I actually like that the metal bushings don't fit because then they don't get stuck/rusty lol. Maybe even my "Raybestos" sockets. They still keep the brake dust off the lubricated pins very easily. Yes, you need to fill the inside of the rubber bushing with grease. Lubricate the pen, insert and pull out from this hole of the bracket several times, do not spare it, but also do not get anywhere. My Camry 05 brake fingers had no hope of unlocking even with a flashlight. It was easy to replace and fix. A+
