 Lubricate parking brake cables, yes or no?
Hi;

I'm installing new front and rear parking brake cables on my '78 Trans
Am. Front and one of the rear are OEM with stainless steel cable,
while the other rear cable is aftermarket with a black, nylon-like
coating.

I have looked through my Pontiac service manual a few times, but have
never found any reference to lubricating parking brake cables.
(Neither have I found any reference that says *don't* lube the
cables!)

I know from bitter experience that, once a cable starts to seize up,
lubrication may free it for a short time but is not any kind of
permanent fix. Also, the back cables on this car are at least fourteen
years old (which is how long I've had the car), and this is the first
I've had to deal with them. (One snapped in January, and it looks
like the other is at least semi-seized.) So the cables may work
better unlubricated (less gunk attracted to the lube to get sucked
into the cable housing), and last just as long as lubricated ones?

Trying a quick google does not give any really authoritative results.
I wonder if some of the experienced mechanics in this group have any
advice?

Thanks!

There are no front parking brake cables. Parking brake is attached to
the rear only. No need to lubricate those cables. You should be
fine for another 30 years with a new set.

How long has this been true? I remember in the 1980s a
parking brake cable jamming for (I was told) lack of lubrication.

Depending on where you live, it may never have been true. If you live
somewhere that uses lots of road salt, I'd lube the e-brake cables every
couple of years.

Forever in my part of the world... As Nate said it may be different
in areas with lots of road salt though it seems to my salt free mind
that the grease would just trap the salt making the problem worse.

More of a problem than salt corrosion in areas with bad winters is
that the slush builds up around cables and bellcranks and freezes.
Many of us in these northern climes were taught to use emergency/
parking brake strictly as an emergency brake, never for parking,
unless you are willing to get under car with pliers or wrench and
return brakes to off condition.

Actually, there IS a "front" brake cable on most cars.

There is usually a single cable that comes from the activating mechanism
inside the car - this is known as the "front" brake cable.

There is usually a split where the "front" brake cable attaches to the two
cables that go off to the two rear wheels - these are known as the "rear"
brake cables.

On cars like the Subaru which applies the parking brake to the front
wheels, nomenclature is likely different, but the principle is the same.

Funny how you can read something and completely miss the point. I've
never heard it referred to as a front brake cable before but now that
you explain it makes perfect sense... Can't say I've ever had the
need to replace one either so never really thought about what you
would call it.. Guess that was my short bus moment for the week.

I usually lube them with a good dose of dry lubricant. Solvent carried
graphite seems to work real well. I also like to install rubber boots on
the ends of any open style cables. I get the boots from a local boat
shop. They are used on rudder cables and such to keep water out of the
cable.

In NY at least the salt and crappy winter eat cables for lunch. It is
almost the top cause for failures during inspection.

Your idea to use a marine cable boot is the best I've seen in a while!
Thanks for sharing it.

In the past, I've used a motorcycle cable oiling kit with excellent results.
A thin base solvent carried a teflon added grease the length of the cable,
giving it thorough lubrication and water resistance. Adding the rubber boot
as you describe would make it the best job ever.
