Car wheels not stopping when I brake

Im creating a kart game and when I stop the kart the wheel dont stop and the kart takes a very long time to stop and reverse

I have a wheel colider on each wheel

 public class Car : MonoBehaviour
 {
     public float maxTorque = 5000f;
     public float speed = 5000f;
 
 
     public Transform centerofMass;
 
     public WheelCollider[] wheelColliders = new WheelCollider[4];
     public Transform[] tireMeshes = new Transform[4];
 
     private Rigidbody m_rigidBody;
 
     void Start()
     {
         m_rigidBody = GetComponent<Rigidbody>();
         m_rigidBody.centerOfMass = centerofMass.localPosition;
     }
 
     void Update()
     {
         UpdateMeshesPositions();
     }
 
     void FixedUpdate()
     {
         float steer = Input.GetAxis ("Horizontal");
         float accelrate = Input.GetAxis ("Vertical");
 
         float finalAngle = steer * 45f;
         wheelColliders [0].steerAngle = finalAngle;
         wheelColliders [1].steerAngle = finalAngle;
 
         for (int i = 0; i < 4; i++)
         {
             wheelColliders[i].motorTorque = accelrate * speed * maxTorque;        }
     }
 
     void UpdateMeshesPositions()
     {
         for(int i = 0; i < 4; i++)
         {
             Quaternion quat;
             Vector3 pos;
             wheelColliders[i].GetWorldPose(out pos, out quat);
 
             tireMeshes[i].position = pos;
             tireMeshes[i].rotation = quat;
         }
     }
 }
