Relining brake shoes

Post by **mowogg** » Wed Mar 26, 2008 6:18 pm

i have got some replacement liners and rivits for my front brake shoes -remvong the old liner was easy (drilled out copy rivets) -does anyone have any tips on hot to fir the new ones. Presumably i need to clamp the liner on, and fit the new rivet. Is there a speacila tool to clamp down the new rivet?

This is not something that most would bother with these days - and beware the old shoes you took off may contain asbestos. Hopefully the new ones (unless v old stock) will be asbestos free. You will need an 'anvil' shaped the size of the rivet head - clamped in a vice - and then assemble the rivet/lining/shoe in that order and simply spread the rivet on the underside of the shoe with a blunt punch. Best to start in the middle and work to either side i would think - and maybe do each rivet loosely at first then run along them a second time gently firming them up. Risks are that the rivet will be clenched too tightly and will 'crumble' the lining around the rivet - and risk of the lining not being completely flat on the shoe - may need to be filed smooth. Good luck!

Blimey, re-lining them? Just get some new ones!!!

Still, looks as though BMC has answered your query anyway

WOW, I don't think I've ever known anyone reline their shoes. Is that obsessive period authenticity

is it cheaper or are you just curious?

either way, I'd be interested to see how you get on

I have done it - 40+ years ago - for a Morris 8E.

All my linings have been fitted by myself using the method described above and I have never had any problems with them. I used to buy them from a company that advertised in the exchange and mart many years ago, and I still have an unused set left! I suspect all of mine have asbestos in. Did you buy these recently or have you had them in stock for a while?

Nice to see the old school skills haven't died completely. I used to reline truck shoes many moons ago.

The asbestos linings tend to fade less and also are less succeptible to self induced vibration and heat cracking...
The same goes with clutch linings.

Best not to breathe the dust though!

There was a punch ,to set the rivets
it has an indentation on the face ,that
rolls the rivet out from the centre.

I know a moggy owner that buys as many of the old type shoes/liners as he can when he attends the auto jumbles etc. He swears by them. His exact words are ‘’I can stops on a sixpence.
He claims his drum brakes are as good as any disc because of the old type asbestos in the brake linings.

I agree - old linings are far better than the modern 'camel dung' linings! It may be this factor that has induced the rush to discs!

I think modern friction materials are just too hard for everyday use (discs and drums) Nowadays it is more common to change the disc/drum where as years ago they would last far longer.

If true then the danger of asbestos, must of been considered more of a hazard than poorer stopping power!

the banning of dangerous materials has nothing to do with the car industry! Every year something else gets banned.
In the process a huge amount of effort is created to re-validate automotive components. One of the biggest in recent years was the billions wasted to remove Chrome-6 from fastener platings.
Chrome-6 has a very toxic process (for the raw material IIRC) therefore to ban the sale of old stock was just ludicrous!

If drums are as good as disks then the laws of physics have been broken.

Depends which law ! If friction material area is the important factor - then drum brake shoes (even the small 8" drums) will beat pads handsdown. Drum brakes will lock the front wheels - they just won't do it over and over again - but realistically, is that often a factor in normal use ?
