Technically the same thing would happen if using drum brakes
. Apply the parking brake and the shoes press against the drum and could likely freeze there.
The front pads froze to the disc, the piston of the caliper has no return spring so the pad is always in slight contact with the disc.When driving it is only the runout of the disc that gives any clearance, so when parking on the driveway after braking to a stop there is no clearance. On drum brakes
there are return springs that always leave some clearance as long as the parking brake is not applied.I would not recommend leaving the hand brake on for weeks at a time. It would be interesting to hear from owners of trailers with disc brakes
if there are in fact any drawbacks.
