I obviously bought this to save money. I've worked with cars all my life. The spacers were too small and the anthers too big. I've been trying to put everything together for about an hour and barely made it. I put it back on my truck and started bleeding the brakes and at about 5 o'clock pressed the brake pedal and one of the seals blew. So basically I threw away $16 to save money, good times. Simply purchase a remanufactured caliper from your local store and save yourself money, time and frustration.
