Well, the first observation is that the new pads when fully located still overhang the outer edge. The inner edge is bang up agaist the inner edge of the disc, so skimming a bit off each angled corner of the backplate, to 'edge it' down won't really work, although I did consider it.
I've had Greenstuff discs & pads on the Roadster for six years, they were fitted when I got it, and have been no trouble. Maybe I don't brake hard enough. smirk2

Anyway back to the story:

Here's a closer photo of the reamer. The silver tube on the right is the pilot with a sliding adjustable collar, which to be honest is not much use with Morgan stubs due to the length, but the pilot is essential to keep it straight. As the cutting blades adjust right to left they ride up a taper so cut a larger diameter hole, They are retained at each end by a taper threaded collar. Black on the left, silver on the right.



This show the model number - there are loads to chose from.



Reamer adjusted, job done, and cleaned out - I'm getting faster each time I do this.



Here's the nearside on the way up. I slot a screwdriver in the base just in case the rebound spring makes a bid for freedom, but it seems quite stable and once it gets inside the lower tube bracket it can't go far. (Picture will rotate tomorrow).



Almost back together:



Pads and lube - it's just like Coppaslip.



Not enough angle to see the overhang...........just visible as a pink band.





So all I have to do now is make up a set of deluxe gaiters as I fitted to the Roadster after the kingpin job, oh and then do a full service. Good job I'm part time retired, and that MrsW is tolerant. grin2
