  • - balls metal;
  • - copper tube;

  • - car camera.

The spring will be compressed by pressure from above, which will open the valve. Next, you need to insert the valves into the holes and put them on with epoxy glue.
Next you need to take a piece of the camera car. Cut out a circle (it will serve as a membrane) on the inside diameter of the brake. Make a hole in the middle of the circle, after which stick to it on both sides of the puck. The threaded pin must be inserted into the washer, then tighten with the nuts.
