Perhaps an idea is to use the parking brake less for parking:
let the car remain in gear (1 or reverse).

Cheers,

Hans

Having had a number of BL cars over the years they all tend to suffer from
the same problem, and I have found the only solution is to dismantle the
linkage at the drum at every service, clean and lubricate - and that
includes a thin smear of grease on every metal-to-metal contact.  I have had
less problem with the handbrake end of the cable and the pivot on the axle,
possibly because they get less wet and dirt than the wheels, but they should
be free and lubricated as well.

Pull up the handbrake and see what angle the lever makes with the cable as
the shoes contact the drum.  Ideally they should be at right-angles for
maximum effectiveness, old levers will wear where the shoes ride on them and
need pulling out much more.  Mine have been built up with weld to restore
the amount of lift.  I can lock the wheels easily when rolling the roadster
down the drive and leaning in and pulling up the brake, the GT is not quite
so effective, possibly because of the greater weight.

Even so don't expect it to give much retardation when sitting in it and on
the move, it is only a parking brake, not an emergency brake.
