Car pulling to the left when braking

[Larry 1300]

Hi my Dolomite 1300 was not out last year because of the lockdown. I noticed that she was getting a bit hard to move in the garage as time went by.
After problems getting her started and a stuck clutch plate today was her first time out in 2 years.
Lynn(the wife) was driving and she said that when she put on the brakes she could feel the car pulling to the left.
I will need to take her to a garage to have a look at it.
I have rear brake shoes. Is there anything else that I should take with me parts wise,pads,discs etc.
I saw on a post here that someone had a similar problem due to a seized wheel bearing.
Let me know please.

My money would be on a sticky piston in the offside calliper...

If you take it to an MoT testing garage, they'll be able to get closer to a diagnosis by putting it on the rollers...
