New rear disc.

[Iain]

Is there much involved in replacing the rear brake disc? A trip to the dealer for me means a 2 day trip. I know how to get the rear wheel off so looking at it the disc comes next.

Hi Iain,
what sort of mileage do you have ~ to be looking at replacing your rear disc?
Are you below your minimum limit disc thickness?

I'm on 14000 miles. The dealer says the disc is scored and needs replacing just don't want to go back to him another time if it's a job I can do myself.

Its not a hard job at all, but if you are bothered by it take your new disc, your wheel to any indi bike shop and let them do it.
Once you have the wheel off it should take about 15 mins to do.
The big hard part of that job is getting the wheel off.

The rear disc is not attached to the wheel but to the final drive unit. 
To change the disc, the removal of the the wheel is required to get to the bolts holding the disc.
Use the rear brake to loosen these bolts. Remove the rear brake unit and pads after. Always use new pads with a new disc.

Thanks Mustang, thats what I get for not looking at the book or the bike before typing.
I still think the hard part is getting the wheel off of the bike. At least it always has been for me.

Does the new disk need to be turned/trued before installation?  I've never had to replace a moto disc yet.  When I was a teenager I worked in an auto parts store.  Every new disk sold had to be turned (as little as possible) because some warping is expected with storage.

That is not something I have had to do.
