Who's the sadist that designed the rear master cylinder setup for these?


Ok I feel better.
Is there any time proven trick to re-attaching the return spring? Seems that about a dozen things need to align properly to make this happen. Or am I overlooking something?
Thanks, Mike

You mean other than removing the left-hand silencer, rear wheel, final drive chain and the skin from four knuckles!? :p

Seriously, Mike, what you need is:

1) good stiff piece of 1/8" or 3/16" round stock and bend it up like the photo.....(hint: a coat hanger could work if you use it in loop fashion)

2) If you don't have strong fingers use a pair of Vise Grips to grab the handle end of the hook you fashioned....will save some skin on your fingers.....

3) I use a screwdriver in the other hand to 'persuade' the end of the spring over the edge of the trunnion lever...

HTH,

Steve

Actually, if you remove the engine from the frame, you can raise the rear brake lever high enough that the inner lever just drops into the spring loop. Then the rear brake lever can be pushed down by hand 'til the trunnion engages on the master cylinder threaded rod, followed by the forward securing nut. Then just replace the engine in the frame.

Hth.

Thanks for the replies.

Hmmm- maybe not the engine, but how about the footpeg?

I've decided I like drum brakes.

Mike... visit Harbor Freight and look for a set of auto body pull rods... they look like Jubee's photo but are made from spring steel and have "T" handles made on. Work slick as owl poop. If no Harbor Freight local to you see an auto body repair parts house... most fair size communities have at least one. Or even an automotive paint store could supply a set. Mine came from Snap-On but they cost dearly. Happy trails... and long live disc brakes! :p

All I do is get a couple of foot of wire (or strong string/twine), tie it in a large loop, hook it around the spring & use it to pull the spring back over the lever. Sometimes a large screwdriver is needed to persuade the spring to slide across the lever, as described above.
Two things can go wrong. If the string/wire isn't strong enough it can snap & you'll punch yourself in the face (embarassing AND painful), or the string/wire can get trapped under the hook on the spring (just cut it & pull it out). Easy. But the setup was designed by a sadist.

I used a large cable tie made into a loop. It is strong enough material that you can 'pop' it out from between the spring loop and lever plate if it gets stuck.

Or fit rear-sets and a modern cylinder in a sensible position laughing

It's an odd setup - one which I've sworn at several times.

Well, it's on.
Used a good sized loop of safety wire padded with a couple of rags for my sensitive fingers.
