This tutorial will show you how to make hydraulic brakes science model. Hydraulic brakes are the braking system’s mechanism used to brake fluids like diethylene glycol. The hydraulic brakes are widely used in automobiles and greatly apply hydraulic fluids. These brakes are functionalized by taking the fluid pressure and breaking them. 


For making the hydraulic brake at home for your science model, we need some basic material which is listed below; 


  • DC Motor 
  • Battery 
  • Connector
  • Switch
  • Hot glue gun 
  • Scissor/Cutter
  • Fevicol
  • 4 Syringe 
  • 2 Syringe pipe 
  • Compass


  • Cardboard (For base and for cut parts) 
  • Colored paper 
  • Mustard oil 

Steps To Make Hydraulic Brakes Science Model

Step 1: First, take cardboard and draw four circles in it with the help of a compass. 

Step 2: Now, cut the circles through a cutter or scissor and paste them one upon another with the fevicol. 

Now paste a blue colored paper up to it and make a small hole at the center of it. 

Step 3: Connect DC motor with switch, battery connector, and wire. Attach the DC motor at the center.

Step 4: Take the base cardboard, cut a small rectangular-shaped cardboard piece, and paste it into the base with the fevicol (As shown in the picture). 

Step 5: Paste the motor on the top of the board and battery on the downward of the board.

Step 6: Take the two board rectangular pieces and attach them as shown in the picture. 

Step 7: Paste that on the base cardboard as shown in the picture.

Step 8: Now, take mustard oil, two syringes, and two syringe pipes. 

Step 9: First, take two syringes and fill the syringe with oil. 

Now attach both syringes to the ends of the pipe and secure them with the hot glue gun. 

Step 10: Now attach the one end of the syringe at the pole in the base cardboard with the help of a hot glue gun, as shown in the picture.

Step 11: Now, cut two triangular-shaped small cardboard and paste them into the base cardboard.

Now, do the same process with the other two syringes and paste them in the triangular shape as shown in the picture. 

Step 12: Now, when one puts on the switch, the roller between starts to rotate and pushes the syringes, the roller stops due to the pressure. 

Hydraulic Brakes Science Model


Hydraulic brakes transfer the mechanical energy to stop the roller. This tutorial will help students and youngsters to understand the working principle and construction of hydraulic brakes. 

Students can also construct the hydraulic brakes using other waste materials easily available at home. 

Things To Remember

  • You can use recycled or old leftover cardboards and colored papers 
  • Be secure or wear safety gloves when using the hot glue gun. 
  • Use less glue; otherwise, it’ll destroy your model. 
  • Be secure when using the cutter or scissors.
