'Sticky' right emergency brake on 2001 Honda Accord

I recently replaced the disc pads on the rear wheels of my 2001 Honda
Accord sedan. Thanks to the advice on this and other souces on the
interent, it went fairly smoothly and only took me about an hour and a
half. After I had everything put back together, I headed off on a
fairly long road trip, only to discover that the right, rear pads had
not released when I had let go the emergency brake. I was able to
reach in under the car (behind the wheel) and grab the 'actuator arm'
and pull it towards the back, thereby releasing the brake. Since then
I have not been able to use the e-brake because, whenever I give it
the 8 or 9 'clicks' on the handle, it won't release the arm on the
right, rear brake when I then let it go. It seems to work O.K. if I
only do 5 or 6 'clicks' but, unfortunately, then the e-brake doesn't
hold the car well enough. Any suggestions as to what might be causing
this problem and what I can do to remedy it?

 

Start by making sure the parking brake cable's clevis is free to swivel on
the actuator arm on the caliper. These tend to seize with rust. If that's
free, then...

Disconnect the parking brake cable from the caliper (clip and pin at
clevis). Now see if the cable will slide easily within its sheath. If it
does, you know that's not the problem. Then...

Cable still disconnected, try rotating the actuator arm on the top of the
caliper. Does it rotate freely and return /fully home/ against its pin each
time you release it? If not, then you have rust inside the caliper at the
parking brake mechanism and need to rebuild or replace the caliper.
(You may need to pull the caliper off its mount so as to be able to rotate
the actuator arm more easily.)
