linear actuators (i think)
any idea where i might find something like this?
 
Description
it would need to pull down when no electric is applied, and realese or extend when 12v is applied.
i'm sure there is something out there to do this.
if it can fit into the handbrake able bit of a sierra caliper then it would make a good electric handbrake, but it would need to pull in when no
electric is applied to make it work
anyone seen anything?

Think about the kind of forces you would need to apply, with no current present. This would need an enormous spring, and this arrangement would mean
any fault condition would apply the handbrake on full, not great if you happen to be on a motorway at the time.
If you must use a electric handbrake (poxy things IMO) then I'd suggest you use an OEM actuator and cables, but I'd certainly recommend
you go for a traditional manual handbrake.

Most oem systems use a worm gear so that when the cables are wound in nothing can unwind them

don't busses have pneumatic systems that use air to hold the brakes off?
i probably will go with normal cables, but thats far from ideal too. this chassis wasn't designed for handbrakes lol

probably in a door lock mechanism, drivers door as the others are only actuators. I am sure that this system is present on central locking systems

the actuaution force required for a handbrake and for a door lock are far from simliar
i'd look at a proper linear actuator using a screw, but it will need power to activate and deactivate.

Don't know if it would work but how about a servo off a starter motor
Bus brakes have about 80psi air to make them work

Thats an interesting idea Blake. Would suit my car perfectly too!
How long can i resist the temptation to drop a V8 in?
