80-90% is fine.
: My parts arrived today. I am optimistic
: that the new brake components will
: improve the braking feel of this
: The new shoes match the drums pretty
: well. The shoes appear to contact the
: inside of the drums along 80% to 90% of
: their length. At the end that is not
: in contact the gap between the friction
: material and drum is less than
: 0.010". If I put sandpaper on the
: inside of the drum the contact area is
: going to decrease so I think I'll just
: try the shoes "as is" rather
: than improvising an arcing technique.
: Unfortunately, I can only do so much
: prep work at night after work.
: Installation and a test drive will have
: to wait for the weekend.
: I'll keep you posted.
