There are no emergency brakes on the front wheels of vehicles.
your rear brakes are your emergency brakes. if your handle is coming up to much you need new brakes most likely or sometimes just an adjustment.
Only on air brake vehicles.
No. The emergency brake uses the same brakes. It'll be equally ineffective.
The brakes may make a clicking noise if the caliper is going bad. I just changed the brakes and the rotors and discovered my car was making a clicking noise. The garage I took it to replaced the caliper, so now it doesn't make the noise anymore.
The emergency brakes work by way of a cable system. If the brakes are not holding, the cable may be able to be adjusted, or the pads could be worn too far for the brakes to hold.
maybe
use your emergency brake if in motion, if not in motion get new brakes!
Check your brakes(pads and rotors)
