Not sure if this posted Limit tags to show on tags in category

Sorry, I am not sure if this posted the first time. Is there a way to limit the tags that show up within a category. For example, if I am doing a site on Auto repair and I am in the category of "Brakes" is there a way to limit the tags that only pertain to that category like "Brake Pads", "Replacing Brake Pads", "Brake Rotors"etc...? My tag cloud is getting way to big. Thank You in advance.
