Been having a right old time of it with the brakes on Harvey. Won't post a bunch of pics, but it has S2A 109 axles and 11" brakes - which is great except the TLS front brakes are a NIGHTMARE to bleed. I ended up replacing the entire brake system except for the steel lines, then spent a week, no exaggeration, bleeding the brakes. In the process I ditched the knockoff brand VH44 (which was leaking air) and fixed the rear adjusters that were slipping as well. Its now got fantastic brakes, which is nice.
Today's job was to sort out the light switch, which has a bit too much play in it and you can turn it past 'on' which is no good. I had another complete switch but no key, so I ordered a new barrel and key and went about fitting them up. First off I ran the switch through the ultrasonic bath because it was disgusting. Could not find instructions anywhere how to pull it apart so here's some pics I hope help the next guy or gal...

you bend out the little half moon tabs here and the unit slides apart.

this detent ball in here is how you get the lock barrel out. You can do this with the whole thing together, in theory, but it would not release on mine, and still wont even after putting it all back with the new barrel. YMMV.
[edit]: forgot to say, its tricky to get the barrel out without a key, which is why I had to disassemble the whole thing. Once you can get to the wafers in the barrel you can press them down one at a time as you slide the lock out of the mechanism. You put the key in the lock to insert the new barrel.

this shows the detent ball on the barrel, as well as the other ball and spring that are in the main body under a brass grub screw.

Here's mine all reassembled. I gave the surround a quick dust of black paint just because.
If you take your time and keep track of where things go, take some photos or whatever, you cant really go wrong. its a very simple set up.
Off for a roadworthy cert this week then I can get on with some more upgrades.
