    Why is it when i lock up my rear wheel it vibrates and moves slowly?

    Wassup Guys,
    Currently i am riding a 2015 trance 2 and whenever i lock up the rear wheel it vibrates violently and the rotates a little whist doing this. I have tried tightening the axle, checking disc pads and also tightening the bolt on the outside of the cassette. But i still cant find what is causing this.
    The brakes dont seem contaminated as they brake just fine without locking up.
    Maybe it has something to do with the disc itself? I really dont know.

    Any help or advise would be awesome, Cheers

    Your rotor is probably causing vibration.
    It might be bent.
    Also, it's worth checking out the rotor bolts.

    Some combinations of rotors and calipers don't play well together. I found this by using XTR freeza rt99 rotors on my Guides. It would vibrate and make noise when braking hard.

    Switched to Formula rotors and it was gone.

    It wasn't the particular rotor either because I tried my friend's rotor and it was the same.

    I don't think it's spokes at all.
    Check caliper and rotor bolts, make sure both pistons on the caliper are working and check the rotor.

    It's easy to find out if it's rotor or not as it's easy to source and try another rotor.

    You could also have play in the rear hub bearings/axle. I'm not sure which type of bearings are in the rear wheel of your trance, but it's worth trying another rear wheel to make sure.

    The wheelset is not that high quality and if you ride a lot it's not unexpected if it developed play over time.
