I have had these on for a few years and 20,000 miles odd I think im not complaining just giving heads up for others

anyway more importantly might have had a near miss, as with checking calipers last week spotted something odd with rear pad

pad has come off backing plate and lodged against inner disc diameter

these were ebc green stuff pads been on a few years now

not sure if alloy wheel cleaner and washing regular has harmed them as surface looks rusty pitted unless occurred after pad has detatched.

anyway some ebc red stuff just gone in

and possibly best buy this year(£16)caliper rewind tool kit

Do you take out the pads each service for checking and lubrication the slides?
This is recommended practice although it does not appear on the Fiat standard service schedule.
You are not doing much mileage but you still need to service at least once a year.
I've had Ferodo pads separate from their backing plate but that was years ago, and I would have thought modern materials would be much better than those of old.
 
This shouldn't happen. Send them to EBC for comment, they may replace them for free as goodwill.
Possible cause could be impact some time before fitting. Anywhere from factory line through all its distribution network, to the fitter. Could have been dropped at any time, so blame cannot be placed. Avoid brake pads in damaged boxes. Could have been a problem in manufacture. All brake manufacturers are very careful, including EBC.

Let them have a look. They may be able to see an answer. All you could lose is the postage. They may be grateful for the feedback. Just ask them nicely if they can advise what happened.
 
WOW! in all my years I've never seen this happen before! :eek: just glad you spotted and rectified it before the worst could've happened :( ...... in all fairness I agree with portlands comment that it should not have happened. i'm currently using the red stuff pads too and coincidently had them out to do my rear wheel bearings. they've been on for about 8000 miles now and a quick rough up with some emery cloth and a dab of copper grease and there just as good as when they were new. I can only think that perhaps you had a bad batch as I can't imagine EBC (who lets face it have been making pads and shoes for all our grandads first cars) making poor quality stuff all the time? lets just hope that no one else has this trouble :confused:
 
Seen it many times when in the warranty dept. of a major parts supplier. Seen it demonstrated by dropping a pad from waist height onto its edge. Not much protection in its box, so when buying new, avoid boxes that look dropped.
 
Hi,
seen this a fair few times over the years,


it's the RUST you mention that's the key..,

it gradually "lifts" the friction material from the backing plate,until it LETS GO,
sometimes VERY spectacularly,
shoes on the rear is particularly common, in country / regularly flooded area, the water / damp can just sit in the drums and the shoes just "sweat", when the rust eventually ruins the bond, one lining gets wrapped on top of the other locking the wheel solid..EEK,
Charlie
 
seen a few comments on alfa forum similar with green stuff but mostly related to track days etc
the rears don't do much work relative to front but I do do a bit of hard braking time to time.
I still think the regular acid wheel cleaning has aided to the demise and as said above once behind the material rust has set in.
I cant say for sure how long it was detatched but it seems strange that it has even stayed in there rather than just flying out during driving.
 
I read somewhere that EBC pads were prone to failure from heat damage due to hard use. Excess heat causes the glue to fail iirc.

Never had a problem with EBC myself and I've been using them almost 30 years.

Just tried Googling it but can't find the article I read, I'll post again if I find it.
 
Its not put me off ebc, the red stuff rears are bedding in now, dont know if warmer weather ir caliper free off n grease but mpg has shot up today, will see how it settles for the week. Its downhill to work uphill back home, so need return trip till i get to excited.
 
Exactly the same thing happened to me with EBC greenstuff pads. Girlfriend was driving the car at the time as she was working away, doing about 600 miles a week. She was complaining she could hear some banging noise from the rear every now and again.

Didn't get a chance to look at it for about 7 weeks but when I did I noticed the pad material had come clean away from the backing plate. Luckily the pad material had stayed in the carrier and the banging noise was it moving around.

I've just recently change the rear pads and discs on my other car (Clio 182) and when I removed the rear pads half the pad material had gone from one of the pads looks like it snapped clean off down the middle, they were genuine Renault pads which were being replaced, they still had lots of meat on.

Scary stuff.
 
see it quite regularly on our trailers at work that dont do particularly heavy loads... certainly water/fluid related be it wheel cleaner or just rainwater... our road salt doesnt help.

it seems to be a combination of non-regular heat cycles and in our case water ingress. the pads (AND shoes) never really get hot enough to burn off the water and in winter when the temperatures drop and the ice slowly penetrates its never good news.

on the other hand the equipment that runs hotter brakes due to the work they are doing don't seem to suffer from it!

one more thing with the drums that we find is that the lighter loaded trailers tend to glaze the shoes up quite quickly as they will spend a lot of the time running up and down motorways then brake to come off and a lot of our customers for the lighter loads aren't far off the sliproads! they seem to cook the extremity of the shoe and leave the cores perfectly fine
 
I use EBC Ultimax pads (tight git) and I've had a set of front pads detach from their backing!

It was only when I felt a slight tug when braking (material was obviously moving round) that I noticed the fault! Pads were maybe slightly over 50% worn.

At the time I put it down to corrosion of the pad/shoe backing! My mileage has dropped considerably over the last couple of years and I lucky if I do 6000 miles so that may explain why they rusted up.
