Comstar brake shoes
McCabe-Thiele (Ted):
As Byan has said with age & corrosion the bond between the backing & the friction material eventually breaks both on Pads & Brake Shoes even on good quality brands.
Back in the 1960's most brake shoes were rivited on - you could buy linings and rivet them on yourself quite easily.
Laverda Dave:
I always renew brake shoes now when restoring a bike simply because you don't know when the shoes were last changed. Ratty's rear shoes are marked as Honda and show wear so as far as I know they could be the 1976 originals. Having a rear wheel lock up at speed due to de-bonding isn't a nice thought.
McCabe-Thiele (Ted):
I've never experienced de-bonding on brake shoes only twice in a lifetime on disc pads.
I was driving a Mini Mayfair Auto within a couple of weeks of ownership - it was due to serious corrosion on the front hubs as the vehicle had been little used for a couple of years by PO.
The pad friction material came off completely - with frantic pumping of the brake pedal at a roundabout the brakes worked again with metal on metal contact on one caliper - boy did it squeal and pull to one side!

These have been in there since at least 1998 when my Dad bought it as a box of bits. He rebuilt it and rode it once around 2000 but it still needed work that he never got around to. Not surprising that they have perished. Now I’m working through getting it back on the road. They were on the list to check.
Bryanj:
Remeber when Mike Brewer did an Isetta, the linings fell off that on the way to workshop, i have had half a pad lining fall off on my L200 at 110,00 with about 5mm material left and have had old stock fall apart
