Has anyone else had this problem (400ex)

[DEAL]

Has anyone else besides me had/have problems with the hub that holds the rear disc (rotor) onto the axle cracking.
Mine cracked in 3 places.

it is a common problem ....ive seen many of them cracked...myself included. they run about $80 new i think

If I remember correctly the 300ex hub isn't alunimum. Which probably means its a bit stronger.
Its the same disc (I think) and the splines on the axle should be the same , Do you think it would work?

[Pappy]

i dont think it will but maybe worth a shot. i have aused one if ya need it

do you run a skidplate??

MX and no skids are common reasons for cracked rotor hubs. But who needs brakes anyway...:ermm:

I don't run a skid. But I don't run any trails that have rocks large enough to gear new the rotor.
Its a little bit of bolth causing my problem I think.

well just your rotor digging in the dirt is not a good thing. The grond is not as hard as rocks but your still askin for a problem.. Breaking a chain is really gonna suck for ya in the middle of nowhere...:(


No skid is for a MX track and dunes only. All other riding requires a skid of some sort..evena stocker....:cool:

I'm ordering a skid next week no worries.

I run a belly skid and have taken some fair sized chunks out of it from landings.
I had a swingarm skid I used to run but it got chewed up.
