Thanks & Regards,

1. All modern cars and trucks have parking brakes that are referred to as emergency brakes. Two wheeled vehicles do not.
2. Yes they can also fail but usually this is a rare occurrence.
3. The parking brakes can always be applied by the driver by engaging the handle or depressing the foot pedal for these brakes.  The problem is that they will only engage the rear brakes and tend to make the vehicle unstable. But if the regular brakes go out the "emergency brakes" can be used because they are activated by a cable.

I can answer questions about traffic collisions with vehicles, motorcycles, pedistrians, bicycles, and commercial vehicles. Especially cases of low speed collisions and injury potential. I can answer questions about the vehicle code (specific for Ca and in general for other states) but I am not a driving instructor nor a vehicle mechanic. You need to talk to someone else about these issues.
