HI: I do not normally review products. However, for Brakecrafters (BC) and Lindsey I am gladly doing so. I called BC as I was desperate for parts to make it to Daytona for Bike Week. Changing out my pads led to me finding that half my caliper pistons had seized. The stock parts are steel and I nobody had them in stock anyway so that was not a solution. Her comes Lindsey to save the day! I called and Lindsey promised to get kits for all my calipers out that day and made sure they got to UPS for my Next Day Air shipment. Then she sent an email confirming that it was all completed! AND these kits are BEAUTIFULLY DONE! 316L pistons, oil fittings, all the O-rings, little reusable grease cups..AWESOME. Being an engineer and weekend mechanic, I appreciate nice stuff and these are the BEST! If you want to see how the USA should do Customer Service and Manufacturing, visit BC or give Lindsey a call. As long as I ride, I will ride only on Breakcrafters KITS! Thank you so much, Ed
