Slipping brake?

Picked up said 372 yesterday and had 5 mins for a clean up and quick play with at the workshop.

 

Nice and clean but noticed the brake slips, it stops the chain from full throttle but if you rev the saw the chain turns but slowly.

 

I'm hoping it may just be dirt around the brake band, am I right in thinking it's and inboard clutch on these? I didn't get that carried away with the clean you see 😜

It stops the chain initially but it then turns, although slowly when revved with the brake on.

 

It shouldn't do that, all saws make virtually no power at idle revs so to slip shows that there is something wrong. Bit like resting the bar on a piece of wood with light force and then trying to rev the machine - chances are it will just bog.

 

Do it at flat out and the engine will be on full chat and stopping it will take far more force.

 

It may be that the brake handle pin has broken, the spring is worn or the linkage has failed. It needs sorting for safe use!
