I am in the process of restoring my rear brakes. New calipers, new rotors. The rotors and calipers are shot and new ones are on the way. I'm trying to get the old rotors off and I've discovered a rotor attachment screw (one of two) on each rotor is stripped.
One of these on each rotor and the inside pad adjustment screw is stripped on both calipers. Since I am ditching the rotors, can I just bore out the head of the screw, take the rotor off and then either wrench the screw out by the exposed shaft of the screw or, if all else fails, tap it out? I'm probably forgetting something but it seems like a plan... Advice? B T Rex |

Drill the head off the screw to remove rotor, then remove the screw with some vice grips, if they don't just screw out by hand.

B T Rex Yes, that method works fine but before you try to remove from the hub, heat the remains of the screw, red hot and while it's cooling, touch an old wax candle or use some penetrating oil. the heat will help to break the bond and the oil or wax will help it unscrew. |

Thanks Guys! I went right after them and got them in short order. Now I have to replace them. They seem like they're brass?

I did not think it matters much. They just hold the rotor in place. Some anti seize might make it easier next time around.

The screws only hold the rotors to the hubs until the wheels are bolted on, then the bolts do all of the work and the screws are useless... Rumor has it that they were primarily there to keep the rotors from falling off on the assembly line.
