Brake Shoe Lining Materials

[Chris KC]

...but that there doesn't seem to be independent testing or review material i.e. someone setting up their own comparison. It would be great to do that sort of thing for different sorts of cars and drums to save buying three sets and trying oneself.

So, lets get this right. What you're after is 'someone' to carry out an independent test of brake materials. Off the top of my head that's standard 1" and  standard 1.25",  with soft grey material, hard grey material, soft woven material, hard woven material, green gripper, kevlar base and anything else anybody can come up with. Repeat for semi Girling, full Girling, hydraulic with early drums, hydraulic with semi Girling drums, hydraulic with full Girling drums, coupled brakes, uncoupled brakes, fully compensated brakes etc. etc etc. Perhaps when that's been done another 'someone' could do the same to decide what oil to use.

Sorry mate, these are Austin Sevens, not Formula 1 cars.

Surely not necessary Steve. A back-to-back test with a single representative set-up would enable simple comparisons.
It would however need to eliminate the influence of application geometry (i.e. use hydraulics) and the materials would require adequate bedding; enough to make it quite a challenge for most of us.
