How tight should rotor bolts be?
How tight should rotor bolts be?
Like most other fasteners used on your bike, rotor bolts have a recommended torque. SRAM/Avid states that its rotors should be tightened to 6.2nm (55 in lb), while Shimano recommends 2-4nm (18 – 35 in lb) for its rotors.
Why are my brake rotors not coming off?
I have a 2002 Ford Focus which has had a speed-related vibration when I put on the brakes. I figured the front rotors are warped so I bought 2 new rotors and proceeded replace the old ones. I removed the brake calipers and all went well – except I can’t get the old rotor off!!!
What causes a bolt to loosen when it rotates?
Spontaneous loosening, or rotational self-loosening, is essentially when a bolt rotates loose due to shock, vibration or dynamic loads. Even a slight rotation can be enough for a bolted joint to lose all its preload. This is the most common cause of bolt loosening.
Why are my rotors rusted to the hub?
The rotors were similarly rusted to the hub. I believe that the clearance between the hub and the inner cavity that it fits in is so close that rust essentially welds the rotor to the hub. At first, I tried penetrating oil and a little rapping with a hammer around the hub area. No love.
Can a park tool be used to remove a rotor?
After all the bolts are safely out, remove the rotor. If the rotor came with new bolts, check them for an aerobic threadlocker. If the bolts have no threadlocker, you can use thread prep such as Park Tool TLR-1 inside the hub rotor mounting holes.

Why does a brake caliper take so long to swing out?
The reason it took a while for the caliper to swing out is that there was still a lot of clamping force applied by the bolt that was there. Took a few thousand miles of vibration and whatnot for it to loosen up a bit and allow the bracket to move. edit: I’d try and get free front rotors and pads out of it.
