i was wondering how to adjust the breaks on my 2000 hyundai accent because
the breaks work just not the emergency break

 

The shoes have the typical star wheel adjusters. Take the rear drums off
and adjust the clearance until the shoes create a small amount of
resistance on the drum when turned.

If you still need to adjust your parking brake after adjusting the shoes,
there's a parking brake cable adjustment under the rear console. You can
turn the cable the rest of the way until adjusted properly. Remember,
you should be able to turn the rear wheels, but a small amount of
resistance is okay.
