Heres a couple pics of me fixing my blazer's emergency brake yesterday. A stupid little clasp at the top of the ebrake held in with a phillips head screw (just underneath the top of the brake shoe) was bent back and the brake shoe was not flush against the back plate. It caused all kinds of popping, clicking sounds and vibration while I was driving. So to fix it I pushed the e-brake shoe flush against the back plate and pushed the metal piece back into place and tightened it up. While I was at it, I used a small wire brush and srubbed of a bunch rust build up to make sure the ebrake would work smoother. I then followed it up with a quick clean up job with some brakekleen and an easy reassembly. Simple easy fix that just saved me $80 in labor from a mechanic.
These pics show the brakes and rotor off revealing the ebrake shoe:
