers, stickers, etc.)

- Prepare the Base:
- Cut a cardboard sheet to use as the base of your model.
- Create the Brake Pedal:
- Cut a piece of cardboard to create the brake pedal. This will be the part that you press to apply the brakes.
- Attach the brake pedal to the base using a small piece of cardboard as a hinge.
- Assemble the Syringe Assemblies:
- Group two syringes together for each side of the model (left and right wheels).
- Attach the syringes vertically to the base using hot glue. These syringes will act as hydraulic cylinders for the brakes.
- Connect the Syringes with Tubing:
- Use plastic tubing to connect the two syringes on each side of the model.
- One syringe will act as the master cylinder (brake pedal side), and the other as the slave cylinder (wheel side).
- Create the Wheel and Attach DC Motor:
- Cut a cardboard circle to create the wheel.
- Attach a DC motor to the base near the wheel using hot glue. The motor’s shaft should be positioned to touch the cardboard wheel.
- Connect DC Motor to Syringe:
- Attach a piece of plastic tubing to the motor’s shaft.
- Connect the other end of the tubing to the master cylinder syringe.
- Operate the Model:
- Gently press the brake pedal (cardboard piece) to simulate applying the brakes.
- As the brake pedal is pressed, the DC motor turns the cardboard wheel, which applies pressure to the master cylinder syringe and transfers fluid pressure to the slave cylinder syringe, slowing down the wheel’s rotation.
- Decoration:
- Decorate the model with craft supplies to make it visually appealing.
This model effectively demonstrates how a hydraulic brake system works, where pressing the brake pedal generates pressure in the master cylinder, which is transferred to the slave cylinder to slow down or stop the wheel’s rotation. It also showcases how a DC motor can be used to simulate the braking action.
