Remove Boostrap Caret (arrow) on menu toggle links

My client wants me to remove the arrows on the top level drop-down menu items.

Is this somewhere in the functions file? I’m not seeing the code I need to modify.

Thank you, in advance, for your help.

.navbar .nav li.dropdown>a:focus .caret, .navbar .nav li.dropdown>a:hover .caret, .navbar .nav li.dropdown .caret {
	border-top-color: transparent;
