Based on my experience the Carlson Quality caliper repair kit has made a noticeable improvement in my automotive brake system.The quality of the materials used in the kit has resulted in my brakes feeling more responsive and consistent. The kit was easy to install, saving me time and money at the repair shop. The only downside is that the price may be slightly higher compared to other repair kits on the market. Overall, I would highly recommend the Carlson Quality caliper repair kit for anyone looking to improve the performance of their brake system..
