The first one is Ford Pilot. Or at least the same as on a Pilot. It looks like the front pilot brakes I have seen, with the transfer levers and pushrods to make it like a twin leading shoe setup. BUT! I only thought that setup was used on the front. That does look like it is on a rear axle casing.
Front Pilot brakes are operated by a cylinder that bolts on the back of the front backplate. Rears are operated directly by a cable (I think, either a cable or rod - not hydraulic).
Not sure on the second one, except that it is a mechanical pushrod type, meaning it was used on the front. The third looks like a rear mechanical type.
Mart.
