Morning.

I'll keep it brief, but looking to understand how 'reasonable' it is for the brake pad friction material to come away from the steel plate due to corrosion.

The pads are the original ones that came with the bike, which is 2 years old, and covered 2.5k miles (I know, poor form).

High end Brembo Pads which have corroded under the friction material so both parts have come away. At the moment only one calliper is off, so could be another failed pad yet to find.

Bike is garage kept and whilst I've been caught in the rain and ridden damp roads, I was under the impression such a critical element e.i. Brake Pads would be able to handle a bit of moisture and muck - bike is kept clean most of the time and definitely washed down if there may be salt on the roads.

Pads are roughly half worn so can't think they would have heated up too much etc so cause the material to fail etc.

Just after some opinions on whether this would be deemed a failure of the part, or just par for the course...

Sounds totally unreasonable to me: I believe my bike is on its original pads, over 17k miles and ridden in all weathers, Brembo brakes.

Unless the rest of the bike looks like it's been dipped in the sea, I think that's crap life from the pads!

I would think it's the bonding has failed, leading to the corrosion rather than v/v?

Sub-standard if you ask me. They shouldn’t do that, ever.

Though I have seen it happen before - to Peter Hickman at the end of the back straight in Jerez. I think he needed to jet wash out his leathers after that.

this happened to someone on the z1000sx forum

suggestion from fake products - apparently there are a few, through to poor manufacturing process on a faulty batch

i think the upshot was to send then to brembo either via their uk distributor or direct

Thank you all. Glad it's not me going mad.

Just to add, pads are original to the bike and I've owned from new.

My assumption is a failure of the adhesive leading to water ingress as opposed to corrosion from external sources leading the failure without a fault present to begin with.

To give a bit more detail, the finish on the lower part of the forks has corroded (the brake caliper carrier) and in for warranty replacement, which has discovered the pad issue. The stantion isn't affected, purely the black finish around it. But other than a light rusting in places on the chain there is not further corrosion or marking.

There was a recall on a batch of Brembo pads, so might be worth checking if yours were subject to the recall and replacement FOC.

Sorry I can't provide any further detail, but I only know because I bought some M4 calipers off a Triumph for my S1000RR and when researching pad options, I found that the pads in the calipers were subject to the recall.

Happened to my KTM 1290 Superduke GT, after only 2.5k miles and 18 months. Dealer replaced them with the pads from a Triumph, as their sister dealer was Triumph and they'd had so many KTM pads fail similarly. M50 calipers on each

My KTM 990 front or brembo pads parted company after 3 years and 35000 miles. Still had a few mm’s on them too.

Shouldn't, but do. Usually on crusty old scooters which haven't worn out the pads yet.

Im very surprised its happened on such a newer bike, but I wouldn't be calling brembo pads ' Hi-end' particularly.

Take your point ref. Brembo and hi end. The cost of the bike and replacement parts means they should be though biggrin

Will check about the recall.

I remember certain pads having a habit of doing this I think it was EBC red, many years ago

If you used them in the damp and then left it parked up, the pads would separate

Rear pads or front?

Rear pads happens. Premium or not. This happened on my GSXR-750 in about 2014 (there will be a thread on the search somewhere), the rear pad friction material came apart from the plate, the bike was used but almost new. I was outraged at the time after a conflab on here and some research, it turns out whilst it's not common, it does happen.

Typically affects rear pads, I was informed the friction material can corrode if you don't use your rear brake enough to dry it out.

I'm also intrigued as to how the pads are half worn in 2.5k miles, or have you done a lot of racing or heavy track days?
It sounds like faulty pads.

That happened to my mate on his KTM with Brembo pads.

It happened on a track day at Knockhill but fortunately on the warming up lap, the material just popped right out the calliper.

He’s anal about maintenance and looking after his bikes in general so who knows the cause?

Happened to me on a Honda CB650 some 5 years ago. Luckily it was the rear brake. I did ride throughout the winter & didn't use the rear brake much, so I'm guessing corrosion/salt/damp/dirt must have caused most of the issue. Mind you, bike had only done some 7k miles, so I was a bit surprised....

I’ve had this happen too, though not on a bike. Rear Pagid pads on my Megane RS fell to bits when I took them out for replacement. I was quite surprised. They had about 3mm left on them and weren’t more than a couple of years old.

Fronts. Only one side, other set were fine.

I'll be honest, I hadn't given it much thought. Rear Tyre is on the way out too. I'd add it ride small b / c roads- rarely do I use a roads and the like and living in the middle of the countryside the roads are 90 degrees this way, then the other etc etc. Tbh probably should get a super moto or something a little more suited.

Happy to be corrected if it does seem odd, or my riding style is ham fisted. Intermediate track day rider so no racer or even quick in the grand scheme of things!
