What size is the rotor bolt?
Everyone knows that rotors are sometimes hard to remove if they are rusted onto the hub. So there are two threaded holes, and you can grab the right bolts from somewhere else, and thread them into those holes to pop off the rotor. The correct size is M8 x 1.25.
Do you need the screw that holds rotor on?
But, no matter what car I work on, Set Screws on brake discs are a constant pain. Set screws are put on during manufacture to keep the disc in place on the assembly line. However, once the car rolls off the line, they are completely useless. Just to be clear, the set screw is on the brake disc to hold it in place.

SRAM’s HS1 disc brake rotors are available in five diameters: 140,160,170,180, and 200mm. Shimano, and most other brake companies, offers rotors in four sizes, which can still be a lot to choose from. They do a better job of displacing heat generated from braking, and can provide better modulation.
What is M8 screw?
So an M8 bolt would have a shaft diameter that’s slightly under 8mm which means that the bolt should fit through an 8mm hole.
What are rotor screws used for?
Edit: From what I have read online they are mainly used to hold the brake rotor in place on the assembly line while manufacturing the vehicle. So they may not be really necessary after all. A lot of people seem to leave them off without any ill effects.
What holds a rotor on?
There is a hex screw that holds it in place to keep it from spinning when mounting the wheels, but that’s it. When you torque down the wheel studs it sandwiches the rotor between the wheel and the hub.
How do you get screws out easily?
If the screw is being especially stubborn, try using a hammer. With one hand, hold your screwdriver in place and slowly try to turn it while hitting the back of the screwdriver with a hammer. This is the same premise that an impact driver works on.

How big of a bolt can be used to remove brake drums?
Size is 8mm X 1.25. Mine still stuck because brake pads were expanded try turning the star wheel adjustor as well. Later found out the problem was the ridge of rust that built up on the wheel. As long as the wheel turns the brakes pads are not too expanded to pull off the drum. Just had to let it soak overnight with rust remover.
Can a wrench be used to loosen a brake rotor?
Next up, you’ll want to find a wrench, probably around 12mm, to slide onto the wheel lugs and jamb against the brake caliper. This will prevent the rotor from spinning when you are trying to loosen the bolt. The next step can actually be done before you have the wrench on there, but I did it out of order for some crazy reason.
Are there Phillips head screws on brake rotors?
If you are lucky though, you have a car that doesn’t have the stupid phillips head screws holding the rotors on to the hubs. I was unfortunately not so lucky recently, but I have destroyed enough of these little screws to eventually figure out a way to get them out.
