This product is simply not trustworthy... I purchased it hoping to improve my automotive system but it let me down. Through trial and error, I found that this hardware just doesnt hold up. It's frustrating to have to keep testing and retesting to ensure my brake is properly secured. The only pro I can think of is that the price is lower compared to other brake systems. however, the cons outweigh the savings. I would not recommend this product for its unreliable performance..
