I do remember using it quite a bit in the very dim and distant past, especially on mini shoes. Then exchange shoes became the big thing but still with riveted linings. The tool was still very occasionally useful for tightening up the odd slack rivet (which could cause brake squeal). Then they started in with the bonded linings and it went for a long sleep in the "punches" sector of my tool box. I only remember using it once since then and that was to reline a set of riveted shoes for my old DAF 33 van, which used the same linings as the mini, when I couldn't get a proper DAF specific set of shoes.

Everything is bonded now and I'm always nervous about very old looking bonded shoes as I've seen a number of old shoes where the bonding has failed. If the lining comes away from the shoe whilst on the move it can get jammed between the shoe and drum instantaneously locking up that wheel with potentially disastrous results. If your linings/pads are not in the first flush of youth, next time you're working on them - perhaps at service time (which is one reason I like to closely inspect brakes at every service. ie. every year) have a very careful look at the join between the friction material and the metal backing. You may find reason to be concerned.

There was a place near me by M40 Junction 1 on the way in to Uxbridge that used to replace the riveted linings if I took my shoes in, but it's over 10 years since I used them. I couldn't find them again so maybe they've gone. Now I get exchange shoes and post the old ones back - presumably they are getting re-rivetted somewhere, so those skills are still certainly useful. Unless they send them to India.

Thanks for the tip about the bonding failing on the Panda's shoes. Mine certainly took a hammering getting the rusty drums off. As the OP's experience and above video show, they can detach even if they're not that old. Max. 6 years old in the Bodgit & Leggit video?

Well absolutely. Why not? probably because it would then have to be a dedicated fitting for this vehicle only whereas I suspect a lot of wheel cylinders/caliper pots are generic and used on several different vehicles? maybe even across manufacturers? After all it's not the individual vehicle manufacturers who make them is it.

Fiat have used the same drum brake wheel cylinder for donkey's years. The 1980s Uno had the same brakes and I suspect the parts go back way before that. The issue with all manufacturers is they don't bother themselves with corrosion. The issue with Fiats is the back brakes last too long so they are trashed with corrosion when its time to replace.

If the back plate is rusty - take it off de-rust, paint, etc.

Deeply grooved brake drums are worn out. But costs are low so replace the lot anyway. Rusty cylinder with flaking bolts is also well past it's use by date so change it out along with the brake pipe if necessary. Brake back plate ditto.

I agree, parts like drums at about £20 each new, old are not worth refurb the effort removing lip, rust etc

Hope that illustration is for "illustrative purposes" only Dave? The cylinders don't look like mine and the drums look as if they're for a 5 stud hub? The spring retainer clips look different too but might work.

I find this is the thing with mail ordering. You have to be so very careful because sometimes what arrives is not what the advert illustration showed and sometimes even when the advert illustration looks like what you want something else entirely arrives or is of a completely different brand to that advertised.

I always check with the supplier before ordering but to date have not had a problem. Under eBay rules the supplier pays if product is incorrectly listed. Not much fun if you are planning the job but it keeps them on their toes.

For 100% certainty go to Shop-4-Parts. drums (£42) + shoes (£27) + cylinders (£13) + VAT = £98 The retaining springs etc would be extra.
