My tip for you will be to check the wheels after you stop the car, ie after a run, place the back of your hand near the spokes close to the centre of the wheels, if they feel warm, especially the rear ones, then you probably have a partially seized calliper, the fronts would normally be slightly warm from normal use, if they feel hot, again maybe partially seized callipers.
If the rear callipers are aluminium, then salts start to build up on the calliper piston surface and cause it to stick out more than it should, also the same salts start to form under the score seal and that has the same effect - even I have had these issues with VW Group cars. Steel/Iron callipers seem to suffer from the steel ring built into the piston dust cover rusting up and gripping the pistons - I've not had that
problem yet.
Of course if any brake is sticking, it might just be that the pads are seizing in the callipers due to a complete lack of maintenance/care!
