Brake lining glue

The 'glue' used might well need carefully controlled temperature and pressure to cure fully.

Makes interesting reading, all these comments. If I'd asked what glue to use to stick an aeroplane together I'd probably have got the same replies. But they do stick aeroplanes together with epoxy glues.

Now, you may be right about the brakes. But seeing the invective generated leads me to think that it's lemmings talking with a knee-jerk reaction.

Here's a link that may throw some light on the topic.

That's the first reasoned reply I've had. You can usually tell if people don't know what they're talking about when they start to rant.

Thanks.

Rob

True. And they do the same with car bodies. It's pretty specialised stuff though.

It's probably just it sounds a bit like extremely unwise penny-pinching in your original post, and people are reacting to that. I wouldn't do it, but if the shoes were hard to come by, I might ask a specialist to do it for me.

You could, but is it worth it? If the car is a rare classic, maybe. If not, probably not. If it's a 'normal' car, just go and buy some good quality shoes. Brakes aren't worth mucking about with.

It used to be that way many many years before even I was born but even then you wanted someone to do it for you or they were rivetted on.

These days unless you *really* can't buy a new set 'cos your car is so rare then diy glueing is a mugs game.

The car is a 1955 Merc. The linings are all glued on. In the distant past, and for some reason I don't know, the front linings are in two halves and one half on one shoe has fallen off. It just fell off when I removed the shoes for unrelated repairs and now I need to get it back on again. I suspect that the other half might fall off as well if I tapped it. The surface of the shoe, which is made of alloy, is covered with corroded dust, which is obviously why the lining fell off.

Rob, I think you'll find a large number of the people in here are in the Engineering and Automotive trades and know a hell of a lot more about the subject than yourself. We are simply incredulous that someone would rather save a few quid (literally) and risk their life and those of other people on the road around them. The rants are being put forward simply because they dont want you to sacrifice your safety. If you do not wish to take those opinions into consideration (having asked for help in the first place) then im not sure why you asked.

No adhesive company in its right mind (read as Araldite) will give you the go-ahead for this idea. Epoxy resins, used in planes, are very highly specialised compounds and require PRECISE cure and post-cure treatment and temperatures and are still only capable of dealing with

That may well be so, and I would bow to superior knowledge. But I can't tell from a rant full of swear words whether that person falls into that group. The more cussing I get the more I'm inclined to disregard my informant - which could be to the detriment of both of us.

We are simply incredulous that someone would rather

No. They are just having a go. And then the next one does it because the previous one has! Like a lot of sheep.

If you do not wish to take

Reasoned opinions from someone I can trust are always welcome.

I wait to see.

Epoxy resins, used in planes, are very highly

Yes, I understand that.

Sure. But if there's a glue which is the right glue, then I want to know. Which is why I asked.

We'll see.

Thanks for this, anyway.

Rob graham mumbled incoherently to the rest of uk.rec.cars.maintenance:

Admittedly there are good ways and bad ways to respond but swearing doesnt necessarily mean they're wrong as you know.

Its a "community", and in that community banter generally occurs. You have to accept it to some extent to come out alive, theres still good info there.

I can see the terrified look on their lawyers faces :)

Fair enough you did ask about the proper stuff, but then you threw in araldite and normal epoxy - neither of which will cut the mustard safety-wise and I think thats what sparked the ridicule. If you'd left it at "whats the right stuff" you might have gotten a better answer.

Incidentally, how hard is it to get parts for a '55 car these days?

Coyoteboy mumbled incoherently to the rest of uk.rec.cars.maintenance:

Also, as you're probably aware, old brake shoes (presuming they havent been replaced in the non-too-distant) could contain asbestos so watch what you're doing if you have to prep the surfaces to bond.

It's frustration built up after years of dealing with d*****ad customers who'd rather save a quid than do the job properly and having to sort out the bodges they've done when it all goes wrong

And even then they can come off. I had a two-day old pad split on me once (new VW Golf VR6, dealer serviced) and I spun it on a roundabout as a result. That was a new-trousers moment if ever there was!

So trying to DIY it is possibly the dumbest idea in this particular box of rocks ever.

They're not the original linings then. If they're "linings" (rather than "pads") and they're "old" then they would have been riveted in place, not glued. It was a common task (any local garage), and even now it's still fairly common on classics, to replace the lining alone and re-use the old shoes. Obviously this is easier if you keep a spare set of old shoes!

It's hard to find people who still rivet linings. You need someone with a riveting machine (rare), probably a drilling machine (rarer, because of the dust hazard) and maybe even a setup for taking generic lining material, forming it to fit an unknown model of shoe and doing all the drilling and riveting from scratch (very rare). You'll find the first one if you talk to commercial vehicle brake specialists, but the last might need phonecalls in the back of Practical Classics.

If you can find any "Newnes handbook of servicing the new 1950s cars" book, then it will be described in there.

Trying to glue them on though is a fool's errand. Even trying to glue them on to old shoes in a proper lining-gluing factory is probably risky.

It'll cost more than new pads for an Escort, but less than new shoes for a '55 Merc..

Of course if it's a '55 Merc with _disks_, then Rob can afford it!

Well, that might be a different matter. I doubt you can pop down to Halfrauds for a set. Probably time to talk to a specialist reliner. Have you looked in one of the classic car magazines?

Yes. I'm trying to remember when bonded linings on shoes became common - I'd guess at the late '60s. Of course certain early brake pads were bonded before that but then they don't have the same shear stress on them.

Andy Dingley mumbled incoherently to the rest of uk.rec.cars.maintenance:

Actually a lot of older brake parts have been used up to very recent years on base models so its possible that they're still available fairly cheaply.

=============================== I was still doing my own bike shoes / linings up to about 1962 but I think that the Minis I had from 1964 onwards had bonded shoes so the changeover was in progress probably around 1960.

Rivetting linings was definitely a DIY job for bikes at least. A small 'anvil' to fit in the countersink in the shoes against the head of the rivets was held in a vice. The other side of the rivet was then turned over either with a rivet punch or with the end of a 1/4"round bar.
