what are brake discs made of?
are they just plain mild steel?
or a special grade, or alloy?
thinking of handbrakes again, forgot about the prop disc types. i've got sierra rear calipers on the back, but wonder if a prop mounted disc
might make the cabling easier

thanks BT. makes my idea of getting one machined to fit the prop a little more difficult it think.
will, good question... it should do, since if the car is trying to roll backwards or forwards, it should be trying to turn the prop anyway, but it
wouldn't work if the car was trying to spin round on the axles axis. how likely is that ever going to happen?

It should do as its only like leaving your car parked in gear.
Unless one wheel is in the air/no traction I think.

BMW often fitted stainless discs to their motorcycles, I know this, I've had one (or two). NOT the best friction disc material in the world,
doesn't have the bite of cast iron, but it doesn't rust either..... which is why I assume they fit them.
Aftermarket cast iron discs are a-plenty.

Pads have to be special grade for stainless steel.
Transmission brakes are something to avoid at all if possible.

Landrover have used a transmission mounted drum brake for the handbrake for years, mabye as long as they've been in production!
The biggest problem is both wheels must have grip for it to hold, if either can spin then it could move. A LSD would help a lot dependant on
it's operation.

you can use stainless for a transmision brake as it should only be used to keep the car statinary as opposed to stoping it (unless in an emergency),
rally design used to do a mechanical calliper that was ideal for this...
just because you are a character, doesnt mean you have character....
for all your bespoke parts, ali welding, waterjet, laser, folding, turning, milling, composite work, spraying, anodising and cad drawing....
