Probably not something to do if you've never done it before

the hardest parts are getting the brakes adjusted properly once back together, and tightening the hub nut, dont want to over tighten because of the wheel bearing, so find out how to do these first.

and remember which bits go where when removing, another tricky bit is getting the securing clips back on the pins that hold the shoes in place.

Could also upgrade to S2 stuff on the rear if your wanting some more stopping power!

Oh, and check behind the dust seals on the rear cylinders for leaks
