I recently change the all brake system for prostop break parts, so I would like to know how good are they, and the are made on USA, because i know the american parts are better than taiwan or chinese for the american truck

any idea it's welcome thank you

 

Did you already put the parts on your truck? It sounds like you have, so I would say just test them out and see how you like them, there have been threads on here asking about them and the responses to those threads said they were quite a bit better than factory.
