Hi.

I just had a problem with my Dewalt chop saw (DW705). At first, I
noticed the brake was not catching all the time when I released the
switch. Then, a little while later the saw just quit working. So, I
pulled out the brushes and cleaned them up (I have been doing alot of
MDF cutting) and then the saw started working again. After a little
while, it stopped working again. So, off I went to get two new
brushes. Installed them and the saw is back up and running great. But
now, there is no electric brake at all. I am wondering if I installed
the brushes wrong or if something else needs to be replaced.

Can anyone explain how these brakes work, and what would cause it to
stop working?

thanks in advance.
