Brake MC pushrod

I did like TrailBeast said. Since then, I read it is easier to pop it out in the car, using the brake pedal leverage, just remove the brake light switch first. The rod locks in place with a square rubber bushing. It slides in easy, but won't come out without tearing the rubber since a step locks it. Old bushings can be hard and appear to be plastic (were probably rubber). This assumes your new MC is for manual brakes. Power MC pistons don't have the locking step. Most manual MC's I have seen come with the brake rod and dust cover/retainer. I don't know where to buy just the rubber bushing. When I bought a 4 to 2 bolt adapter plate recently (ebay), it came with the bushing.
