The rear brake pads on your 1993 Ford Escort can be changed by removing the brake pad Springs and break caliper. The brake pads will come off. Reverse the process to install the new brake pads.
There is a video on how to do this at www.teach-me-auto.com.

I believe the four cylinder has rear drums and the six has disc brakes.
Rear disc brake pads, no. Rear brake shoes, yes.
To replace the rear brake pads on a 1992 Toyota Camry, first lift the vehicle with a jack and remove the rear tires and wheels. Then, remove the caliper with a socket wrench and remove the old brake pads from the caliper. Remember to place the new pads onto the caliper with the indicator plate pointing in the direction that the tire turns. Replace the caliper and tighten the caliper piston clockwise before you put the tires back on the vehicle.
It depends on model and year of production. If you have front and rear disk brakes, you need 8 pads (4 front and 4 rear): 2 per each wheel. If you have only front disk brakes and rear drum brakes. You will need 4 front pads and 4 rear brake shoes.
I believe you need 17 mm box wrench for that.
the emergency brake pads ARE the REAR brake pads.
No, rear brake pads do not typically wear faster than front brake pads. The front brake pads usually wear out faster because they handle a larger portion of the braking force.
