How I can stop trail render emiting?

I have an array of trailrenders and I have a script whitch when the handbrake toggle is on , trailrenders need to start emitting and when the hand brake toggle is off to stop emitting but dosen t work. I tried to call the function in handbrake script but nothing. Here is the script using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class CarParticlesControl : MonoBehaviour { public CarController Car; public ParticleSystem[] WheelsSmoke; public TrailRenderer[] SkidMask; public Toggle Handbrake;

     private void Start()
     {
         Handbrake = GameObject.FindWithTag("HandBrake").GetComponent<Toggle>();
         foreach (TrailRenderer T in SkidMask)
         {
             T.emitting = false;
         }
     }
     public void StartSmoke()
     {
         if ( Handbrake.isOn)
         {
             foreach (TrailRenderer T in SkidMask)
             {
                 T.emitting = true;
             }
         }
         else
         {
             foreach (TrailRenderer T in SkidMask)
             {
                 T.emitting = false;
             }
         }
     }
 
     
 }
