Having seen the hand brake mechanism during build yesterday at the factory it really is a very basic system.
I would have hoped that his needs simple adjustment having bedded in?

It will no doubt improve as the pads bed in. The disadvantage of rear discs on a light car is that they don't do much so will take a while to bed in. Handbrakes on rear discs are known for being weak which is why some manufacturers incorporate a small drum in the disc for a handbrake. Apparently the VW electric handbrake has a motor in each rear caliper which applies the handbrake, rather than a tunnel mounted solenoid with cables. More to go wrong......

There are a few cars with rear disks and hand brake issues - Vauxhall Corsa and Honda Jazz are in this category. The issue I observed was this: - The handbrake was applied when the brakes were hot. - As things cooled down, the ratchet on the handle was sprung off leaving no parking brake applied. - The driver had (very foolishly) left the car on a slope and in neutral. Please don't ask me how I know this ............. Honest John has more: http://www.honestjohn.co.uk/askhj/answer...or-the-repairs-Please leave the car in gear when parked - we should all do this anyway.

Always leave a car in gear as a back-up. Years ago I learned this lesson when a cable broke and the car rolled off my drive....luckily it is a quiet road!
I park in the garage without brake or in gear.

Apparently the VW electric handbrake has a motor in each rear caliper which applies the handbrake, rather than a tunnel mounted solenoid with cables. More to go wrong...... The Aero based cars have rear discs and a second, mechanical pair of calipers on each disk, just for the hand brake. A bit overkill, but very effective, they lock the wheels! But I rarely apply the hand brake, given that putting an automatic transmission in "P" is a rather more effective brake....

this is not recommended by the likes of Mercedes, as the bit in the transmission that holds the car in place is not designed to act like a handbrake and not designed to handle the forces associated with it.

OK on the flat, but not on a slope!
