Friction material has come away from backing plate
Discussion
Thought I would change the fluid today after a trackday at Brandshatch a couple of weeks back and whilst bleeding the brakes noticed that the pads didn't look right, have taken them off and on the front both offside pads have completely come away from the backing plate!
I've done about 3000 miles and a few trackdays so have got my moneys worth out of them but even so they should come apart like this, wondering if it's a manufacturing defect.
I've got a ten mile trip to get some new ones and I'm wondering what the best method would be to put them back, a bit of Aldrite or just wedge them back in without any adhesive?

Ended up using 3m vhb tape 
The only issue is putting them back in is a right pita hence the advice for which adhesives to use.

Have you ever heard of DELIVERY?
They've been fine on track two weeks ago with muliple stops down from 120mph+ so why wouldn't they be ok for driving sedately down to the shops?Have you ever heard of DELIVERY?

I'd at a push understand trying to save them if they were nearly new super high end pads, but EBC reds with a couple of track days behind them?
Stop being a cheapskate and replace them.
Is ANY question of your own safety or the safety of other road users really worth 70 quid?
He's buying new ones, read the post properly before jumping on the professionally offended bandwagon.Stop being a cheapskate and replace them.

Point taken, but you could have made it without coming across as a smary 
. Apologies OP, I saw the pads, the mention of double sided tape and jumped to conclusions. My bad.

Whilst I sort of see where you're coming from, with anything like this you've got to take the approach of "how would it sound in court"?E-bmw said:

"I noticed there was a critical defect in my brake system so I asked an Internet forum how I should temporarily bodge it back together to cover a distance that was easily doable in a taxi or even a push bike (if you have one)".
I had the exact same experience (material broken away from backing plate, albeit not from track use) and didn't drive the car until I changed the pads. I'm not going to prison for manslaughter for the sake of a set of brake pads.
ETA that might sound sensationalist, but if you'd crashed because your 3m brake pad fix had failed, however likely/unlikely, and someone died, it would be manslaughter. For the sake of a taxi journey.

If we're talking about "reading the post properly", let's not forget that the entire point of the post was to ask for suggestions on how to bodge 'em together so he can drive ten miles to go and fetch the new ones... and, presumably, ten miles back again.untakenname said:

It's been said before, and I'll say it again. THAT IS LETHAL.Just because luck has been on side and they only fell apart in removal, doesn't mean they're usable...
If you're taking your car on track days I suggest you should keep at least one set of consumables in reserve i.e. fluid, pads and rotors. In a track environment brakes can go quite quickly from sorta OK to unsafe.
This means when you get your replacement pads, plan to get at least two sets. I guess these are the fronts. Check the rears too if you haven't already.
Just in case it isn't already obvious - don't take the car on the road until you have repaired the brakes; the pads you are showing are not safe to use under any circumstances and nothing you can do to them now is going to make them safe. It seems rather surprising that you can't find some stock pads closer than ten miles, but if you need to travel that far then so be it - but not in your car, which is not currently road worthy.
You might want to consider what caused this and whether there's anything you can do to prevent it happening again.

They didn't fall apart on removal, they already were apart and looks like they have been for quite some time as there's ingrained dirt and grit that's worked it's way in.
Out of interest when I was coming back I waited till the road was clear then performed an emergency stop that was hard enough to pulse the brakes and nothing untoward happened.

This sort of thing, along with pad material breaking up seem all too common.
And it isnt down to one single maker or brand. Although I stopped using Ferodo DS2500's as these were probably worst for either pad material breaking up, or coming away from the backing.
There must be some stupid EU bullst preventing the use of quality materials or something !

That's curious, because I had a similar problem with various other types/brands and settled on DS2500 as the solution.Edited by GreenV8S on Thursday 6th July 10:51
When you fitted / removed them, where the pads fit into the caliper carrier, were the backing plates tight or were they able to slide freely by hand?
I've seen pad material break away from the backing plate where people must have hammered the pads into the carrier as they were so tight that the caliper piston has bent the backing plate like a banana (exagerated) and the material has come off.
