brake system of car controller was not working

[Ash-creater21]

it may be due to wheel collider didn't released the brake I searched it Quit a while I got the script that was

private void HandleMotor()
{
RearLeftWheelCollider.motorTorque = VerticalInput * motorForce ;
RearRightWheelCollider.motorTorque = VerticalInput * motorForce ;

    currentBreakForce = isbreaking ? breakForce : 0f ; 

    if(isbreaking)
    {
        
        applyBrake(); 
    }
    else
    {
        currentBreakForce = 0f ;
        releseBrake() ;  
    }
  
}
private void releseBrake() {
    FrontLeftWheelCollider.brakeTorque = 0f ; 
    FrontRightWheelCollider.brakeTorque = 0f ; 
   RearLeftWheelCollider.brakeTorque = 0f ; 
   RearRightWheelCollider.brakeTorque =  0f ; 
}
