Why do fixies (fixed-gear bicycles) have one brake on the front?

Why do fixies (fixed-gear bicycles) have one brake on the front?

It feels safer because it is safer. With a fixie you can brake the rear wheel from the pedals. In theory, you only need a front brake. The theory is great for experienced fixie riders. For novice ...

Can an out of alignment brake caliper lead to the piston falling out?

No, no way the pistons can come out if the wheel is mounted, no matter how worn the pads are and how out of alignment the calipers are. Misaligned pads cause extra pad wear and poor performance until ...
