The chain brake on my old 266 keeps engaging,I have tried to adjust but

with no luck.Is it just old and worn out or is there anything I can do to cure this ?. Thanks.

You will need to strip it and inspect for wear but my thoughts are that there is either a wealth of crap in the mechanism that needs cleaning or the pivot part - 501 87 53-01 has worn.

 

The attached files may help - I am thinking you have the older metal handled chainbrake.

The brake on my 254 (same era, same design I think) is also slightly sickly, in this case it's part 501 87 47-01 that's broken off. The prong-y bit that the brake handle rides along. Might be worth checking since it seems the flimsiest part of the assembly...

 

Not that I have much of a clue, just mentioning because I've literally just had mine apart.

Yes - you said you had adjusted it - the newer plastic handle is non adjustable - you may be able to pick up a cheap secondhand unit off ebay.

 

The two prong spring that Adamn mentions is easily broken on stripping and is on the newer units.
