It is usually a simple cable tighten and check. They also often get a bit rusty if you have not used them.
Prior to taking the S2/Coupe into the MoT bay I give it a good hard run and use of the brakes. As part of it I use the handbrake to slow me down a few times, this cleans off the surface. Then I ask them to adjust the brakes prior to the MoT. They are friendly and have been doing the small stuff on my cars for ages so they do the sensible thing, but never brake a rule as they value the MoT revenue.
