Content Types updates not getting pushed to Lists/Libraries Sharepoint 2013

Question

Hello,
We have updated Content Type at Content Type Hub(ex. Making columns Hidden/Req...etc..). These changes are pushed to the consumer sites site level Content types but the problem is these changes are not reflecting at List/Library level Content type.
Is there a way to explicitly push down the changes ?

perform the changes to the ContentType make sure to push changes to the lists while updating the ContentType.
For now, you might need to perform some clean-up job here, just to make sure the field is deleted from all the lists, with your Custom ContentType. Use the following PowerShell script for clean-up! Vårsegod :)
Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
$site = Get-SPSite "http://your.site.com"
foreach($web in $site.AllWebs)
#iterates through all the Lists
for ($i = 0; $i -lt $web.Lists.Count; $i++)
$list = $web.Lists[$i];
$MyListContentTypes = $list.ContentTypes
if ($MyListContentTypes -ne $null)
$ct = $list.ContentTypes["You Desired Content Type Name"]
if($ct)
Write-Host "In list Content Type and deleting the field" $ct.Fields["You Field Name"].Id;
$ct.FieldLinks.Delete($ct.Fields["You Field Name"].Id)
$ct.Update()
Edit: How to push down changes to all the Content types via SharePoint Server Object Model:
using (SPWeb oWebsite = new SPSite("http://MyServer/sites/MySiteCollection/MyWebSite").OpenWeb())
SPList oList = oWebsite.GetList("MyWebSite/Lists/MyList");
SPFieldCollection collFields = oWebsite.Fields;
string strNewColumn = collFields.Add("MyNewColumn", SPFieldType.Text, false);
SPFieldLink oFieldLink = new SPFieldLink(fields[strNewColumn]);
SPContentType oContentType = oList.ContentTypes["Specification"];
oContentType.FieldLinks.Add(oFieldLink);
oContentType.Update(true);
Edit 2: Update a Content Type using PowerShell:
Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
//get the specific Root web
$spweb= Get-SPWeb "http://your.site.com"
//get the fields collection
$fields = $spWeb.Fields
//get the specific field
$field = $fields.GetFieldByInternalName("Name of you field")
//get the specific Content Types from Root Web
$contentType = $spWeb.ContentTypes["You Content Type"]
//delete a field from a Content Type
$contentType.FieldLinks.Delete($field)
//add a field to a Content Type
$contentType.FieldLinks.Add($field)
//update the Content Type and push changes to the children
$contentType.Update($true)http://sharepoint.stackexchange.com/questions/42744/how-to-add-a-field-to-a-contenttype-with-feature-upgrade-for-new-and-existing-shttp://msdn.microsoft.com/en-us/library/office/aa543504%28v=office.14%29.aspx
