We purchased a remanufactured power booster from this company for our high-performance automotive project, and we were impressed with the results! Based on our own experience, we found that this brake system component noticeably improved braking performance and overall feel. The booster was also easy to install and came at a reasonable price... The only downside we encountered was the lack of clear installation instructions, but anyone with even a basic understanding of automotive brake systems should be able to figure it out. Overall we highly recommend this product!
