Handbrake failure after brake pad changed

Well the handbrake was working when your son parked the car.

It probably was working when the garage parked the car up after working on it.

Do you expect them to park it on a slope for ten minutes to test it?

My husband  parked in gear, even in our garage. 

The handbrake is working if it can manage to hold the car indefinitely, not just 10 minutes.

What sort of car is it?  Some moderns have separate disc and drum arrangements for the rear service and parking brakes.  Whilst most have the parking brake drum built into the disc, it would be theoretically possible to replace the disc itself, calliper and brake pads without disturbing the handbrake shoes.  

And I may be misremembering, but isn't there some sort of adjustment procedure one does when the rear brakes are disturbed?  I seem to recall it being necessary to pull the handbrake right up and let it off again once or twice to ensure the shoes are fully advanced to the drum facing.  

A Mini Paceman?

Came across this years ago. If the brakes get hot then when parked and handbrake applied no problem - until the brakes cool down at which point the car if parked in neutral on a slope will wander off.

Digging about suggests that the new Minis have a handbrake that acts on the rear discs, so the point about the drum in disc arrangement, I think, may be ignored.  It feels like more than coincidence, therefore, that the handbrake 'failed' immediately after the replacement of the rear caliper and discs.  The trouble is proving it, however, and the fact that the car wasn't left in gear.

Few years ago I received a letter from my car manufacturer advising to leave the car in gear when parking on an incline as there have been cases where that particular make of car had moved when parked on handbrake only. The letter also stressed it was not a recall matter.  No, it wasn't a Mini.

Vauxhall had a problem with the handbrake flying off if it wasn't fully set into the ratchet- like if you pulled it on with the button in, then let go at the end. My late father's vectra used to do it, but it was an auto, so all that happened was you needed both hands to get the thing out of park if it happened on a slope.

What could have happened here is new pads on old discs not bedded in properly causing less braking force, then when the discs contract slightly it reduced further. Doesn't explain how it would rocket off on a very gentle slope though as seen on the CCTV
