Another reason not to SORN?

[Deeman]

Well at the weekend I went to get the S out after a few weeks on inaction - and it wouldn't budge, and brakes had bound (Fortunately not clutch)......

Managed after some not so gentle persuasion to get it all moving again, but my question is, what component in the brakes is most likely to bind/seize, so I can pay special attention to it should the S not be used for a few weeks?

I have learnt the lesson of not leaving the handbrake on, put it that way!
