Re: E-Brake sticking
Hi Phil;
The stronger return springs may help if the problem is caused by the
e-brake arm on the caliper sticking, but I don't think they will help very
much if the cables are sticking. They may have to exert as much force as
your arm can on the e-brake lever, and you can't get a spring that strong!
I think the stronger return springs may improve the overall operation of
the e-brake system and extend the time between service, but the downside may
be that when the brakes start to stick with the stronger springs, the
e-brake arm shafts are even more corroded.
IME when the cables start to stick, they are finished - they cannot be
repaired. On my last replacement I filled the cable boots with silicone
grease to try to keep the moisture (and road salt) out and extend cable
life.
