101 brake drum must have shrunk ...

AJG uttered summat worrerz funny about:

Try the shoes on another axle which you know the cylinders work on. If it fits then it'll be the cylinders that are some how wrong.. if it doesn't then It'll be the shoes.

Do the cylinders have a profile on the slot in the piston? If so is this the wrong way around? I.e. Would rotating the piston by 180 degrees put things right?

Could be way off the mark but just thoughts off the top of my head.

I had many sets of shoes (for various vehicles) in the past that have needed judicious attention with a file where they pivot and touch the pistons to make them fit. And conversely I've had the occasional set (all have been Mazda shoes) that have needed a small application of weld to build them up so they will adjust corectly.

So long as the lining radius matches the drum and the extra adjustment needed is only slight filing them is an acceptable option.

PS. Having absolutely no idea about the way 101 brakes are designed (and if they are twin-leading shoes then ignore this) I will also suggest checking that you have the leading and trailing shoes correctly positioned.

Must be all that rain weve had shrinking them :)

twin leading shoes on every wheel, AIUI, which is a bit of a daft thing to do, as it means it's got hopeless brakes in reverse. I believe this is what's known by software engineers as a "feature".

You don't start a climb unless you a damned sure you are going to make it! The brakes are only just passable going forwards, going backwards you might as well drag your foot on the road....

It's probably granny, eggs, sucking etc - but you have got everything the right way round? Usually the problem with drum brakes is the exact opposite...... ;-)

A least we know why the Italian armt didn't buy them :-) Richard

Why would the Italians need brakes going backwards for? I'd have thought they'd want strong brakes forward but none backwards...

hehe, nothing like a bit of johnny foreigner bashing..

Just trying to think up something French-related now.

Everything looks correct ... adjusters on the snails, springs in the spring holes etc. and the pair of shoes look identical. I did the near side today in about 30 minutes except I didn't replace the cylinders. I've measured everything and I can't see the difference. I've reseated the shoes again today and I'll be blowed if I can see what's wrong. My next trick is to put the shoes into the drums loose and make sure there isn't a twist on one of the shoes ...
