The Cardone Remanufactured Master Cylinder was a disastrous purchase that would have put my safety at risk if I hadnt replaced it immediately. According to my experience the cylinder was poorly manufactured and had multiple defects that caused the brake system to malfunction. The pros were none as the product was extremely unreliable and posed a serious threat to anyone driving with it in their vehicle. The only con is the severe consequences that could arise if this product were to fail while driving. Stay away from this product and protect yourself and others on the road..
