The review posted from the reviewer is not true. The customer brought a vehicle in for a repair that he himself tried to repair three times before we received the vehicle. The problem was not with the master cylinder that he had already purchased before...but...after a very long drive of over 15 miles to exhaust pipe that he cut off the truck was blowing hot exhaust on the brake line causing the brake fluid to overheat. And to top of the repair of the truck that we repaired the customer took the vehicle without payment and has NEVER paid for any repairs. So in the end he stole the repaired vehicle!
