Yellowstuff pad delamination

[HughS47]

Was at a snetterton track evening last week and the recently new yellowstuff pads that I'd installed delaminated and we were left with backing plate pressing against disc.
The pads hadn't been difficult to install, had done approx 300-400 miles on the road problem free before going on track and one other trackday first. They didn't get excessively hot before failing either, they had felt 'wrong' from the moment we started on the sighting laps.

any ideas what might have happened? I've emailed the online EBC shop we bought them from to see if it was a batch fault with the manufacturing, but is there anything that might have happened?

As a final query, how do people bed in brake pads for trackcars that aren't road legal?

Second time I have heard of this with EBC pads in a month!

I use Rodders pads designed for & tested on track.

I had problems with my yellowstuffs (and the greens) too.

They were fine until they got to half-way down, then they lasted less than an hour on track. These were bedded in as per the instructions on the box.

Other people have had no problems. It could be a case of variability in their manufacturing. Or it could be that some people don't brake that hard


Rodders' pads managed to get down to 1/2mm, and still stopped the car. I'm on my 4th set. Got them on both my track and road MX5s.

I had this with brembo HP pads....



Someone suggested that it could be wheel cleaner.... not sure I believe that

They're crap pads period! Pure marketing gimmick and never lived up to the hype.

Always preferred DS2500 and Carbotech pads, though the latter are heavy on disks.

Mintex work well just for info - i bedded in a set of M1144's on the way to bedford (a bit smelly and a touch of smoke haha) and they loved the track. A touch vague when cold though.

I've found the MX5 to be light on its brakes so those yellowstuffs must be faulty for that to happen!! I had greenstuff previously and they lasted literally years!

[HughS47]

The manufacturer are going to look into it. I've bought some more yellow stuff as replacements as I've had them on the car previously and been very very pleased with them. You only ever hear worst case scenarios in here though, but I suspect ebc have had their issues with some pads in the past.

If it happens to this next set then I'll be changing the DS2500s.

The internet is full of horror stories of EBC pads and I've experienced them breaking apart too.

At best their quality control is poor.

I've heard others suggest it's an issue with cars that are sat around, the pads absorb water - that would be true in my case.
