Ignore the noise, quite often the brakes wont even work after a lay up. So riding with brakes slightly on is needed, until they start to bite. The same may work to stop the squeaking, to clean up linings a bit and get rid of rust on the drums. You could dismantle and clean, but next week when the bike comes out again rust has returned.

Dave, what a good film, I enjoyed the ride round the houses.
As Rob says, now't to worry about very normal indeed. I have squeaks on my anchors to start, it is often worse when it's cool/damp in the air weather conditions.

Now we all know where you live, Big Bro will be round for tea :lol:

It was a heath Robinson set up, I could not find my bike mount so I used insulation tape and taped it to my chest, it is a small Kodak HD Zx1, works very well. The ignition was on I the other side is E so i presume that E is emergency is that correct? The choke is a bit of a mystery if you push it the other way the choke is on i have to leave it that way and the choke slide then is all the way to the top of the carb. Not sure if this is right or not, Anyone ???

Thank you for the comments. It's nice to have help and reassurance that i am doing it right.
If you can find me your welcome to a cup of tea. LOL.
Glad I don't have to worry about the brakes, but i will take the wheel off and have a look. The back brake is very strong the front is a bit weak in comparison.

It's a good idea to check the brake anyway, there is always the possibility that the shoes could be worn.
If in doubt check it out!

If the front brake is weak cleaning may help.
But I have had brand new linings and the brake not work hardly at all. They do take a bit of bedding in, just a few short runs is no good. Ride with brakes on to bed them in or clean them of mist, dampness, muck etc.
Choke slid. Open the throttle wide open, check the slide is all the way down when the lever is fully on choke, now check the choke slide goes all the way up, for running when the bike has warmed up a bit. The slide should not stick and have full movement up & down. If not fully down check sticking and spring, if not fully up and you have the correct cable, take up any slack on the cable adjuster at the top of the carb.

Brakes. Assuming the cable front or rod rear is adjusted correctly. A visual check for wear can be made.
look at the levers on the drum. The angle should be more than 90 degrees. If less than 90, the linnigs could be worn, OR, you need to pack them out, do this by putting a shim washer on the " mushroom " stem, which will open up the lining dia. You will then find you will need to slacken adjustments to rod or cable. The packing makes a lot more adjustment available, not so much packing that brakes bind though.

Thanks Rob, I took the front wheel off, now I have no reference to how much lining should be on the shoes, If you look at the pictures are these ok?
