Washing machine motor brushes

I've got a machine like this

've replaced the brushes many times, always with ones on the left in the following picture one in the centre and on the right I have just recieved via Ebay. Here are the the three again in profile plastic carriers look similar, but the metal inserts and the carbons themselves are fatter and I am worried that they will damage the armature if I fit them. Described as Hotpoint / Creda Carbon Brushes & Holder What do you think?
