Are all drums equal? Likewise shoes..?
I need good quality Sierra drums and shoes. Any recommendations?

Drums from Brake Engineering and Ferodo Premier shoes, if you want standard friction material.

I'm sure I've seen grooved drums before, possibly for VWs. Might be worth investigating.
Other than that I'd have thought new OEM drums and pads from Ford would be the best bet. Plus (as I'm certain you would anyway) making
sure the rest of the system is in "as new" working order.

For mini's you can get aluminium drums with cooling fins. There is a steel ring in them for the friction material to work on. Don't know
if such a thing exists for sierra drums.
For braking effort regular OEM parts will be fine.

Assuming you have 9" drums just fitted a new set of Sierra drums and decent quality standard shoes --- ie Ferrodo/Mintex
Although finned drums are stiffer and offer better cooling you aren't going to find finned drums for a Sierra in any case if brake temperature
were a problem it would be lot easier and more cost effect to convert to discs.
Grooved drums ----- good expensive joke on whoever is daft enough to buy them.
Problems with drum brakes
(1) As the temperature rises the drum expands more than the shoes, result "long pedal".
(2) They have a lot less cooling area than discs.
(3) Mechanical deformation of drum and shoe when high pedal pressures are applied, this gives a spongey long pedal and limits the stopping power of
the brake ie friction coefficient drops off at higher pedal pressures. .
Advantages of drum brakes.
(1) Great handbrake.
(2) Brake self servos particularly at low pedal pressures.
(3) Brakes shoes last twice as long as brake pads.

Cheers all - I don't expect drums to be an issue, even doing what I'm doing with them...
