Two years ago when doing my brakes I renewed the cables at the rear wheels
for the emergency brake. Recently when checking various things before taking
off to south of the border in March , I noticed that there is alot off
chaffing taking place on the outer wrapping of the cables where they go
through a large guide strap just by the front of the mid boggie wheel.
This is the cable that goes to the mid wheels brakes). I was very
surprised at how much wear there was in just under 10,000 miles. The
plastic cover was worn through and the outer metal casing was starting to
get worn as well. I recall that when I took off the old ones they wear badly
worn at this point. Once the outer casing gets cut through on one side, this
could at least to some degree affect operation of the cable and emergency
brakes. Although the strap is insulated, I believe the wear occurs due to
the constant up and down movement of the wheels causing the cable to rub on
the strap at exactly one spot all the time. For those who are not fussy or
if you don't use your hand brakes it most likely doesn't matter, however I
like to keep my mechanics all working well so I keep my brakes adjusted and
they all,including my emergency, work very well.
For a fix I cut a 3 - 4 inch piece of soft plastic tubing,spit it down the
centre,squezzed some rubber like cement into it and wrapped it around the
wear area. Goop ,silicone or any glue/filler that stays soft and malible
would do. Whether repositioning the strap would help further or not I'm not
sure ; I'll look at that one further . Some folks may want to check this
area.
