Hey fellas,

Fazer failed its mot on the rear brake fluctuation. Assumed warped disc (could feel it in the pedal) went to replace and found this (after have to drill out 2 of the bolts)

The other half of that bolt was not in there, so someone had reused a snapped bolt and I could see marks all over it where someone had tried and failed to remove it.

After cleaning all the threads and going to put the new disc on I noticed this

The one where the snapped allen came out of is cross threaded... Im assuming this is cause of the brake fluctuation (?)

What are my options for repairing this? Tap and recut the thread, helicoil? grind/file the bolt shoulder so it clamps down flush? New rim?

Cheers.

Drill it. Tap it. Helicoil it.

Or buy another complete rear wheel.

I'd try a helicoil in the knowledge that if it doesn't work well, you can get a used wheel for around £100.

it would be great to get that wheel in a lathe to check the shoulders are level and square too. Or at least put a dial guage onto it after fitting the helicoil and disc.

Yep deffo going to a machine shop, beyond my level.

That was my main concern with a helicoil though, would that be considered a safe repair? I would assume it would be strong enough for the forces it would have to deal with but wanted to make sure.

If anyone has any machine shop recommendations in the midlands/derbyshire im all ears.

Fit all the other bolts correctly, glue the half bolt on to the disk so it looks like you have them all present and correct, mark it with tipex.

don't do that..

Probably cheaper buying a whole wheel/ sprocket/ disc/ tyre than getting someone to work on it.

Not easy to pull a thread round like that on a rear disc. I reckon that someone in the past has ridden off with a disc lock fitted and bent the disc along with the bolt, stretching the hole sideways.

I'd run a tap down it first with a guide to keep it straight. If that didn't work then probably a 2D helicoil.

Cheers for the help fellas

2x Helicoils later and shes back up and running. Turns out someone previously tried to drill out the bolts, drilled offcenter and left some of the old bolt in there. That was the cause of the bolt going in at a angle.

£60 for the repair and made a very useful contact.

two holes knackered then?

I have a GPZ900 wheel with immovable disc bolts like those. Even withstands air impact gun. It was only for going on ebay after I robbed the new 16" tyre of it for my FZ, so I abandoned it..

Are these bolts going on 'dry' and then corrode or are they loctited?
