2003 kx 250 rear brake problem

<< < (2/4) > >>

Foxx4Beaver:
eh, you can find used swing-arms on e-bay....only problem, '03 was an "only year" as far as the swing-arm, so it could take a while to find one.
I've also heard of guys cutting off the old "key" on the swing-arm, and having a newer/better key welded on in it's place.

Johnnycrash:
The rear axle nut was loose and the hole for the cotter pin is outside the grooves on the castle nut.

yeah...if it was ridden like that for a while, that could do it.

Johnnycrash:
I think I need to shim out the swing arm to where the castle nut works. Everything thing is outta wack for the brake with it squeezed in so tight. Looks like I can fit a washer between the caliber bracket and bearing retainer. Worth a shot!
